Abstract:

Alburnoides holciki was described from the Hari River basin, which was the only basin it was known from. Populations from the Amu Darya basin were previously recognized as A. eichwaldii or Alburnoides sp. Our study recognized specimens of Alburnoides from the Amu Darya basin as A. holciki based on morphological data and the COI barcode gene. The population from the Zeravshan basin showed some morphological differences compared to others but were similar in the COI gene and needs further investigation. New results extend the range of A. holciki for almost 1000 km from the Hari River to the upper Amu Darya tributaries in Tajikistan. The intraspecific genetic similarity in the COI gene between populations in the Hari and Amu Darya rivers supports the geographical hypothesis of a recent connection of these rivers.

Abstract:

The morphological dynamics of rivers are motivated by way of a number of things, including floodplain sedimentation, channel migration, sediment transport, and hydrodynamics. A considerable information of the complicated dynamics of river structures is important to layout river initiatives which can be sustainable and environmentally conscious. Implementing thorough river control plans that include hydraulic infrastructure and ecological restoration projects is important to overcoming these boundaries. This solution will effectively manipulate competing needs for water resources whilst ensuring the preservation of the location's herbal heritage. In the cease, this study affords essential new understandings of the complex interactions between hydrological patterns, human hobby, and geological procedures within the Amu Darya Basin. The application of sustainable land control and water useful resource making plans in Afghanistan might be appreciably impacted with the aid of those findings. Afghanistan has a lot of freshwaters because the Hindu Kush Mountains receive a significant quantity of precipitation. An estimated 75 billion cubic meters of potential water resources, consisting of 57 billion cubic meters of surface water and 18 billion cubic meters of groundwater, are found in Afghanistan. The Amu Darya, Northern River Basin, Helmand River Basin, Harirud-Marghab River Basin, and Kabul River Basin make up the Indus River Basin, which provides around two-thirds of Afghanistan's freshwater resources. All of Afghanistan's rivers, with the exception of the Northern River, flow across international borders into neighboring countries. The distribution of water from the Amu Darya River was subject to limitations imposed by the USSR, which was previously known as the Union of Soviet Socialist Republics. The majority of the water is used mostly for farming. Protocol 566, formally ratified by the former USSR, allowed the transfer of water from the Amu Darya River to the four Central Asian Republics (CARs) of Tajikistan, Uzbekistan, Turkmenistan, and the Kyrgyz Republic. By investigating the bodily functions of the basin, which includes land erosion and channel development, this looks at seeks to enhance our understanding of the landscape evolution of the basin. Our intention is to improve our information of the landforms, tectonic activity history, and the consequences of climate change inside the region by utilizing geological studies and facts from faraway sensing.

Abstract:

Amu Darya and its bank has a unique and surprising natural landscape. Green zone along the banks of the Amu Darya River extends throughout the river. Until the second half of the twentieth century, the region was in a natural state. In order to increase the area of irrigated agriculture in Central Asia, natural resources used irrationally without taking in consideration the consequences of this project and at the same time ecological state of the region constantly deteriorated. Floodplain forests and a variety types of plants, which are growing on the banks of the rivers of Central Asia are characterized by their specific ecosystem.

Abstract:

The flow of the Ile River is regulated by a cascade of reservoirs on the tributaries and along the river trunk: Bartogay ( Shelek River ), Kapshagay (Ile River), etc. The maximum flow rates along the Ile River are determined by the capa of the discharge structures of the hydroelectric power plants and the unregulated flow of the lateral inflow (Kaskelen River, etc.). The Ile River is formed by the confluence of the Tekes and Kunges Rivers, and it also receives a lot of tributaries, the sources of which flow down from the snowy peaks of the adjacent mountains. In terms of water content and turbidity, the water of the Ile River ranks third among the large rivers of Central Asia (Amu Darya, Syr Darya), and is only slightly inferior in water content to the Syr Darya River.

