Molataleb region is situated in the north of Aligudarz and in the immediate vicinity of the Zagros Thrust Fault. Because of the activities of reverse faults and the Zagros Fault, Precambrian, Upper Precambrian - Lower Cambrian, Triassic and Jurassic Metamorphic Complex have been exposed. The effects of various metamorphic phases of different episodes, can be observed on these rocks. Following the Laramian Orogeny, the intrusive granitoid mass, affected the metamorphic rocks of the region. Lithological composition is mainly composed of granite, granodiorite and monzogranite. Mineralogical, lithological, and geochemical studies along with field observation indicate that the Molataleb Granitoid mass is of " S Type " and palingenetic granitoids. The tectonic discrimination diagrams showed that the granitoid mass is of post - orogenic Type. Additionally, regarding the geochemical affinities with other granitoids of adjacent (Borujerd, Hamadan, Buin- Mianadasht and others), They have been injected after the Laramian orogeny.
