Fabric Code: tpr341e

Sigatoka quartzose E

Low lithic quartzose fabric.

Fabric Class:

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

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.