Abstract:

The Amu Darya River, a critical water resource for Central Asia, frequently becomes a focal point of tensions between Uzbekistan and Afghanistan. Recent discussions regarding the Amu Darya have been reignited following the construction of a canal by the Taliban administration in 2023. This research delves into the water-related issues between Uzbekistan and Afghanistan, with a particular emphasis on the significance of the Amu Darya River to the countries in the region. Adopting a historical perspective, this study systematically examines official reports, bilateral and multilateral agreements, and existing literature through comparative analysis. The findings suggest that cooperation and consensus at the bilateral level are paramount, overshadowing the contributions of regional and international organizations in resolving this issue.

Abstract:

The increase of irretrievable river water withdrawals and regulation of river flow has  a negative effect on the natural regime of the Aral Sea. The Amu Darya River and  the Syr Darya River Basins are the largest irrigated farming areas. This negatively  transforms the natural environment and worsens socio-economic conditions in Aral  Region as a whole, especially in the lower reaches of Amu Darya and Syr Darya,  where natural conditions are largely determined by the sea's impact. At present, this  causes desertification of the non-irrigated zone in the deltas, spreading to new areas  as the Aral Sea dries out. This rapid drying out and destruction of the Aral Sea has  led to a number of socio-economic, climatic and health related problems.

Abstract:

This research is devoted to the analysis of the dynamics of climate change in the Amu Darya river basin using the global climate model and observational data. And also, the purpose of the study is to scale down and correct the offset of the GCF and adaptation to the Amu Darya river basin and assess the dynamic climate change and its future predictions of the impact on the hydraulic structures of the Amu Darya river basin. The offset correction was carried out on the basis of data from open sources from the archives of the world meteorological organizations and the analysis performed for the next 100 years. The article analyzes the results of the regions affected by the climate [1] from the point of view of the reduction of water resources, the disappearance of glaciers, an increase in temperature, and a decrease in precipitation. An increase in temperature leads to a steady decrease in the area of large glaciers, while small glaciers gradually completely disappear and a change in the ratio of solid and liquid precipitation alternately, which leads to a reduction in snow cover and is also accompanied by degradation and melting of snow cover permafrost in high mountain areas. For future projections of glacier area and melt water release, glacier volume is required. Climate change affects the hydrological regime of the river; this process worsens the operational regime of hydraulic structures in the Amu Darya basin. Such changes in glaciation, snow cover, and permafrost negatively affect the change in river flow and its distribution and the ecological assessment of the quality of the environment. Therefore, the study of changes in climatic conditions in the region and the development of climate change scenarios for the XXI century is carried out following the recommendations of the IPCC using the necessary programs.

Abstract:

Given the characteristics of significant or enormous resources, a wide range, many reservoir types, and challenging exploration on the right bank of the Amu Darya River, we systematically studied the characteristics of its reservoirs. Based on the core description, thin sections in combination with logging and seismic facies characteristics as well as regional tectonic-sedimentary background, the Callovian-Oxfordian platform and the gentle slope sedimentary system in the Amu Darya Basin of Turkmenistan were summarized. Sedimentary subfacies such as evaporation platform, restricted platform, open platform, and platform margin reef are developed in block A and its west. In contrast, the upper slope, lower slope, and basin sedimentary subfacies are developed in the east of block A. On this basis, the main reservoir types on the right bank of the Amu Darya River are summarized, namely, porous reservoir, vuggy reservoir, fractured-porous reservoir, and fractured-vuggy reservoir. After describing the characteristics of various reservoirs in detail, the main controlling factors, development patterns, and distribution rules of the development of different reservoirs are summarized. Specifically, based on the platform reef, the porous reservoir and vuggy reservoirs are developed mainly on the concealed palaeouplift in the study area and are greatly influenced by atmospheric freshwater leaching and buried dissolution. Based on the dominant sedimentary facies, the fractured-porous reservoirs are mainly developed in the central areas on the right bank of the Amu Darya River. In the later period, hydrothermal fluid and hydrocarbon-generating acidic fluid can dissolve the reservoir through strike-slip faults and their associated fractures. Diagenetic fluid enters the reef through faults and associated fractures to form dissolved reservoir bodies of a certain scale. The fractured-vuggy reservoirs are mainly controlled by faults and dissolution and are mainly developed near the eastern thrust fault on the right bank of the Amu Darya River, effectively guiding the direction for further exploration and development in this area.

