in this study, principal components analysis was used to investigate lithological characteristics of jahani salt dome, firouzabad. the spectral curves of rocks in the study area show that the evaporate rocks have the highest reflectance at specified wavelengths. the highest reflection has been seen in gypsum and white salt, while minimal reflection can be observed in the igneous rocks from the ...

magnetic susceptibility has been extensively used to determine the magnetic properties of rocks for different applications, such as hydrocarbon or mineral explorations. this magnetic quantity can be directly measured in an accurate but time-consuming operation, or it can be mathematically approximated using a reliable procedure to achieve a desired accuracy. the poisson theory is one of the mos...

This report describes the preliminary re.wlts of surficial geological mapping during the 1992 field season in the Chilanko Forks (93Cil) and Chezacut 193CiX) map areas (Figure 4. IO-1 ). As part of the Canad;~ f3ritish Cofumhia Mineral Developme~~t Agreement, the British Columbia Geological Survey Rranch proposed to map the surlicial geology of these weiis to deriw drift exploration potential m...

The Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS) initiated a two-year regional pilot survey in 2007 to develop, test, and validate tools and approaches to assess the condition of northern Gulf of Mexico (GOM) coastal wetlands. Sampling sites were selected from estuarine and palustrine wetland areas with herbaceous, forested, and shrub/scrub habitats delineated by the ...

Liguria is a small region in Northwestern Italy which characterized by significant and valuable geoheritage. The 1:250,000 map presented this paper displays the 120 geosites of Liguria, officially approved regional national authorities, framed context geological landscapes region. were obtained categorizing thematizing geological, lithological geomorphological data macro-units with similar char...

Multi-scale geological models contain three-dimensional, spatially referenced data, typically spanning at least six orders of magnitude from outcrop to regional scale. A large number of different geological and geophysical data sources can be combined into a single model. Established 3D visualisation methods that are widely used in hydrocarbon exploration and production for sub-surface data hav...
