Layer: Rock Geochemistry
This layer presents information on the location, sample, and analysis characteristics, and major element and trace geochemistry analytical results performed on rock samples in Washington State. This dataset includes analyses previously published by this agency, additional published and unpublished data. We opted to exclude U.S. Geological Survey (USGS) geochemical analyses for this compilationódata collected by the USGS is already compiled within the National Geochemistry Database (NGDB)(USGS, 2004).
This layer is part of a larger compilation of geochemical data for Washington State [geochemistry.gdb]. Trace analyses for samples can be viewed (if available) by selecting analysis locations with the Identify Tool, and then clicking on the plus sign (+) next to the analysis record in the left-hand pane of the Identify Features window; clicking on the plus sign will show a list of available trace element analyses, and clicking on an item in the list will display the results in the right-hand pane of the Identify Features window.
