Abstract:

Integrated mapping is essential in geological studies to assess risks of earthquake hazards. Cartographic techniques have become a commonplace approach to visualizing data in the continuous geologic and geophysical fields. However, traditional GIS mapping is a manual process with a time-consuming workflow that can lead to mistakes and misinterpretation of data. This study applied two mapping approaches to address this problem: Generic Mapping Tools (GMT) used for automated cartographic workflow employing scripts and QGIS used for traditional geologic mapping. The study area includes Ethiopia, notable for its complex geologic setting. The study aimed to analyse the relationships between the geophysical, geological, topographic and seismic setting of the country by presenting six new thematic maps:1 topography based on the GEBCO/SRTM15+ high-resolution grid;2 geological units with consistent lithology and age from the USGS database;3 geological provinces with major Amhara Plateau and Somali Province using USGS data;4 geoid based on the Earth Gravitational Model 2008 (EGM-2008) grid;5 free-air gravity anomaly model using satellite-based remote sensing data;6 seismicity showing earthquakes and volcanos from 05/03/1990 to 27/11/2020.The comparison of the topography, seismicity, geophysics and surface geology of the Afar Depression and the Great Rift Valley was based partly on extant literature on the geologic setting of Ethiopia which primarily focuses upon discussing tectonic processes that took place in the East African Rift System in the past. The current study contributes to the previous research and increases cartographic data on the geology and geophysics of Ethiopia. The outcomes can be implemented in similar regional projects in Ethiopia for geophysical and geological monitoring.

Abstract:

Availability of multispectral remote sensing data cheaply and its higher spectral resolution compared to remote sensing data with higher spatial resolution has proved valuable for geological mapping exploitation and mineral mapping. This has benefited applications such as landslide quantification, fault pattern mapping, rock and lineament mapping especially with advanced remote sensing techniques and the use of short wave infrared bands. While Landsat and Aster data have been used to map geology in arid areas and band ratios suiting the application established, mapping in geology in highland regions has been challenging due to vegetation land cover. The aim of this study was to map geology and investigate bands suited for geological applications in a study area containing semi arid and highland characteristics. Therefore, Landsat 7 (ETM+, 2000) and Landsat 8 (OLI, 2014) were compared in determining suitable bands suited for geological mapping in the study area. The methodology consist performing principal component and factor loading analysis, IHS transformation and decorrelation stretch of the FCC with the highest contrast, band rationing and examining FCC with highest contrast, and then performing knowledge base classification. PCA factor loading analysis with emphasis on geological information showed band combination (5, 7, 3) for Landsat 7 and (6, 7, 4) for Landsat 8 had the highest contrast and more contrast was enhanced by performing decorrelation stretch. Band ratio combination (3/2, 5/1, 7/3) for Landsat 7 and (4/3, 6/2, 7/4) for Landsat 8 had more contrast on geologic information and formed the input data in knowledge base classification. Lineament visualisazion was achieved by performing IHS transformation of FCC with highest contrast and its saturation band combined as follows: Landsat 7 (IC1, PC2, saturation band), Landsat 8 (IC1, PC4, saturation band). The results were compared against existing geology maps and were superior and could be used to update the existing maps.

Abstract:

Ghana is a country exceptionally rich in geologic mineral resources with contrasting topographic relief and varied geophysical setting. This paper evaluated the geological and geophysical setting of Ghana with a special focus on the impact of the geologic setting and topography on gravity. Specifically, it assessed how variations in geology, topography, landscapes and the environment control the geophysical parameters and how these vary among the major regions of the country – the Volta Basin, Northern Plains, Ashanti-Kwahu (Kumasi) and Coastal Plains in the Accra surroundings. Previous studies utilizing traditional Geographic Information System (GIS) approaches have documented the geologic evolution of Ghana evolved as a part of the West African Craton. As a contribution to the existing research, this paper presents a regional analysis of Ghana by integrated mapping of geology, geophysics and topography of the country. The technical approach of this research focuses on utilizing the console-based scripting cartographic toolset Generic Mapping Tools (GMT) integrated with QGIS for processing and mapping the datasets: General Bathymetric Chart of the Oceans (GEBCO), Earth Gravitational Model 2008 (EGM-2008), gravity grids. The theoretical background is based on the geologic research of West Africa supported by high-resolution data. The paper defines a conceptual cartographic framework for integrated geologic and geophysical visualization in a regional-scale mapping project on Ghana.

