>Appendix1_Geochemistry: Whole-rock, major-oxide XRF, and trace-element XRF and ICP-MS analyses of whole-rock samples and sediments rich in hydrothermally altered material from Chiginagak volcano (normalized to 100% without volatiles; all Fe converted to FeOT; original analytical totals given in the "Total-majors" column). Major oxides are reported as weight percent oxide, and trace elements are reported in parts per million (ppm). Also included are samples taken by J. Riehle and E. Yount (published in the Alaska Geochemical Database [Granitto and others, 2013]). Riehle and Yount samples with bold, italicized location information are those for which we have determined that the location provided in Granitto and others (2013) is incorrect (see notes in Location Description field for these samples).
>Appendix2_ArAr: 40Ar/39Ar age dating information for Chiginagak lavas.
