Karobo quartzose

Moderately sorted, fine- to coarse-grained, subangular to subrounded quartz-bearing sand of heterogenous mineralogy and probable stream origin.

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.