Abstract:

Geology and all geological structures are three-dimensional in space. Geology can be easily shown as four-dimensional when time is considered. Therefore GIS, databases, and 3D visualization software are common tools used by geoscientists to view, analyse, create models, interpret and communicate geological data. The NGU (Geological Survey of Norway) is the national institution for the study of bedrock, mineral resources, surficial deposits and groundwater and marine geology. The interest in 3D mapping and modelling has been reflected by the increase of number of groups and researches dealing with 3D in geology within NGU. This paper highlights 3D geological modelling techniques and the usage of these tools in bedrock, geophysics, urban and groundwater studies at NGU, same as visualisation of 3D online. The examples show use of a wide range of data, methods, software and an increased focus on interpretation and communication of geology in 3D. The goal is to gradually expand the geospatial data infrastructure to include 3D data at the same level as 2D.

Abstract:

ABSTRACT Basutoland is a former British Protectorate (now the Kingdom of Lesotho) nestled in the Maluti and Drakensberg mountains, surrounded by South Africa. Geological knowledge about Basutoland started with the activities of French missionaries in the 1830s and continued to accumulate throughout the nineteenth century. Systematic geological mapping began in 1902–1904 with the work of Ernest Schwarz and Alexander du Toit, who, while working for the Geological Commission of the Cape of Good Hope, extended their mapping activities into Basutoland. In 1905 Samuel Dornan from Morija started studying the geology of that region of Basutoland. In the 1930s rumours about the finds of diamonds prompted the British Government to map the country geologically. Gordon Stockley, a geologist experienced in mapping for the Geological Survey of Tanganyika, was seconded to Basutoland in late 1938. Stockley mapped the whole country in 11 months in 1939, and then returned to Tanganyika. His geological map, at a scale of 1:380,160 was published in 1946, and the report appeared in 1947. At the start of his mapping, Stockley wrote to du Toit asking his advice on various matters related to the geology, geomorphology and palaeontology of Basutoland. Their correspondence lasted until 1946. Stockley’s map and report on Basutoland geology laid the foundation for all future exploration and led to the discovery of several diamondiferous kimberlite pipes in the 1960s, and to the establishment of several diamond mines that contribute significantly to the economy of modern Lesotho.

Abstract:

Dr. August Tobler was a well-known Swiss geologist, who, as one of the very first petroleum field geologists in the Netherlands Indies, did more than ten years of geological mapping in the tiger-infested jungles of South Sumatra. He first worked for the Koninklijke/Royal Dutch and Moeara Enim oil companies in South Sumatra from 1900 to 1904. This was followed by six more years of geological mapping in the Jambi basin, as the first non-Dutch geoscientist at the Dienst van het Mijnwezen (Geological Survey). His thoroughly documented monographs and geologic maps of his geological fieldwork in the Palembang and Jambi basins of South Sumatra, as well as the adjacent Barisan Mountains, set new standards for quality and detail.Much of the personal information on Dr. Tobler is from papers by Kugler (1930, 1963), Oppenoorth (1930), Stehlin (1931) and Hottinger (2013). This paper is one of the chapters from a new book that is being prepared by the first author, entitled Pioneers and Milestones of Indonesian Geology (~1820-1960).

