Solok Selatan is already known as an area that has potential precious metal, Gold. Local mining scale can be found on site certain areas in Abai Region, especially the North, which was previously believed to exist presence of these minerals. Based consideration associated mineral associations gold, course other metals deserves further investigation such Copper (Cu), Silver (Ag), Lead (Pb), Zinc...

Shallow earth translational slides and earth flows, affecting colluvial soils derived by the weathering of the clayey bedrock, are a recurrent problem causing damage to buildings and roads in many areas of Apennines. The susceptibility assessment, e.g. slope stability models, requires the preliminary characterization of these superficial covers (lithology, geotechnical and hydraulic parameters)...

A stochastic Bayesian approach for combining well logs and geophysical surveys for enhancing subsurface characterization is presented. The main challenge we face is in creating the bridge to link between ambiguously related geophysical surveys and well data. The second challenge is imposed by the disparity between the scale of the geophysical survey and the scale of the well logs. Our approach ...

This was a study of subglacial deformation till genesis from a modern temperate glacier, at Sk alafellsj€ okull, Iceland. Detailed microscale properties of till samples (from Scanning Electron Microscope [SEM] and thin section analysis) were examined from a glacial site with in situ subglacial process monitoring and an exposed subglacial surface in the foreland. Two lithofacies were examined, a...

Morphometric analysis is used to understand the hydrological process and assessment of characteristics surface water basin. In present paper, an attempt has been made study detail morphometric Kulbera Daurighara river basin, which are tributaries Subarnarekha River in Purulia district, West Bengal. For detailed study, SRTM data for preparing digital elevation model (DEM), Geographic Information...

This study presents an overview about the arsenic (As) contamination and its sources in two European countries. Arsenic is a highly toxic element inorganic form it carcinogenic to human seven low concentrations. The occurrence of As surface water, stream marine waters, groundwater, bottled sediment, soil, mines, seafood, environmental origin, impacts on health are discussed. classes Geoaccumula...

The geology of the DRC has already been studied on regional plans, scale a province or territory. But these studies are too synthetic and they do not consider variations petrographic facies that can occur at locality village. Thus, to overcome this possibility, present study aims make characterization rocks Mabuku in territory Beni. To achieve this, we proceeded by microscopic analysis 10 field...

Among many approaches been made to improve interpretation of post stack seismic section, a great effort has been made aimed at increasing the resolution power of interpreting section and mapping the seismic reflection data to lithology. The purpose of sparse spike impedance inversion is aimed at this goal, to obtain a high-resolution impedance profile from low resolution or band limited seismic...

Drill cuttings are considered representative of the lithology being drilled in a wellbore. However, the fragments that are two to three times larger and/or having odd shapes compared to the regular cuttings are commonly understood as cavings from the wall of the borehole and they are seldom of any help in compilation of a lithology. In fact, cutting description manual recommends ignoring cuttin...
