The study amphibolites are located in Hashtbandi village (east of Minab). The Makran amphibolites form a part of the metamorphic rocks of northern Makran ophiolitic belt, which are found in massive and orientated forms. Based on the indicator minerals, these rocks include amphibolite, epidote-garnet amphibolite and garnet-pyroxene amphibolite. Their main minerals include amphibole, garnet, plagioclase, pyroxene, epidote, quartz and sphene. Based on mineral chemistry, clinopyroxene in the epidote-garnet amphibolite and garnet-pyroxene amphibolite is calcic type and mostly in the diopside range. The studied pyroxenes are mostly magmatic and enriched in Si and are placed in the context of sub-alkaline rocks (tholeiitic and calc-alkaline). These clinopyroxenes are related to volcanic arc and based on the temperature-pressure calculations of pyroxenes, the temperature range is between 1070 to 1130 C and the pressure is 5 to 10 kbar, which indicates the crystallization of these minerals at high temperature and medium-high pressure. Also, based on the amount of ferric ion in clinopyroxenes, it indicates the low oxygen fugacity of formation environment.
