Sodic pyroxene, glaucophane, lawsonite, chlorite. Pseudomorphs of sodic pyroxene and glaucophane,chlorite on original augitic pyroxenes; pseudomorphs of lawsonite and glaucophane on original plagioclase.
Carbonates (calcite and dolomite), chlorites, garnets, diopside, epidote, serpentine, amphiboles. Very variable compositions in same hand specimen. The rock derives from metamorphism of oficalcitic rocks developed at very high pressures and medium…
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,…
