Intrusion of granodioritic bodies into the lime stones of Ghorveh area led to the formation of calc-silicate marbles and various types of skarns. These skarns consist essentially of calcite, clinopyroxene, garnet, wolastonite, vesuvianite and epidote. Based on geochemical studies, garnets were identified as grossular and anderadite. The clinopyroxene found in the skarns is diopside. With respec...
