Relics of augitic clinopyroxene, albite, actinolite, chlorite, clinozoisite, and sphene. Relics of the clinopyroxene of the original dolerite are in part substituted by chlorite and actinolite in a granoblastic and metablastic matrix of albite,…
Grossular-andradite garnet, diopside, chlorite, sodic pyroxene, vesuvianite, titansphene, opaques. Traces of primitive gabbroid structure with diablastic development of the newlyformed phases and pseudomorphs of sodic pyroxene on primary pyroxenes.…
Antigorite, magnetite, carbonates (ankerite), diopside, clinohumite, tremolite, chlorite. Rarely, pseudomorphs on primary pyroxenes may be recognized, though there is superimposition of various deformational phases.
This sample is mis-labeled as a pegmatite. It is really a porphyritic dike material that cuts through the Zoroaster Granite. The phenocrysts are hornblende.