Abstract:

The increasing global air temperature will trigger changes in the global mean water vapor, precipitation patterns and evapotranspiration, which further leads to changes, for instance, instream flow, groundwater flow and soil moisture. Projections of future changes in thehydrological regime of the Aral Sea Drainage Basin (ASDB) in Central Asia are however highlyuncertain, due to complexities of natural and engineered water systems of the basin. The AmuDarya River Delta (ADRD) is vital to the water budget of the Large Aral Sea, the livelihood inUzbekistan and Turkmenistan, as well as the surrounding riparian ecosystem. This study attemptsto investigate responses of river flow in the Aral Sea Drainage Basin and key riparian vegetationspecies (of the so-called Tugai community) in the Amu Darya River Delta to projected futureclimate change. Results from hydrological model and outputs from multi-GCM predictions providea basis for conducting more robust quantitative analysis of possible future hydro-climatic changesin the Amu Darya River Basin. A qualitative synthesis of the suitability of Tugai is furthermoreperformed in order to increase the knowledge of the riparian vegetation status under thechanging hydro-climatic conditions. The results show that the averaged temperature in the ASDBis likely to continuously increase and yield a total increase of about 2 °C ~ 5°C by 2100. Thechange trend of the annual regional precipitation of 2100 is relatively unclear, with estimatesranging from 50 mm lower than today to 75 mm higher than today. Modeled ensemble means (EM)river flow, obtained from hydrological modeling of climate output from multi-GCM projections,converge on showing future decreases in river runoff (R). Projected absolute R may decrease tozero around 2100, implying no surface flow and a dry out near the river outlet. The relationship ofwater flux between upstream and downstream will be changed dramatically due to climatechange. More specifically, R of the upstream region will decrease, and it is likely to becomeinsufficient for feeding downstream river reaches as it used to. The decreased river flow in thedelta may accelerate the desertification and salinization processes. Consequently, speciestransitions may occur, along with degradations of the existing Tugai communities. Theuncertainties of hydro-climatic change projections to some extent hinder the understanding of thedynamic hydrological-climatic-ecological system. However, the detailed responses of the delta toclimate change based on multiple qualitative and quantitative analyses provide an important basisfor the formulation of more robust forecasts on the future ecological development in the ADRD, and further for recommendations of measures to mitigate the ecosystem’s deterioration under achanging climate.

Abstract:

The wandering river pattern represents one of the last remaining river patterns that are not well understood. Many aspects of these rivers are not well known, particularly the processes of their creation and maintenance. The term wandering describes gravel or cobble bedded rivers, transitional between braided and meandering, with multiple channel sections around semi-permanent islands connected by single channel sections. This dissertation investigates the controls on the characteristics of wandering rivers within the Miramichi region of New Brunswick through time and at three nested spatial scales.<br>At the scale of rivers, three factors appear to be needed for wandering to occur: (1) wide valleys, (2) channel energy between braiding and meandering, and (3) avulsion triggers, frequent overbank flows caused by icejams in the Miramichi. Principal component analysis showed that larger wandering rivers displayed greater anabranching intensity than smaller rivers, perhaps related to higher stage ice jams within larger rivers.<br>At the scale of channels, the wandering pattern of the Renous River was found to be in a state of dynamic equilibrium, with channel creation balanced by channel abandonment. The anabranch cycle model was developed to illustrate the temporal dynamics of anabranch creation, maintenance and abandonment within wandering rivers.<br>Also at the channel scale, principal component analysis of channel reaches within the Renous River displayed differences in grain size and hydraulic efficiency between side-channels and main-channels. Energy and sediment mobility within side-channels was related to their formation, maintenance and abandonment. Energy and sediment mobility within main-channels was related to mega bedforms called bedwaves. The apex of some bedwaves occurred at diffluences.<br>At the scale of channel elements, diffluences are stable where a large bar is formed and accretes upstream, creating a large reservoir of sediment upstream of anabranch channels to buffer their degradation. Where diffluences are unstable, a large bar forms within one anabranch channel to partially block flow and may cause its abandonment. The dissertation illustrates that within wandering rivers, processes occurring at multiple spatial and temporal scales interact to create and maintain the pattern.

