Pidia modern

Modern Pidia sherd. Moderately sorted, fine- to medium-grained, subangular to subrounded temper sand. Clinopyroxene as dominant ferromagnesian silicate. Minor orthopyroxene.

Fabric Class:

Pyroxenic Amphibolic: Dominated by pyroxenic inclusions with amphiboles.

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:
