Fabric Code: tpr173

Taumako pyroxenic placer

Better sorted but no more rounded placer black sand formed by intensive reworking of volcanic debris. Clinopyroxene grains, plagioclase feldspars, and volcanic rock fragments.

Fabric Class:

Pyroxenic: Dominated by pyroxenic inclusions.

Andesitic Arc: Dominated by andesite and basalt lithic fragments, with microlitic, felsitic and vitric textures, and the andesite minerals (plagioclase, clinopyroxene and sometimes hornblende).

Sites:

Ceramic Wares

Late Lapita Solomons (2700 - 1800 BP)
