Biogenic carbonates are valuable archives of paleoenvironmental information because they record chemical signatures of ambient environmental conditions during their formation. Therefore, long-term records of biogenic ...

Surface mining of steelmaking coal in the Elk Valley, British Columbia, Canada, has resulted in the release of constituents of interest, such as selenium (Se) and nitrate (NO3-). Oxidation of sulfide minerals in the ...

Elevated concentrations of molybdenum (Mo) in groundwater are a growing concern at mines worldwide. However, information on geochemical controls of Mo mobility within mining environments are limited. Sorption onto Fe(III) ...

It has been well established through various experimental and numerical studies that imposing an external shear on a system of partial melt will result in the compaction of the solid matrix and expulsion of the interstitial ...

Dissolved gases including methane (CH4), ethane (C2H6), and propane (C3H8) are natural components of groundwater. Knowledge of the origin, distribution, and fate of these gases is crucial for assessing the impacts of oil ...

This study investigates the mineralogy and geochemistry of natural aquifer materials associated with a uranium (U) ore deposit at the Smith Ranch-Highlands Mine, Wyoming, USA. The ore occurs in a roll front deposit and is ...

The Williston Basin is one of a number of North American intracratonic basins whose subsidence is poorly understood. The Basin is circular in shape and contains nearly 5 km of preserved sedimentary rocks at its center; ...

Recent episodes of extreme weather and the drastic consequences they can have for ecosystems, societies, and economies, emphasize the need for a better understanding of Earth’s climate. In order to gain a better understanding ...

The origin of tourmaline nodules, bizarre spherical to irregular textures documented worldwide, remains a geologic mystery. Although previously described by numerous researchers, the physical and chemical parameters that ...

The stable isotope and chemical compositions of water samples from several Upper Cretaceous and Quaternary aquifers in Saskatchewan were measured to determine the source of recharge within the individual aquifers and the ...
