Asset Overview

This quartzo-feldspathic gneiss is an S-tectonite (it has a foliation, but no lineation). Quartz, plagioclase and alkali feldspar (probably orthoclase) dominate the rock and are accompanied by minor biotite. Possible protoliths include granite, felsic volcanics, or even a lithic sandstone.
