Abstract

Sarjangal area is located on the western margin of the Flysch Zone Eastern Iran and on the Eastern border of the Loote zone in the Southwest of Zahedan. In this area, there are mainly ophiolitic melange and rocks of the flysch facies. In this research, 1:25000 geological maps were first prepared with remote sensing studies and then completed and corrected using field and laboratory studies. In this area, the melange ophiolitic complex is composed of ultramafic, mafic, limestone and flysch rock units, which have a fault boundary with flysch complexes. The flysch-type units in western side are shale, sandstone, conglomerate, pyroclastic rocks and interlayers of limestone and igneous rocks and in the eastern side are metamorphosed flysch, shale, sandstone and limestone. The geological structures in the region are two types, a north-west trend as dominant trend and a north-east trend as accessory trend. The alterations occur mainly along shear zones in the study area. The shear zones prepare a permeable space for fluids to circulate. Manganese mineralization occurs in purple shale in the northwest of the area. Ophiolite mélange has the potential for mineralization of magnesium, chromium and copper.