Abstract:

The complementary discourse explores the function and value of narrative and why mankind seems to have always seen events, connected or unconnected, as stories. It investigates how we process and perceive fiction and compares narratives found in non-fiction, police witness statements, films and diaries to consider why the human brain seems hard-wired to transform events into narrative. The accompanying novel, A River, is set in Manchester over a three hundred year period. The events in the chapters are presented in reverse order; from the 1990's to the 1720's, beginning with the chronological end of the tale and working towards the starting point. The chapter's regression highlights how a familiar location is constantly in flux and sometimes shares little with the same place of the past. Time and location are both treated as characters, playing important roles in the personality of the city. The buildings and streets, events, food and language have all been researched for accuracy, either first hand or using diaries, films, maps and photographs. The novel occupies a grey area between fiction and history. The narrative actively avoids the traditional novel formulas of historical fiction and magic realism and is intended to be an accessible experimental novel, questioning the idea of what a story is.

Full text

Abstract:

Development of the shallow alluvial groundwater of the Hadejia-Jama'are-Yobe River valley flood plain (northern Nigeria) has been taking place with increasing intensity over the past decade. However little has previously been known about the nature of the Yobe River-aquifer interaction, including the recharge mechanisms. This thesis reports on a study of the river-aquifer interaction in the middle section of the basin, centred on a field site near Gashua, Yobe State. Detailed field studies were undertaken over a period of 14-months, which involved geoelectical sounding, drilling and water level monitoring. The results of the field study show that the Yobe basin is underlain by a sand and gravel aquifer, which is covered by an average of 1-3m of clay. The Yobe River is in hydraulic continuity with the adjacent alluvial aquifer and variations in aquifer storativity have been recognised as an important factor in understanding the hydraulic behaviour of the Yobe River-alluvial groundwater system. A confinedunconfined groundwater regime exists within the present site and is an inherent characteristic of the alluvial groundwater system. The recognition of this state enables a conceptual flow model of the system to be developed. A multi-layer, spatially distributed model is proposed, in which transitions between confined and unconfined conditions can be realistically represented. A numerical model needs to be designed with these concepts in mind in order to simulate the system. The research techniques employed in the study are appropriate for the assessment of the Yobe basin system where detailed data is currently not available. The combination of detailed geophysical survey, water level monitoring and conceptual modelling has led to a good understanding of the Yobe River-alluvial aquifer interaction. It is for this reason that the techniques employed in this study can be adapted for investigating the remainder of the basin downstream of the present site.

Full text

Abstract:

Data for ten chemical parameters, obtained from the routine chemical monitoring programme for 49 sites in the Foyle River catchment, were assessed for temporal trends. Results suggest: A downward trend in dissolved oxygen concentration (%DO) at a majority of sites; An indication of a widespread upward trend in nitrate concentration; Evidence that increases in nitrate concentration occur a sites after rainfall following dry periods; No corresponding upward trend in Biochemical Oxygen Demand (BOD); Eutrophication as the main water-quality problem in the Foyle River catchment. Biological and chemical General Quality Assessment of the Foyle River sites classifies only 7 sites to the same classification band. Ordination of 10 sites was carried out using the seasonal averages of BOD, %DO, and NH4-N for each site and repeated using Spring, Summer and Autumn macroinvertebrate abundance data. Spearman Rank correlation suggests that BOD, %DO, and NH4-N have little influence in structuring the community composition at the sites. Comparison of species and family-level ordinations appears to support family-level identification in a monitoring programme although species of the same family show different correlations to the determinants. Family-based scoring may not reflect the complexes of species level responses to these variables. Multivariate analysis indicates that some pollution-sensitive species are correlated with greater than average BOD concentration. The removal of such species results in an increase of 3.1% in the % variance in the Spring data explained by the three variables, while Autumn is unchanged. The variance of the species-based data and the family-based ‘explained’ by the three variables in each season is essentially unchanged. Recalculation of Ecological Quality Indices (EQIs) for the 10 sites after these species are removed indicates that the number of sites classified to the same band is increased.

