The Midcontinent region of the United States is part of the cratonic platform of the North American craton. This region is underlain by Precambrian basement formed dominantly during Proterozoic accretionary orogenies. ...

Although many investigators have described factors responsible for the formation of calcium carbonate (CaCO3) in natural systems, quantifying the extent to which biological influences drive precipitation in carbonate ...

Volcanic activity may lead to potential volcanic eruptions, but it also provides critical information for understanding the physical processes within a volcanic system. Combining multiple observations and advanced physical ...

Molecular dynamics (MD) computational modeling studies of the structure, dynamics and energetics of water at surfaces and in nano-confined spaces provide greatly increased, atomistically detailed understanding of the effects ...

ABSTRACT We tested an in situ method for monitoring the concentrations of aqueous chemical species and dissolved gases in groundwater. We deployed in situ samplers in 8 wells completed in the glacial Glasford formation ...
