Through the analysis of the metallogenic geological background and main geological characteristics of the ore bodies in the Nyakaber gold mining area in Tanzania,the main geological characteristics and metallogenic factors of the gold mineralization bodies in the mining area are roughly understood.The gold mineralization in the Nyakaber gold mining area is controlled by the northwest-trending ductile shear zone,and occurs in the diorite body in the form of veins or lenses.The mineralization degree of the banded iron formation zone is low and only partially mineralized.The ore type is mainly altered rock type,with widespread pyritization and local silicification.The ore minerals are natural gold.According to the analysis of the main metallogenic geological characteristics of the ore-controlling structures,ore-bearing rock layers,and mineralization and alteration intensity in the mining area,the degree of gold mineralization in the Nyakaber gold mining area is low,and the prospecting prospects are generally average.
