Sample Type 2:Dike
Text Description:
Large dike 10 to 15 meters wide east of Lava Peak. In hand specimen, it is coarsely porphyritic, containing large clinopyroxene and plagioclase phenocrysts in a fine-grained groundmass. In thin section, the dike contains the same mineral assemblage as the Lava Peak flows; randomly oriented phenocrysts of olivine, clinopyroxene, and plagioclase in a groundmass of opaque minerals, clinopyroxene, and plagioclase laths.
