Fabric Code: tpr88

Northcoast PNG type D

Type D, Abundant moderately sorted and subangular quartzofeldspathic non-placer temper sand. Clinopyroxene and orthopyroxene present.

Fabric Class:

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

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.
