Summary

This data set compiles the major and trace element chemistry of rock samples collected by the U.S. Geological Survey (USGS) at Bokan Mountain, located in the southern part of Prince of Wales Island, southeastern Alaska. Bokan Mountain was formed by an Early Jurassic peralkaline igneous complex that intruded into lower Paleozoic rocks of the Alexander terrane of southeast Alaska. The pluton and surrounding country rocks host numerous mineral deposits and occurrences, including heavy rare earth element (HREE)-rich pegmatites and felsic dikes, as well as mineral deposits rich in uranium, thorium, HREE, and fluorine. The Ross-Adams mine on Bokan Mountain exploited a uranium-thorium deposit intermittently from the late 1950s to 1971, and [...]

Purpose

This data set is a compilation of geochemical data from analyses of rock samples collected by the U.S. Geological Survey from mineralized and unmineralized rock of the Early Jurassic-age Bokan Mountain peralkaline granitic complex on Prince of Wales Island, southeastern Alaska. This pluton contains a variety of mineral deposits, exploration prospects, and mineral occurrences, with enrichments in the rare earth elements, thorium, and uranium. This data set is provided to help facilitate geologic mapping, petrologic studies, mineral resource assessments, the determination of geochemical baseline values and statistics, and environmental impact assessments related to the potential development of its mineral resources, in addition to geologic studies of many purposes.
