Geochemical major-oxide, minor-oxide, trace-element, and rare-earth-element data from rocks and streams sediments collected in 2012 in the Ray Mountains area, Beaver, Bettles, Livengood, and Tanana quadrangles, Alaska

Mineral-resources personnel from the Alaska Division of Geological & Geophysical Surveys (DGGS) carried out a helicopter-supported geological and geochemical resource assessment project in the Beaver, Bettles, Livengood, and Tanana quadrangles from June 23 through August 5, 2012. The objectives of DGGS's resource assessment are to improve the trace-element geochemical coverage of selected watersheds; to obtain modern, quantitative geochemical analyses; to understand the petrogenesis of the granites; and to better document established mineral occurrences. Stream-sediment, pan-concentrate, and rock sampling were conducted as part of the State's Rare Earth Elements and Strategic Minerals Assessment project, which is...

Data on barium, strontium, cobalt, and nickel plumes formed during microbial iron-reduction on sediments and in water from a crude-oil-contaminated aquifer, Bemidji, Minnesota (2009-2019)

This U.S. Geological Survey (USGS) Data Release provides concentrations from groundwater and soil extracts for iron (Fe), barium (Ba), strontium (Sr), cobalt (Co), and nickel (Ni). Groundwater analyses for pH and alkalinity are also included. Samples were collected at the National Crude Oil Spill Fate and Natural Attenuation Research Site, near Bemidji MN (USA) between 2009-2019. The site is in Beltrami County, where a high-pressure pipeline carrying crude oil burst in 1979 and spilled approximately 1.7 million liters (10,700 barrels) into glacial outwash deposits. A trace element plume occurred at the site, in which concentrations of Fe, Co, Ni, Ba, and Sr were mobilized from the sediments into the groundwater....
