This child page contains qualitative multi-element compositional data from scanning electron microscopy-energy dispersive spectrometry. The data are in the form of element maps and normalized compositional data from spots or areas. These qualitative data are accompanied by backscattered electron images and, in some cases, corresponding optical images. Quantitative measurement of features in a subset of the optical images is also presented. Data collected after July 22, 2019 are subject to secondary data review as required by the Energy and Minerals Mission Area Quality Management System (EMMA QMS). As this process is not yet complete, data collected after July 22, 2019 must be considered preliminary or provisional (subject to revision). They are being provided to meet the need for timely best science. The data have not received final approval by the U.S. Geological Survey (USGS) and are provided on the condition that neither the USGS or the U.S. Government shall be held liable for any damages resulting from the authorized or unauthorized use of the data. When secondary data review is completed, this provisional statement will be removed.
