Fabric Code: tpr221

Erromango feldspathic non-placer

Plagioclase-rich non-placer temper, any calcareous grains appear to be reworked limeclasts, rather than modern reef detritus.

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).