Abstract:

EMODnet Geology Project work package 6 collects information regarding ‘Geological events and probabilities’, including submarine landslides, earthquakes, volcanic centres, tsunamis, fluid emissions and tectonics. The elaboration of guidelines to compile GIS layers was aimed at identifying parameters to be used to thoroughly characterize each event. Particular attention has been devoted to the definition of the ‘Attribute tables’ in order to achieve the best degree of harmonization and standardization complying with the European INSPIRE Directive. Due to the different geological settings of European seas it was necessary to elaborate a comprehensive and detailed pattern of attributes for the different features, in order to represent each occurrence at different scales. The huge amount of data received has been processed, validated and standardized, thus obtaining homogeneous data layers at a European level. Metadata and available information collated during the project are displayed on the EMODnet Geology Portal (http://www.emodnet-geology.eu/). By combining all these data it may be possible to elaborate additional thematic maps which could support further research as well as land planning and management. The Geological Survey of Italy is testing one of these potential applications, which addresses the production of a structural model for submerged areas in Italy.Thematic collection: This article is part of the Mapping the Geology and Topography of the European Seas (EMODnet) collection available at: https://www.lyellcollection.org/cc/EMODnet

Abstract:

ABSTRACT As a young man, Henry Thomas De la Beche (1796–1855) participated in geology within elite gentlemanly societies. On field excursions—within England and beyond—he examined the natural landscape and recorded his observations in both narratives and illustrations. The origin of De la Beche’s geologic maps can be traced to 1821, when he mapped coastal France from St. Vaast to Fecamp; in 1822 he mapped south Pembrokeshire, Wales, using the recently published Ordnance maps (1:63,360). Of utmost importance to De la Beche was an accurate recording of factual observations in graphic form so that the maps would represent useful data in the future. De la Beche continued mapping in Jamaica (1824) and Devon’s Tor and Babbacombe bays (1827). In 1832, while mapping Devonshire, De la Beche’s personal finances worsened. He successfully petitioned the government to continue his mapping projects, proposing that his completed maps would be of national practical utility. Following the completed Devonshire maps, De la Beche leveraged the project to continue mapping other parts of the country. He became the first director of what would eventually develop into the British Geological Survey. In this position, De la Beche influenced mapping techniques while insisting upon consistency of results. Several men learned geological surveying under De la Beche and brought his methods to other countries. Since De la Beche selectively documented the geology he deemed important to observe, his geological maps serve as graphic data repositories of observations recorded during their construction. His surveying techniques also have enduring influence.

Abstract:

The development of innovative information technologies has improved the geological mapping process through the use of smart and portable equipment to collect field data, build a geological database and produce geological maps. This revolution has also brought great influence and challenges to practical training in field geology. In this paper, we present our workflow and application of the Digital Geological Survey System (DGSS) during field geology training for undergraduates in Zhoukoudian. The DGSS employs a Point-Routing-Boundary (PRB) model to reform the methods of geological section survey and geological mapping in terms of data collection and map-making and provides a pipelined solution from field data collection to map-making. The experiences of data collection, geological mapping, cross-section survey, and production of stratigraphic histograms and cross-section maps prove that DGSS can save time and reduce labor intensity for undergraduates during learning field geology. Based on the field practice of undergraduates in Zhoukoudian, the influence of the DGSS in promoting field geological teaching and the students’ feedbacks to DGSS are discussed. Overall, the DGM system is more popular than the conventional notebook and toolbox. The experience in Zhoukoudian proves that digital devices are efficient and useful for geological practical training of field geology for undergraduates.