Abstract:

Abstract Dreissena polymorpha (zebra mussel), was introduced to the Great Lakes in 1986 and is now in Lakes St Clair, Erie, Michigan and Ontario and the St Lawrence River with isolated populations in Lakes Huron and Superior. Its planktonic "veliger" larva is dispersed on water currents and adults, by human and natural vectors. It has recently invaded portions of the Illinois, upper Mississippi, lower Ohio, lower Tennessee, Mohawk, Seneca, Hudson and Susquehanna Rivers and Lakes Oneida, Cayuga, and Seneca. Veligers settle in raw water systems and grow to adults. Attached by byssal threads to hard surfaces, adult mussels form thick encrusting layers which impede flow, increase sedimentation and aggravate corrosion. Settlement occurs where flow is &lt;1.5-2.0 m/sec. Reproduction ceases below 12°C (54°F) and veliger development is impaired above 26-27°C (79-81°F). These thermal limits suggest that zebra mussels could invade southern Canada and most of the US except for southwestern and southern states where summer water temperatures rise above critical levels for veliger development. Water quality, hydrological and geographic parameters such as stream size, fluctuation in water level, pH, O2 concentration, temperature, hardness, alkalinity, calcium content, limited runoff from rainfall, and high silt loads may prevent mussels from invading specific raw water sources.

Abstract:

The geography of human cercariasis is extensive. It covers urbanized areas of many modern metropolitan cities. Cercariasis is also known in the inland waters of the Amu Darya and Zarafshan River basins (within Uzbekistan). The causative agents of cercariasis consist of two clearly differentiated cercariae groups: Schistosoma and Bilharziella. The article presents the results of field and experimental studies on nonspecific human cercariasis caused by cercariae Schistosoma turkestanicum and Trichobilharzia ocellata in various reservoirs of Uzbekistan. In this paper, the studies were conducted in Uzbekistan in 2020–2022. The material was collected in the delta and floodplain reservoirs of the Amu Darya and Zarafshan rivers. The material was collected in the deltaic and bottomland water bodies of the Amu Darya and Zarafshan Rivers which were intensively visited by water birds and mammals. In different seasons of the year, spring, summer, and autumn, more than 25 thousand specimens of freshwater mollusks belonging to the families Lymnaeidae, Planorbidae, Physidae and Thiaridae were collected and studied. Morphological study of cercariae was conducted. In different types of reservoirs, the population of mollusks, intermediate hosts, of discussed trematodes, turned out to be quite high. Their total infection with parthenita and the cercariae bilharzia ranged from 0.3 to 6.2% in Lymnaeidae, and 4.0% in Melanoididae. Schistosome larvae (Sch. turkestanicum) infection was only recorded in Lymnaea auricularia (Lymnaeidae), which was 12.6 to 22.6%.

