Fabric Code: tpr134

TLTF olivine placer

Well sorted and subrounded to subangular pyroxenic temper sands from beach placers. Subordinate but significant olivine grains, dominant volcanic rock fragments are basaltic. Hyalopilitic rock fragments. Clinopyroxene dominant, but minor orthopyroxene.

Fabric Class:

Pyroxenic: Dominated by pyroxenic inclusions.

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

Sites:

Ceramic Wares

Transitional Far Western (2350 - 1900 BP)

Early Far Western Lapita (3500 - 2770 BP)
