Olivine-bearing pyroxene-rich placer (plagioclase-poor).

Fabric Class:

Pyroxenic-Igneous: Dominated by pyroxenic and igneous lithic 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).