Abstract:

AbstractInterest in environmental geological maps (EGMs) has increased in Britain since the publication in 1982 of the IGS Report 82/15 Environmental Geology of the Glenrothes District, Fife Region. Over the past decade or so similar interests have been developing elsewhere, particularly in the USA and in Europe. This review examines the style and purpose of EGMs in both the USA and Europe, and recognises distinct, yet different, characteristics in each. The review provides a reference against which British experience, when it is published, can be assessed.The US work, though very variable in style and scale of mapping, is consistently concerned to provide earth- science information to planners, engineers and politicians concerned with development, urban growth and redevelopment. The weakest of these studies provide raw geological data, the best make an effort to translate these data into terms that can be understood by the potential user.The European approach to EGMs has been different in that it tends to appear under the title ‘engineering geological maps’, and in some cases, such as under the ZERMOS scheme in France, has a direct relevance to the concept of Le Code de L’Urbanisme et de l’habitation (article R 128.18, 1970). In fact variations in style and purpose exist across Europe, with varying degrees of influence upon regulations or legislation in terms of planning and development.

Abstract:

The Atlantic Seaboard is an 18 km stretch of coastline located on the Cape Peninsula, South Africa, roughly between the Cape Town suburbs of Mouille Point in the north and Hout Bay in the south. It borders heavy shipping traffic and contains a mix of urban and natural environments including up-market seaside neighbourhoods and is part of the Table Mountain National Park. The predominantly rocky coastline has a northeast–southwest orientation with interspersed sandy pocket beaches. A narrow, low-lying coastal plain (marine terrace) in the north merges with coastal cliffs further south. The geomorphology and sedimentology of the coast are closely linked to the underlying geology, influencing the shape of coastal embayments and promontories, as well as the composition and distribution of sediment. Hydrographic, geophysical and sedimentological techniques were used to collect high-resolution bathymetry, seafloor geology and sediment distribution data to better understand modern coastal processes. The results indicate a low-relief seafloor consisting of Malmesbury Group rocks in the north. To the south the seafloor consists of high-relief Cape Granite reefs interspersed with fine to medium grain sand and bioclastic (shelly) gravel. Sediment transport is generally northward by longshore drift. In the south, the high-relief granite reef and headlands form sediment traps resulting in several large pocket beaches and offshore sediment deposits. In the north, the low-relief Malmesbury bedrock is largely free of sediment, except within narrow erosional gullies. Most sediment rapidly passes through to the north resulting in a sediment-starved rocky seafloor. The three principal sources of beach sand are aeolian fine sand transported by the Karbonkelberg headlands bypass dune entering the sea at Sandy Bay, biogenic carbonate production along the coast, and weathering of Table Mountain Group sandstone and granite bedrock. A fourth source is sediment entering the system via longshore drift from the south of Duiker Point. The water depth around the Duiker Point headland is presently too deep for sediment to be transported easily through longshore drift, other than during large storm events, but during past sea-level low stands this would have played an important part in supplying sediment to the coast. Changes in sea level play an important part in shaping the geomorphology of the coastline. Beach deposits, both sandy and boulder beaches have been left at various elevations along the coast, both offshore and onshore. Although today the Sea Point area is protected by sea walls and man-made structures, a higher sea level was responsible for shaping the narrow coastal plain. Increasing rates of global sea-level change are becoming an important issue all over the world and the Atlantic Seaboard coast is not immune to the effects of sea-level rise. The frequency and magnitude of storm events that breach the sea defences erode beaches and sea cliffs and cause damage to private and public property are likely to increase in the future

Abstract:

The greenstone belt of Kenya is an extension of what is commonly referred to as the Tanganyika "Shield". The two supracrustal sequences recognized in Kenya are the Nyanzian and the Kavirondian. The rocks found in these sequences are diverse, with dominant volcanics in the Nyanzian, whereas the Kavirondian is predominantly sedimentary. The Nyanzian lavas represent a diverse range from basalts and basaltic andesites, through andesites and dacites to rhyolites. From geochemical studies the basalts and basaltic andesites are tholeiitic, whereas the andesites, dacites and rhyolites are calc-alkaline. The sedimentary sequence ranges from mudstone, through shales, sandstones and grits to conglomerates. The plutonic rocks range in composition from gabbro to true granites, but tonalite is the dominant rock type. The chemical differences between the tholeiitic basalts and the calc-alkaline andesitic to rhyolitic sequences suggests that these volcanic suites are derived from different sources and/or through different processes. The granitoids have close chemical similarities with the silicic volcanics. From the geochemical and field relationships, the Nyanzian and Kavirondian sequences are considered to have developed on a continental segment which had not yet attained full stability. The model employed for the generation of these volcanics considers the basalts to have been generated in a region undergoing extension, similar to that of a modern back-arc environment, whereas the calc-alkaline sequences, including the granitoids, are broadly comparable with those found in present day continental arc environments.

