Metallogenic regularity and ore-prospecting orientation of the Taoxi circular area

Abstract: With more than 50 deposits and favorable ore-forming conditions, the Taoxi circular area is an ore concentration area for copper and polymetallic deposits. The deposits and geochemical anomaly as well as geophysical field show circular shape, and the main metallogenic and ore-controlling factors for the deposits in the area are a favorite assemblage of metallogenic and ore-controlling structures as well as the magmatic rocks of Mesozoic magmatic activity in the late Yanshanian period; all these phenomena are also the important prospecting criteria. The main kind of the deposits is porphyry or magmatic hydrotermal type. The circular places are the targets of further copper and polymetallic ore exploration, and particularly more attention should be paid to the volcanic craters or well-developed porphyry areas or ore spots situated in the volcanic depression.