Abstract:

The Amu Darya River is a transboundary river whose flow of the river in high-water years reaches up to 108 km3 and in low-water years up to 47 km3 and these are huge fluctuations in the water flow of the river for Tajikistan, Kyrgyzstan, Uzbekistan, Turkmenistan, and Afghanistan, that share water among themselves. The point to consider is that the downstream countries Turkmenistan and Uzbekistan (and possibly Afghanistan in the future) use a lot of water for irrigation, and therefore these countries are the ones most in need of an accurate forecast of the volume of water for the upcoming season. An accurate forecast of the volume of water on the seasonal scale is necessary for better planning of the structure of crops, and subsequently water use in the irrigation of crops. An acceptable solution to this challenge is the construction of an empirical time series model that will be used to predict the seasonal flows of the Amu Darya River to improve the planning and management of water resources in downstream countries. This article considers three important discharge time series in the larger Amu Darya Basin. These include the Kerki Gauge on the Amu Darya, Darband Gauge on Vaksh River and Khorog Gauge on Gunt River. Long-term time series from these stations are available for the study of the development and implementation of time-series based models for the prediction of discharge in the basin. At this stage, we attempt to demonstrate a proof-of-concept which can in a second step convince stakeholders to share such type of discharge data operationally for more effective water allocation between sectors and countries. All our work was carried out with the quantitative tools R/RStudio and QGIS. It can serve as a stepping stone for more complex forecasting models in the future.

Abstract:

The river source of plastic debris to the southern North Sea region appears to be increasing over the past several decades, with a strong seasonal control on riverine MP transport and discharge. The current cruise, AL586, links plastic pollution in the North Sea to seasonal studies in the Elbe and Thames rivers as part of the H2020 LABPLAS project, with the objective to understand the transport and fate of river-derived small micro- and nanoplastics (SMNPs) in the North Sea. The specific objectives of the North Sea Plastics I & II cruises (the current cruise AL586 and planned cruise AL596) form a framework for mapping the distribution of microplastics and their associated chemical contaminants in the coastal southern North Sea and assessing spatial and temporal variation in the delivery and fate of these land-derived pollutants. Cruise AL586 sampled four primary and two intermediate stations between the Elbe and Thames river estuaries. Primary stations included CTD casts to collect discrete water samples between surface and seafloor, “snow catcher” sampling to collect settling aggregates, sediment sampling with Van Veen grab, suspended particle and plankton sampling using a vertical WP2 net, surface neusten sampling using a catamaran trawl, and sea surface microlayer sampling by Garrett screen. Intermediate stations were sampled only by catamaran net. Additional sampling along the cruise track included surface water sample collection from the ship’s underway seawater supply, and during calm weather, floating litter surveys to count the abundance of floating debris.

Full text

Abstract:

This study assesses the geothermal potential of Hot Sedimentary Aquifers underlying the Horn River Basin (HRB) based on analyses of borehole temperatures, geological and production data, core porosity and permeability measurements, and geophysical well logs. The proposed criteria are applied to evaluate the geothermal potential of the Horn River Group (HRG) and sub-HRG formations. Favourable spots are identified and ranked by applying temperature, thickness, porosity, permeability and flow rate mapping. The results show that the HRG and its underlying strata have a good potential of geothermal energy resource. Among the HRG formations with an average temperature of 110°C, the Otter Park Formation is the hottest and relatively thick with high water production rate. The Muskwa Formation is the second favourable for geothermal resource potential. Within the sub-HRGs, the Slave Point Formation is the most advantageous because of the high flow rate and high temperature, while the Keg River Formation is the hottest and thickest, and is considered as the second favorable stratigraphic unit. Combining the geological and geographical characteristics, four favourable hot zones have been identified, further indicating that the northwest Zone 1 and the southeast Zone 4 are the hottest areas with thicker reservoirs (&amp;gt;300m) and higher temperatures &amp;gt;130°C (at depth &amp;gt;3 km).

Paleoredox and lithogeochemical indicators of the environment of formation and genesis of the Monster River hyper-enriched black shale showing, Yukon. Natural Resources Canada/CMSS/Information Management, 2022. http://dx.doi.org/10.4095/328004.

