Myanmar has a drier sub-tropical climate than countries that typically contain Ni laterite deposits, but hosts deposit at Tagaung Taung. Given enrichment processes in the Taung are poorly understood, we investigated geochemical and mineralogical evolution of two weathering profiles developed on different bedrocks central part Myanmar: partly serpentinized harzburgite an almost completely perido...

Quantifying bedrock weathering rates under diverse climate conditions is essential to understanding timescales of landscape evolution. Yet, are often difficult constrain, and associating a weathered landform specific formative environment can be complicated by overprinting successive processes temporally varying climate. In this study, we investigate three sites between 59°N 69°N along the Norw...

The Yanqi Basin is a coal-bearing basin in Western China. In order to determine the hydrocarbon generation potential of Jurassic source rocks this area, organic matter composition coal-measure mudstone, carbonaceous mudstone and coal rocks, yields liquid gaseous hydrocarbons, comparison sources were studied by means hydrocarbon-generating thermal simulation experiments. results showed that micr...

The present study applies a geophysical approach to the Federal district of Brazil, challenging hydrogeologic setting that requires improved investigation enhance groundwater prospecting meet rising water demand. characterization complex hard-rock aquifer sub-system was conducted using direct current (DC) electrical resistivity tomography (ERT) integrated with surface geological information. Wi...

The association of free Fe oxides with soils and clays from two Enon sandy loam (Ultic Hapludalfs, fine, mixed, thermic) soil saprolite profiles was studied. Goethite was the dominant Fe oxide identified. Lepidocrocite was detected in trace amounts in some sam ples. Fe/clay ratios were highest in the epipedons of these soils suggesting the concentrating of Fe oxides as a result of alumino silic...

The town of Teresina, in the state Piauí, Brazil, presents a history land sinking processes. Two events deserve to be highlighted, first occurred 1999 at Simplício Mendes Street and other on July 31, 2008, Francisco Street. To identify possible shallow caves associated structures, Geological Survey Brazil/CPRM developed Ground Penetrating Radar (GPR) study verify occurrence reflection patterns ...