Abstract:

Landsat Thematic Mapper, NSOOl Aircraft Thematic Mapper, Geoscan Mk. II. Multispectral Scanner and Airborne Gamma Radiometric data have been used to address a variety of geological problems in the Mary Kathleen area, 60 km east of Mt. Isa, NW Queensland. This area forms part of the Cloncurry Complex, a structurally complicated mass of diverse igneous and metamorphic rocks in the Precambrian Mt. Isa Inlier for which many stratigraphic problems remain to be solved. The Landsat Thematic Mapper data have been the most extensively used in this study. They are the least problematic data type and provide new geological information at scales up to 1:50 000. The NSOOl Aircraft Thematic Mapper data have similar spectral but superior spatial resolution in comparison with the satellite data. They suffer from increased geometric and noise-related problems, but the increase in spatial resolution has allowed the solution of problems, at scales up to 1:10 000, which could not be comprehensively addressed with the satellite data. The higher spectral resolution Geoscan Mk. II Multispectral Scanner aircraft data used in the latter part of the study can be used to remotely identify surface mineralogy. The logarithmic residual technique has proved the most successful approach to enhancing the radiance data sets. When applied to the lower spectral resolution data the technique achieves good discrimination of most lithologies, produces an albedo image useful for structural mapping and yields more information than can be extracted using conventional techniques. When applied to the higher spectral resolution data the technique allows remote mineral identification. Many of the geological problems in the area have been wholly or partially solved using suitably processed radiance data. The Airborne Gamma Radiometric data have the lowest spatial resolution. Only discrimination has been possible with this data set. These data contain no terrain information and are therefore difficult to use in the field. Integration of the gamma radiometric data with satellite data has been successful in overcoming this problem. The gamma radiometric data have allowed the separation of some lithologies which cannot be separated using the radiance data sets but have contrasting radiometric counts.

As part of the study, an analysis of methodologies used in engenheering geological mapping was made, with special emphasis on two lines of Brazilian methodologies, i.e., the procedures used by the Engineering School of São Carlos - University of São Paulo and by the Institute of Technological Researches of the State of São Paulo S.A. - IPT. The main purpose of the study is to apply the progressive detailing method to engineering geological maps in urban areas, with a view to produce more adequate instruments for urban administration and planning, taking into consideration the necessity of the users. The progressive detailing method's application was made in a 160 km2 area that included an urban site and urban expansion in the municipal district of Rio Claro, a medium size town of the state of São Paulo, Brazil. The progressive detailing method consists of adopting different approach scales in engineering geological mapping, with the study being divided into three successive stages, in levels of increasing detail, from general to specific. The first stage showed the importance of geologic and geomorphologic studies on the development of next stages. The quantification of some parameters on 2nd stage was of great value on characterization of the units of study. The completion of laboratories analysis on the 3rd stage to subsidy projects and buildings, is better evaluated if it is guided for previous stages.<br>Doutor

