The occurrence of chromian edenite, confined to the degraded chromitite layers of the Sinduvalli ultramafic body is reported. Field, petrographic and chemical studies suggest that its development has occurred during the prograde metamorphism of the layered body. The enrichment of silicate phases in chrome-amphibole and chloritesis attributed to re-equilibration of chromite during the metamorphic episodes affecting the area and the formation of 'ferritchromit'.

Abstract


The occurrence of chromian edenite, confined to the degraded chromitite layers of the Sinduvalli ultramafic body is reported. Field, petrographic and chemical studies suggest that its development has occurred during the prograde metamorphism of the layered body. The enrichment of silicate phases in chrome-amphibole and chloritesis attributed to re-equilibration of chromite during the metamorphic episodes affecting the area and the formation of 'ferritchromit'.
