Ambon-Haruku rhyolite

Rhyolitic temper sand-feldspar and quartz mineral grains, glassy volcanic rock fragments (mostly colorless), and subordinate biotite flakes.

Fabric Class:

Lithic Quartzose-Feldspathic: Dominated by igneous and/or sedimentary lithics, with quartz and feldspar.

Andesitic Arc Quartzose Variant: Dominated by andesite and basalt lithic fragments, with microlitic, felsitic and vitric textures, and the andesite minerals (plagioclase, clinopyroxene and sometimes hornblende). With quartz.