A realização de ensaios de laboratórios na 3ª etapa é melhor dimensionada quando orientada pelas fases anteriores, estudos estes, efetivamente aplicados, se direcionados a projetos e obras.<br>This paper's main theme is engineering geological mapping in urban areas, bringing together the results of the assembly, analysis and interpretation of geological data, as well as the cartographic representation of geotechnical units. As part of the study, an analysis of methodologies used in engenheering geological mapping was made, with special emphasis on two lines of Brazilian methodologies, i.e., the procedures used by the Engineering School of São Carlos - University of São Paulo and by the Institute of Technological Researches of the State of São Paulo S.A. - IPT. The main purpose of the study is to apply the progressive detailing method to engineering geological maps in urban areas, with a view to produce more adequate instruments for urban administration and planning, taking into consideration the necessity of the users. The progressive detailing method's application was made in a 160 km2 area that included an urban site and urban expansion in the municipal district of Rio Claro, a medium size town of the state of São Paulo, Brazil. The progressive detailing method consists of adopting different approach scales in engineering geological mapping, with the study being divided into three successive stages, in levels of increasing detail, from general to specific. The first stage showed the importance of geologic and geomorphologic studies on the development of next stages. The quantification of some parameters on 2nd stage was of great value on characterization of the units of study. The completion of laboratories analysis on the 3rd stage to subsidy projects and buildings, is better evaluated if it is guided for previous stages.

Full text

Abstract:

Abstract Managing pipeline integrity with respect to natural threats requires geoprofessionals to consider how the earth may behave into the future. Predicting morphological change involves a deep understanding of geology, geological processes, climate change, and knowledge of physical changes that have happened in the past or may occur in the future. One of the most capable techniques for mapping changing terrain through time across spatially extensive regions is lidar change detection (LCD) with airborne lidar scanning (ALS) data. LCD has typically been performed on a site-specific basis at known geohazard locations. However, with recent developments in data acquisition and processing, LCD is now a cost-effective tool that can be used on a systemwide scale to aid in the identification of potential geologic hazards and monitor known geohazard sites for active ground displacements that may be impactful to pipeline infrastructure. It enables monitoring of hazards directly impacting the right of way, as well as peripheral hazards that could encroach on the right of way. This proactive method of identifying and monitoring geohazards significantly enhances the ability of pipeline operators to make informed decisions and design resilient infrastructure. The work presented demonstrates how over 40,000 linear kilometers of LCD analysis was executed and integrated with a geohazard management program to support proactive decision-making across the eastern US.

Abstract:

Environment in which carbonate reservoir rocks are deposited was studied by visiting and collecting rock samples from a carbonate reservoir analog located at Jabal Fuwairit in the Northeastern coast of Qatar. The primary objective of this study is to develop methods to characterize carbonate reservoirs. The experimental procedure included collecting samples based on geology, mapping the location and altitudes of the samples using a high-resolution Global Positioning System (GPS) with an altimeter, permeability measurements at selected locations, conducting petrophysical measurements on the samples, Conventional and Micro-X-ray Computed Tomography Scanning (CT Scanning), Scanning Electron Microscopy (SEM), X-ray Energy Dispersive Spectroscopy (EDS) and Atomic Force Microscopy (AFM) imaging. It is observed that the permeability measurements show an alternating pattern as a function of height above sea level. The cyclicity is probably representative of repeating sequences of sea level changes over geological time. CT Scanner and Micro-CT Scanner measurements were employed to obtain vital information about the flow pathways in the rock, thus assisting in calculating the porosity to compare with values measured in the lab. SEM results gave direct visualization of the pore network and information about grain size (500 microns) and intergranular porosity, mineralogy, compared with the EDS results, and lithotype. EDS results showed that reservoir rocks directly exposed to environment had significant alteration due to weathering. However, it is encouraging to learn that samples even few inches away from the surface had minimal environmental influence.

