Metallogenic Characteristic and Potential of Copper Polymetallic Deposits in Zhaohuduge Area of Chifeng City

The study area is located within the copper polymetallic metallogenic belt in the middle and southern part of the Greater Xing'an Mountains. The mineralization in this area has a genetic relationship with the subvolcanic intrusion in middle and late Yanshanian, with a mineralization age of 273~120Ma, which are mainly from the Late Jurassic to the Early Cretaceous. And most of these deposits belong to hydrothermal disseminated type. Through analyzing and studying the mineralization geological characteristics and metallogenic conditions of these deposits, the geological characteristics of regional mineral resources have been discussed in detail, and their metallogenic model has been established in this paper. The results show that the mineralization in this area has space-time and deep-source natures, with good mineralization alteration. The NE-trending fractured zone provides the ore-transmitting structure, while the sub-structure fractures and the interchanges of multi-group structural fractures serve as the ore-hosting structures. Volcanic hydrothermal fluid is ore-forming medium for the activation, migration and enrichment of mineralization minerals in crust. The results also show that this area has a good potential for mineralization.
