sample_remark Roberts et al 2006 paraphrased "A pink rhyodacite lava containing scattered medium to coarse (up to 4 mm) phenocrysts (10%) of plagioclase, rare quartz and biotite, fine-grained, irregular accumulations of chalcedony and opaque minerals. The groundmass has fine, slender, felted plagioclase laths and small irregular areas of chalcedony. Uppermost part with foliated, contorted and broken folds. Foliation in the folds varies from fine to coarse (up to 4 mm thick), the bands being delineated by accumulations of thin or globular pumice fragments or accumulations of opaque minerals overlain by fibrous crystals of zeolite and chlorite."