Full text

Abstract:

Abstract Ultra-deep azimuthal electromagnetic (EM) logging-while-drilling (LWD) tools are frequently used during landing operations for early detection of the reservoir top. This enables alterations to the well plan before the reservoir is penetrated. To date, this approach has relied on one-dimensional (1-D) inversions that accounts only for changes in resistivity above or below the wellbore. When geology is complex, resulting in lateral changes in resistivity, 3-D inversion of EM data is required to provide increased reservoir understanding. This paper presents a case study from offshore Brazil, targeting a turbidite deposit. A complex reservoir surface was expected, as defined by seismic data for the area. Although top structure rugosity and lateral position uncertainty had been incorporated into the prognosis, the impact of surface topography on inversion results while landing was not anticipated. During real-time operations, 1-D EM inversion was used along with correlation of shallow LWD data to map the reservoir top. It was clear the geology was more complicated than depicted by the 2-D geological model constructed from the 1-D inversion and that lateral changes in surface morphology may be occurring. Post well a 3-D inversion of the EM data revealed the 3-D geological structure. During the initial approach, the 1-D inversion indicated that relief of the reservoir top was more exaggerated than expected; the well intersected a sharp peak prior to approaching the target zone. The misfit on the 1-D inversion indicated there was potential for lateral variation in resistivity, influencing the 1-D results; lateral changes can produce artefacts that obscure the subsurface structure. This was confirmed after drilling with analysis of ultra-deep azimuthal resistivity images, indicating significant changes in resistivity to the left and right of the borehole. A 3-D EM inversion was run to depict these complex subsurface geometries. The 1-D inversion results were better understood post-drill with the 3-D inversion results, which show a high point in the reservoir top to the side of the wellbore that was drilled past, but not penetrated by, the well. This high-resistivity zone had a negative effect on the 1-D inversion results and made delineation of the reservoir top difficult. Understanding lateral variations in formation and fluid boundaries can improve well placement and reservoir understanding. This knowledge can impact landing scenarios and well placement within the reservoir. Three-dimensional inversion of ultra-deep azimuthal EM LWD data in real time will provide a clearer picture of the position of resistivity changes while drilling. This will enable decisions to be made that affect the azimuthal position of a well, as well as its vertical position during drilling, thereby facilitating optimal well placement, even in complex geological environments or for infill wells requiring precise well placement.

Full text

Abstract:

New infrastructure corridors within the Slave Geological Province could provide transportation, electric, and communications links to mineral-rich areas of northern Canada, and connect southern highway systems and Arctic shipping routes. Relatively little information on permafrost and ground ice is available compared to other regions, particularly in the north of the corridor. Improved knowledge of permafrost and ground ice conditions is required to inform planning and management of infrastructure. Work within the Geological Survey of Canada's (GSC) GEM-GeoNorth program includes mapping periglacial terrain features, synthesizing existing permafrost and surficial data, and modelling ground ice conditions along the Yellowknife-Grays Bay corridor. Here we present initial modelling of ground ice abundance in the region using a methodology developed for the national scale Ground ice map of Canada (GIMC), and higher resolution surficial geology mapping. The results highlight the increased estimated abundance of potentially ice-rich deposits compared to the GIMC when using more detailed surficial geology as model inputs.

Abstract:

The Labrador Sea, Davis Strait, and Baffin Bay offshore regions, collectively referred to as the Labrador-Baffin Seaway, and their onshore margins including Baffin Island, Bylot Island, and West Greenland, form a region with a complex geological history developed through successive tectonic events. This complex geological and tectonic history is described in detail in this volume, a collaborative undertaking under the Geological Survey of Canada's Geo-mapping for Energy and Minerals 2 program (GEM-2), with contributions from external partners. Knowledge from pre-existing studies, essential contributions from collaborators, and GEM research results have been incorporated into the 14 papers contained in this volume, which summarize previous geological and geophysical knowledge and include novel insights from a regional perspective that serve as a guide for future research and exploration activities. The papers in the volume highlight both onshore and offshore studies in order to produce a comprehensive synopsis of the geological history of the region, with corresponding high-resolution reference maps and figures, and select GIS data sets. This compilation is divided into sections covering Precambrian and Paleozoic geology, Mesozoic to present geology, and resources within the region.

