Mineral investigations and knowledge of their chemical composition are the fundamental facts in determining the deposit's economic potential. In the study field, different rock and mineral samples were collected including limestone (LS6, LS7, and LS8) and granitoids samples (S1, S2, S3, and S4). The detailed investigations reveal that the limestone samples are dominated by calcite associated with accessory minerals, the granitoid samples show high levels of silica minerals and some ultra-high metamorphism minerals of granulite facies. Based on [20] classifications of granitoid, the samples fall in the ferroan granitoid [Fe2O3 (t)/ (Fe2O3 (t) +MgO]. Modified Alkali-Lime Index (MALI) plotting [Na2O+K2O-CaO] against SiO2.
