Major Oxide and Trace Element Analyses for Igneous Rock Samples From South-Central Idaho

Digital Analytical Data (DAD): DAD-6

Reed S. Lewis
Thor H. Kiilsgaard

The file presents whole-rock chemistry, locations, and lithology of 350 igneous rock samples collected from 1978 through 1990. Most samples are from Cretaceous and Eocene plutonic rocks. All were collected by Thor Kiilsgaard, Reed Lewis, and field assistants during the Challis and Hailey CUSMAP (Conterminous U.S. Mineral Appraisal Program) projects of the U.S. Geological Survey. Only a subset of the data was previously published, and those data did not have precise locations. The data are sorted first by the year collected and then by the sample number. Analyses were completed at U.S. Geological Survey laboratories in Denver, Colorado, and Jeddah, Saudi Arabia, as well as at Washington State University and Franklin and Marshall University. Data are compiled in an Excel spreadsheet, version 9.0.x, and released as a WinZip file. Available only as a download. A metadata file is included in Acrobat Reader (PDF) format.