Abstract:

Geophysical data acquired under the Geological Survey of Canada's GEM Cordillera project provide a foundation to a broad range of geological investigations in the northern Canadian Cordillera. For areas of specific geological interest, over 230 000 km of high-resolution aeromagnetic data form a mosaic of comprehensive coverage over a total area of more than 82 000 km2. The data provide a powerful and valuable legacy data set for current and future activities by the Geological Survey of Canada and academic and industry partners and clients. Foremost, geophysical data interpretation complements surface geological mapping, especially in inaccessible terrain where bedrock exposure is commonly poor, enabling clearer definition of a region's geology and structure. Beyond applications to bedrock geological mapping, geophysical modelling, integrated with geological results, affords an improved understanding of the deeper crustal structure, leading to new models of the region's tectonic development and mineral deposit context.

Abstract:

The Geo-mapping for Energy and Minerals (GEM) program provided an opportunity to update bedrock geological maps for nearly 92 000 km2 of the northwestern portion of the mainland area of the Northwest Territories. Twenty-four new maps (at the scale of 1:100 000 or 1:250 000) cover a region from the Colville Hills southwestward into the Mackenzie Mountains, including areas of significant mineral and energy resource potential. New mapping was informed by archived Geological Survey of Canada data, notably from Operation Norman (1968-1970), as well as by public-domain industry data. Maps incorporate numerous stratigraphic revisions that postdate Operation Norman, including GEM program innovations affecting Neoproterozoic (specifically Tonian and Ediacaran), Cambrian, and Ordovician units. In this paper, the mapping effort and stratigraphic revisions are documented, a preliminary treatment of structural geology is provided, and related subsurface studies are summarized. Following GEM, GIS-enabled bedrock maps will be available for a swath of territory stretching from the edge of the Selwyn Basin, near the Yukon border, to the Brock Inlier in the northeastern portion of the mainland area of the Northwest Territories.

Full text

Abstract:

The geophysical data sets available for the western Churchill Province have had a bearing on the understanding of its structure, evolution and metal endowment. New data were acquired and interpreted during the Geo-mapping for Energy and Minerals (GEM) Program (2008-2020). Regional, high-resolution aeromagnetic, and targeted gravity and magnetotelluric surveys were collected in GEM, in conjunction with geological mapping projects, in order to provide control on bedrock features beneath widespread glacial overburden and flat-lying sedimentary basins. Quantitative estimates of three-dimensional geometry were obtained in key areas through geophysical models integrating the geophysical characteristics with local rock property measurements. These geophysical data sets contributed to new knowledge and interpretations in three related research fields: 1) location and nature of Rae cratonmp;gt;'s boundaries within the western Churchill Province; 2) definition of internal Rae architecture; and 3) identification of reactivated structures controlling gold and uranium mineralization. The new data, models and emerging tectonic and metallogenic frameworks will serve as guides for future exploration in this remote, complex, challenging region.

Full text

Abstract:

The new Grays Bay - Yellowknife corridor will provide transportation, energy, and telecommunications to northcentral Canada, and connect existing highway infrastructure to a deep-sea port on the Arctic Ocean. This infrastructure will improve access for exploration and development, and reduce operating costs in this mineral-rich region of the Northwest Territories and Nunavut, one of the biggest impediments to development in this region. Relatively little information on permafrost and ground ice conditions is available for most of the corridor. To fill this information gap, the Geological Survey of Canada's GEM-GeoNorth program is compiling permafrost and surficial geology information, mapping periglacial terrain features, and modelling ground ice conditions along the corridor. This poster presents the periglacial feature mapping component. Periglacial features are landforms associated with cold environments and typically contain permafrost. Permafrost, and its related ground ice, affect terrain sensitivity to climate change and surface disturbance. With development of this periglacial terrain and accelerated climate warming in the north, communities, planners, and regulators require this information to make informed decisions on how and where to build and manage environmentally sustainable and climate change-resilient infrastructure, and determine best adaptation strategies.
