3-D Geologic Map Leads Precious Metal
2018/1/10
Using technology for 3-D electronic mapping originally developed by scientists working in the McMurdo Dry Valleys of Antarctica, NSF-funded researchers discovered one of the world's largest precious m...
Geologic time is shorthand for slow-paced. But new measurements from steep mountaintops in New Zealand shows that rock can transform into soil more than twice as fast as previously believed possible.

Oxidation State of Iron in Glauconite from Oxidized and Reduced Zones of Soil-Geologic Columns
Glauconite Iron Mossbauer spectroscopy Oxidized zone Pyrite Reduced zone Soil
2011/11/30
Abstract: Glauconite from the oxidized and reduced zones of soil-geologic columns at two Coastal Plain sites, one in Maryland and one in New Jersey, was examined by M鰏sbauer spectroscopy. The data ind...
Geologic structure and geochemical characteristics of sediments of fluoride and arsenic contaminated groundwater aquifer in Kalalanwala and its vicinity, Punjab, Pakistan
anthropogenic contamination groundwater aquifer aeolian sediment buried valley chlorite
2017/8/9
To constrain the origin of fluoride and arsenic contamination of groundwater in Kalalanwala, Punjab, Pakistan, the geochemical and mineralogical characteristics of the aquifer were studied. Subsurface...
The surface geology of Ford County in southwestern Kansas is featured on a new full-color map available from the Kansas Geological Survey, based at the University of Kansas.

Modeling Dielectric-constant Values of Geologic Materials:An Aid to Ground-penetrating Radar Data Collection and Interpretation
Dielectric-constant Values Geologic Materials Ground-penetrating Radar
2009/10/20
Ground-penetrating radar (GPR) is a near-surface geophysical imaging technique used for non-intrusive subsurface geologic and engineering investigations. Dielectric constant is a critical parameter fo...
Spatial variability of soil selenium as affected by geologic and pedogenic processes and its effect on ecosystem and human health
elenium spatial variability agricultural ecosystem human health
2017/8/9
Selenium (Se) deficiency and excess in agricultural ecosystems are related to many human health problems through the food chain and depend on the spatial variability and bioavailability of Se in soils...
Geologic Control of Severe Expansive Clay Damage to a Subdivision in the Pierre Shale, Southwest Denver Metropolitan Area, Colorado
Bentonites Expansive clays Pierre Shale Smectites
2011/12/27
Abstract: Shortly after construction of a subdivision in the southwest Denver metropolitan area in 1986, a portion of the subdivision built directly on steeply-dipping strata of the Pierre Shale began...
