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

This file provides analysis of whole-rock chemistry, sample locations, and lithology on over 550 igneous and metamorphic rock samples collected from 1989 through 2005. Most of the samples are from the Idaho batholith, Challis plutonic and volcanic rocks, the Belt Supergroup, and amphibolite-facies metamorphic units. Data were compiled in an Excel spreadsheet, version 9.0.x, and downloaded here as a WinZip file. Available only as a download. A metadata file is included in Acrobat Reader (PDF) format.
