Text Description: Sample of a columnar, dense flow of chrysophyric hyalobasanite. The phenocrysts are fresh, euhedral olivine crystals. The groundmass consists of a brownish glass in a state of devitrification containing small grains of olivine, augite, plagioclase, and magnetite. Many secondary growths of chalcedony and zeolite occur throughout the glass. References: ![]() |
