Roviana quartzose

Quartose. Plagioclase and quartz, clinopyroxene and opaques, some olivine.

Fabric Class:

Feldspathic-Quartzose: Dominated by feldspar and quartz inclusions.

Dissected Orogen: Dominated by plutonic lithics such as microgranite, and those with microphaneritic textures, as well as metavolcanics. They have K-feldspars dominate, in addition to plagioclase.
