Kadavu western pyroxenic

From the Western Kadavu pyroxenic andesites. Some orthopyroxene present with the clinopyroxene.

Fabric Class:

Calcareous-Feldspathic: Dominated by calcareous and feldspar 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).
