Several igneous-evaporitic rocks complexes, belonging to Lower Cambrian, are exposed in High Zagros. These rocks exposed parallel to the Zagros main thrust as diapir-shaped bodies. Basaltic rocks are the most common rocks but microgabbro, microdiorite, andesite and trachyte are the rocks of this complex. The studied clinopyroxenes are usually fresh mafic mineral in these rocks and display sector zoning features. On the base of mineralogy and mineral chemistry, the pyroxenes are in the range of titan-augite to diopside composition. The geochemical study of the clinopyroxene as well as the discrimination diagrams were used in this study, point to the transitional to alkaline nature of magmatism which occurredv in a within continental plate rift environment.
