Fabric Code: tpr195

Watom hybrid

Hybrid calcareous with plagioclase and augite, opaques and rock fragments (pale brown vitric glass) and andesitic arc.

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).
