Major Oxide and Trace Element Analyses for Igneous and Metamorphic Rock Samples From Northern Idaho

Digital Analytical Data (DAD): DAD-13

Reed S. Lewis
Richard M. Gaschnig

This file includes analyses of whole-rock chemistry, sample locations, and lithology on 65 igneous and metamorphic rock samples collected from 2003 through 2010. Most of the samples are from Cretaceous and Eocene plutonic bodies and amphibolite-facies metamorphic units and the majority were collected to support geologic mapping efforts for the U.S. Geological Survey STATEMAP Program in the Sandpoint and Bonners Ferry 30'x60' quadrangles. The data are sorted by year collected and then sample number. Data are compiled in an Excel spreadsheet, and distributed as a WinZip file. Available only as a download.
