HCA applied to identify processes controlling water geochemistry shallow aquifer system outer plains Jammu and Kashmir State. has good agreement hydro chemical facies reflect process pattern flow geological formation it explains di...

agh darreh tailing dam located in 23 km north of takab, west azarbayjan province is used for disposal of mine tailings. the tailing dam and its reservoir were constructed on gypsiferous marlstones. this is emphasis on geotechnical and environmental importance of the site. although construction of dams on gypsum rocks were not yet prohibited, but the dissolution of gypsum in contact with water i...

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 ...

Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value should be considered as geological heritage and, co...

The objective of this chapter is to provide an overview and discussion of the relevancy of various physical and chemical processes to be associated with the geological storage of CO2 at a particular site, and thereby serve as a bridge between the detailed process descriptions and modeling techniques to be presented in the following chapters and the studying and simulation of site-specific physi...

Travertine deposits are a kind of continental carbonates that form in specific chemical, physical and biological conditions. Garab travertines in southeast of Mashhad are studied based on field, geochemistry (elemental and stable isotope analysis) and hydro-geochemistry analysis. Field and petrographic characterization led to recognize of crystalline crust, raft, foam, shrub, laminated, black m...

Surface geological and geochemical mapping have been key technical contributors to many gold discoveries over the past 25 years. However, in the last ten years there has been a growing emphasis on using geophysical techniques to compliment them in covered terrains. As the search for gold deposits under covered areas expands, there will be increasing emphasis on integrating the geoscientific dis...

The quantitative measurement of surface roughness of planetary surfaces at all scales provides insights into geological processes. Complementary of the analysis of local topographic data of the Martian surface at kilometer scale, as achieved from the Mars Orbiter Laser Altimeter (MOLA) data, and at the sub-centimeter scale using photometric properties derived from multi-angular observations, a ...
