摘要
Located in Dandong City, Liaoning Province, Sidaogou gold deposit is of medium-temperature hydrothermal type, mainly occurs in the meta-sandstone strata of Liaohe Group of Early Proterozoic era, and is genetically related to the intermediate-felsic magmatic activities of the Yanshan episode. The spatial distribution of ore-bodies was jointly controlled by the NE strike F3 fault and the Shujing anticline developed in the hanging wall of F3. Based on the comprehensive study, the authors propose that the regular spatial occurrences of the ore-bodies in the mining district are closely related to the dextrorotation-oblique thrust motion of the NE faults.