Full text

Abstract:

Northern Yukon hosts occurrences of Middle Devonian hyper-enriched black shale (HEBS) Ni-Mo-Zn-platinum-group element-Au-Re mineralization, including the Monster River showing in the Ogilvie Mountains. This mineralization has been documented predominantly in the Paleozoic Richardson trough; however, the Monster River showing is atypical, occurring within the Blackstone trough, more than 200 km to the west on the southern margin of the Yukon block. The ambient paleoredox conditions of the marine water column and sediments may be primary controlling factors in HEBS formation. We use major and trace element lithogeochemistry to better understand ambient paleoenvironmental redox conditions through the application of robust redox proxies to HEBS mineralization and host rocks. Uniformly negative Ce anomalies (0.6-0.9) indicate that the water column was predominantly suboxic throughout the deposition interval, even during HEBS mineralization. Although there is a strong terrigenous influence on the rare earth element-yttrium (REE-Y) abundances of the sedimentary rocks, superchondritic Y/Ho ratios (&amp;gt;27) indicate that seawater contributed REE-Y to the host rocks and HEBS. High (&amp;gt;10) authigenic Mo/U ratios indicate that a Fe-Mn particulate shuttle operated in the water column; this is corroborated by negative Ce anomalies and high Y/Ho ratios. The data indicate that metalliferous sedimentary rocks formed by hydrogenous metal enrichment (e.g. Ni, Mo, Pt) caused by ferromanganese oxyhydroxide particulate shuttling as chemical sediments; moreover, the REE- and Mo-based paleoenvironmental indicators suggest a complexly redox-stratified depositional environment with an abundant supply of metals, metalloids, and sulfur.

Abstract:

Relevant geospatial data layers are required for developing next generation ecological response models for specific reaches of 5 rivers in Central Texas: Colorado, Concho, San Saba, Llano, and Pedernales Rivers. Therefore, a collaborative effort between Engineer Research and Development Center (ERDC), Texas State University, and Texas A&M University was undertaken to acquire and curate a collection of biological and physical datasets to be utilized as inputs for next generation ecological response models at various spatial scales (watershed, river buffer, and point). The objective was to aggregate and process GIS and remote sensing data layers using advanced geospatial analytics to generate relevant metrics (e.g., landcover, elevation, soil erodibility). Next, subsets of the priority datasets were extracted based on two spatial units of interest (local buffer and watershed). The priorities include (1) Percent land use and land cover information from National Land Cover Dataset (NLCD) land use/land cover class types (forest, cultivated land, open water, etc.) and soil composition (%); LU change, (2) Geomorphology for each sampling point, (3) Physiographic information on each sampling point, and (4) Linear stream distance between sampling points (5 Secondary) Distance/network analyses. This work was funded through ERDC’s Next Generation Ecological Modeling Program under the work unit titled, “Remote Sensing and statistical support for multi-scale field-based data collection”.

Full text

Abstract:

Polymetallic (Ni-Mo-Zn-Pt-Pd-Au-Re) hyper-enriched black shales in the northern Canadian Cordillera consist of thin, semi-massive sulfides interbedded with black shale. We studied HEBS deposits at Nick, Peel River, Monster River, and Moss in northern Yukon, and at a single locality underlying the Cardiac Creek Pb-Zn-Ag deposit in northeastern British Columbia. High-grade mineralization contains up to 7.4 weight per cent Ni, 2.7 weight per cent Zn, 0.38 weight per cent Mo, 400 ppb Pt, 250 ppb Pd, 160 ppb Au, and 58.5 ppm Re. Sulfide mineralization formed during syngenesis to later diagenesis. Analyses by LA-ICP-MS indicate that pyrite is the principal host of platinum-group elements, Au, and Re. Mineralization and sedimentation were coeval based on the overlap between Re-Os geochronology of HEBS at Nick and Peel River (390.7 ± 5.1 and 387.3 ± 4.4 Ma, respectively) and conodont biostratigraphic ages of sedimentary host rocks. Bulk S isotope composition of HEBS is uniformly negative, indicating that bacterial reduction of seawater sulfate generated sulfur to precipitate sulfide minerals. The initial Os ratios at Peel River (0.25 ± 0.07) and Nick (0.32 ± 0.20) overlap with Middle Devonian seawater, suggesting that elemental enrichment was derived from seawater.
