Text Description: Tricuspate and platy shards, thick-walled pumice and some frothy pumice. Major and mineral minerals: plagioclase and orthopyroxene. Trace minerals: clinopyroxene, apatite, pyrrhotite, Fe-Ti oxides. Rhyolite component is crystal-poor (i.e. ~ 2% by volume) References:  Late Pleistocene and Holocene tephrostratigraphy of interior Alaska and Yukon: Key beds and chronologies over the past 30,000 years |
