Deteri Gold Copper Deposit,located in at the west part of west Qinling metallogenic belt,is a typical skarn type deposit.Via 1∶10 000 geological preliminary survey,1∶10 000 soil profile,1∶2 000 rock profile and trenching,four mineralization belts were discovered in the study area,and 13 gold copper ore(mineralization) bodies were delineated.The study shows that the ore(mineralization) bodies mainly occur in the contact zone of Longwuhe Formation crystalline limestone and Indosinian granodiorite,and the Longwuhe Formation crystalline limestone,Indosinian granodiorite and the NW fault structure are the main ore-controlling factors.The contact zone of Longwuhe Formation crystalline limestone and Indosinian granodiorite,the NW fault structure and wall rock alteration such as skarnization,carbonatization,ferritization,malachitization and pyritization can be the main geological prospecting criteria.The soil anomalies dominated by Cu and Au element,followed by Li,As,Sb,W and Bi element combination can be the main geochemical prospecting criteria.
