This table contains geochemical data collected for whole-rock samples from the Columbia River Basalt Group in the western Columbia River Gorge in Oregon and Washington. Most samples were collected by Russell C. Evarts and Richard M. Conrey from 2002 to 2014. Samples were collected during traverses along roads, streams, ridgecrests, and other areas as part of ongoing geologic mapping. Additional samples were provided by Marvin H. Beeson. Major- and trace-element analyses were performed by X-ray fluorescence at the Peter Hooper GeoAnalytical Laboratory at Washington State University in Pullman, Washington. No normalization has been applied to these data.
This data release contains analytical data and images for a suite of drill core samples from the Mineral Hill alkaline complex (MHAC), northeastern Wyoming. Geochemistry data include major and trace element analytical results for 103 alkaline igneous rock samples. Images include hand sample photographs of halved core and full thin section images captured in transmitted, plane-polarized and cross-polarized light. Samples are from two core holes drilled by Humble Oil Company in 1970, and subsequently acquired and stored by Felix Mutschler at Eastern Washington University. The two skeletonized (incomplete) drill cores were acquired by the U.S. Geological Survey Geology, Minerals, Energy, and Geophysics Spokane office...
This data release contains macro and microscale datasets describing the abundance, valence states, and mineral residence(s) of chromium, iron, and manganese in natural and synthetic mineral mixtures used in laboratory experiments designed to simulate dynamic conditions in an engineered aquifer system [see Izbicki and Groover (2018) and Miller and others (2020)]. The landing page contains primary metadata about this release and an overview "sample information" table containing descriptions of samples, their analyses, and their methods of preparation and preservation. As there is not a one-to-one correlation between samples and types of analyses performed, the overview table is an important navigation tool to locate...
