Fabric Code: tpr178

Bismarck pyroxenic

Moderately sorted, subangular to subrounded aggregates that are probably stream sands. Hyalopilitic microlitics.

Fabric Class:

Pyroxenic Amphibolic: Dominated by pyroxenic inclusions with amphiboles.

Postarc: Clinopyroxenes, plagioclase, and lithics of basalts or shoshonite (a basaltic trachyandesite), dominate.

Sites:

Ceramic Wares

Transitional Far Western (2350 - 1900 BP)
