Chert geochemistry discriminant analysis and K-meas cluster analysis: Rampart Project area, Tanana B-1 Quadrangle, east-central Alaska

A pilot study using discriminant analysis on major oxide and minor element data from 67 chert samples in the Rampart area, southeastern Tanana and southwest Livengood Quadrangles, western Yukon-Tanana Upland, Alaska, generally indicates a unique geochemical signature for the cherts of a given unit.Chert samples from five known type locales were used as standards of comparison: 1)Livengood Dome Chert (Ordovician), 2)Amy Creek unit (Proterozoic to early Paleozoic), 3)Rampart Group (Mississippian to Triassic), 4)Troublesome Creek unit (Devonian), and 5)Permian-Triassic clastic unit (associated with the Triassic-dated gabbro). Samples from the above units were compared to chert from Tanana B-1 area-units of unknown...

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....

Strontium Concentrations in Fish from the Davis Pond Freshwater Postdiversion Sampling (2007-2009) with a Comparison to Prediversion Levels (2001)

The diversion of freshwater from the Mississippi River is intended to mitigate saltwater intrusion from the Gulf of Mexico and to lessen the concomitant loss of wetland areas. Though effective, freshwater diversion can affect wildlife and habitat; therefore, prediversion and postdiversion data collections are necessary to identify effects. The Davis Pond freshwater diversion area is located between the Mississippi River and Bayou Lafourche and extends to Barataria Bay Basin, Louisiana. Results and interpretations from the prediversion biomonitoring done in 2001- which included data on fish, eagles, and bivalves - are presented in the U.S. Geological Survey (USGS) Scientific Investigations Report 2008-5067, "Davis...

Strontium isotope record of paleohydrology and continental weathering, Eocene Green River Formation, Wyoming

Sr isotope ratios in carbonate-rich lacustrine strata provide highly resolved and geographically specific records of past changes in weathering and regional drainage patterns. The Eocene Green River Formation is perhaps the best documented pre-Quaternary lacustrine unit in the world; therefore, these strata are ideally suited for studying the behavior of Sr. The 87Sr/86Sr ratios measured for primary carbonate in lake expansion- contraction cycles of the Laney Member are directly linked to changing lake facies. Four distinct cycles are preserved in a 6.4 m interval of the Arco Washakie Basin No. 1 core, each represented by a vertical succession of transgressive stromatolite facies containing dolomicritic intraclasts,...

Strontium isotope ratios of lavas from Kīlauea Volcano, Hawaiʻi

Strontium isotope ratios of historical Kīlauea summit and rift lavas were analyzed by thermal ionization mass spectrometry (TIMS) at the Southwest Isotope Research Laboratories of the U.S. Geological Survey (USGS) in Denver. There were 151 analyses of 49 samples obtained from the field, the collections of the USGS Hawaiian Volcano Observatory (HVO), and the Smithsonian Institution. Data for associated reference materials are described in the process steps . The Sr isotope ratios may be used to test models for the volcano’s magmatic plumbing system.
