Abstract:

Aim of the Study: Two main geologic terrains of basement complex and sedimentary areas were investigated for underground water production capacity by evaluating the aquifer properties. The assessment was done by evaluating 19 boreholes in the two terrains. TK1-TK10 constituted the boreholes from basement area, while AK1-9 constituted boreholes of sedimentary terrain. Methodology: Pumping rate of the boreholes were crucial to establish the water production capacity from the geologic terrains.

Abstract:

Abstract Tesserae on Venus are locally the stratigraphically oldest units preserved on the planet. These regions are characterized by pervasive tectonic deformation including normal faults, grabens, thrust faults, and folds. In multiple tesserae, sets of (often highly) curved, parallel linear features are also present. These features strongly resemble terracing in layered volcanic or sedimentary sequences on Earth having arcuate or sinuous outcrop patterns that follow undulating topography. Should this analogy hold for Venus, then these outcrop patterns imply some erosion of the tessera units

Abstract:

The underground sedimentary bauxite ore body in Shanxi province has a shallow burial depth; the valley terrain caused stress concentration on a pillar which affected the pillar’s safety and goaf stability. This paper proposed a pillar safety coefficient calculation method affected by the goaf structural parameters and the valley terrain, which was based on a pillar mechanics analysis under the valley terrain. The results show that the overlying valley terrain will cause stress concentration on the pillar, reducing the adequate bearing capacity and the pillar stability. The increase of the goaf

Soil depth is a crucial parameter in slope stability analysis in mountainous areas.

Gangwon-Do, a predominantly mountainous region in South Korea, is selected as the study target area.

Abstract:

Glacial ripping is a newly recognized process sequence in which subglacial erosion is triggered by groundwater overpressure. Investigations in gneiss terrain in lowland Sweden indicate that ripping involves three stages of (i) hydraulic jacking, (ii) rock disruption under subglacial traction, and (iii) glacial transport of rock blocks. Evidence for each stage includes, respectively, dilated fractures with sediment fills, disintegrated roches moutonnées, and boulder spreads. Here, we ask: can glacial ripping also occur in sedimentary rocks, and, if so, what are its effects? The case study area

Abstract:

In the past, the term “terra rossa” became quite a common indication for all limestone derived red soils in the Mediterranean region. Today, in some classification systems based on the Mediterranean climate as the major soil differentiating criterion, the term terra rossa is used as a name for the soil subclass “Modal Fersiallitic Red soil” when situated on limestones (DUCHAUFOUR, 1982). However, several national soil classifications (e.g. Croatian, Italian, Israeli) retained the term “terra rossa” for the hard limestone derived red soils. The nature and relationship of terra rossa to underlyi

Abstract:

We have used high-resolution geophysical data to investigate depositional and erosional bedforms in two geomorphologic provinces of the deepwater central Gulf of Mexico Basin: (1) the Mad Dog and Atlantis areas in the Sigsbee Escarpment region and (2) the Holstein minibasin within the salt canopy in the slope. Multibeam bathymetry indicates that the seafloor relief in the study areas is highly irregular because it is influenced by the dynamic behavior of underlying salt bodies resulting in the development of diverse bathymetric features. Side-scan images reveal erosional furrows of different m

In this study, we investigate the crustal velocity structure and Moho discontinuity depth beneath the NE Iran continental collision zone through joint inversion of P receiver function and Rayleigh wave group velocity dispersion curves. Local Rayleigh wave group velocity dispersion curves were estimated using time-frequency analysis method and two-dimensional surface wave tomography method. Our results distinctly highlight prominent changes in velocity structure along both the northern and southern flanks of Daruneh fault, occurring at both the crustal and lithospheric scales.

AbstractAn accumulation terrace close to the El'gygytgyn Impact Crater in northeastern Siberia contains stratigraphic and periglacial evidence of the paleoenvironmental and paleoclimatic history and permafrost dynamics during late Quaternary time. A succession of paleo active-layer deposits that mirror environmental changes records periods favorable for the establishment and growth of ice-wedge polygonal networks and sediment variations. These two elements of the periglacial landscape serve as complementary paleoenvironmental archives that can be traced back to ∼ 14,000 cal yr BP. The slope se

ABSTRACT Exploration for gold in Nunavut has been primarily focused on Archean greenstone belts in the north and coastal regions of the territory, resulting in large areas of underexplored terrain in the south. The Kiyuk Lake property is located in the underexplored southwest corner of the Kivalliq Region of Nunavut within the Hearne domain of the ∼1.9 Ga western Churchill Province. The property is hosted by Proterozoic calc-silicate and clastic sedimentary units of the Hurwitz Group (&lt;2.4–1.9 Ga) and the unconformably overlying Kiyuk Group (1.9–1.83 Ga).

A cost-effective and non-intrusive aeromagnetic geophysical technique was utilized to reduce exploration uncertainty in the Chad Basin, which is believed to have significant hydrocarbon potential despite limited exploration due to its remote and challenging terrain. By analyzing various derivatives and magnetic attributes extracted from filtered and enhanced aeromagnetic data, the study aimed to highlight potential areas for hydrocarbon generation and preservation, allowing for more focused and detailed geophysical exploration efforts.

Hydrochemical investigation of forty boreholes drilled on the basement and sedimentary rocks in Ibadan and Lagos metropolis southwestern Nigeria respectively were carried out in order to determine the portability of the groundwater in both areas and to highlight differences in their chemical characters and variations with seasons. Data obtained indicated that the groundwater in Ibadan area is mainly the Na + Ca – HCO3type, while that of Lagos is Na + Ca – C1 + SO4 type. The groundwater chemistry reflects weathering of sodic plagioclase feldspars in the basement rocks as well as arkosic sands

The objective of this feasibility study was to determine if the seismic reflection method could help to optimize placement of water‐quality monitoring wells near a radioactive storage facility. Seismic reflections from depths less than 30 m were recorded along a 500 m long line over a basalt, rhyolite, and sedimentary sequence in the Snake River Plain. Some shallow reflections at 40 to 50 ms on the field files are of exceptional quality with frequency exceeding 150 Hz. Reflections and refractions from selected seismograms along the line possess vastly different normal‐moveout (NMO) and apparen

Sediments are described in 51 outcrops and characterized by grain size composition. The outcrops revealed complete or incomplete sequences of the general scheme from bottom to top: sandy tidal–coastal units overlain by gravel- and cobble-rich fluvi

The research area is located in the Northern part of the Karelian Isthmus between Lake Ladoga and the Gulf of Finland of the Baltic Sea. The terrain features are closely related to the tectonic structure of the crystalline basement, partially covered with thin deposition layer of the Last Glaciation and Holocene mostly. Accumulative forms are rarely but strongly correlated with the tectonic structure also. Most expressive features of accumulative topography are esker ridges that stretch for tens of kilometers. Analysis of eskers spatial distribution shows their close connection with the struct
