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...
These tables contain geochemical data collected for tephra samples either correlated with or in the same type section with the Ibex Hollow Tuff. Most samples were collected by Andrei Sarna-Wojcicki and Mike Perkins, but some were submitted to the U.S. Geological Survey Tephrochronology Project for analysis by other persons. Electron microprobe analysis (EMA) was performed at the U.S. Geological Survey in Menlo Park California, at the University of Utah in Salt Lake City Utah, and at the University of Toronto in Toronto Ontario Canada. Bulk glass EMA results have been normalized to 100% anhydrous following standard normalization procedures. Individual shard analyses are unnormalized. Instrumental neutron activation...
