Table S1: EMP analyses of Hiawatha melt grains, detrital minerals and EMP standards, and compositions of reference points shown in Figure 15; Figure S1: Felsic melt grain 21J-t03 with mordenite microspherulites and perlitic fractures; Figure S2: Felsic melt grain 21J-z40 with microspherulitic mordenite, fragments of quartz and plagioclase as well as perlitic fractures with hydrothermal alteration. Mordenite microspherulites mixed with Al-Si glass predominate.
