Abstract:
The Western Liaoning Region is located in the middle section of the northern margin of North China, at the intersection of two major tectonic mineralization domains, the ancient Asian Ocean and the Pacific Ocean, and is one of the important gold rich areas in China. Based on regional geological background investigation, typical deposit dissection, and exploration results analysis, this paper systematically studies the temporal and spatial distribution law of the of gold mineralization belts in Western Liaoning Region, reveals the coupling control mechanism of structure magma stratigraphy, and quantitatively predicts the potential of deep resources. Research has shown that the spatial distribution of gold mineralization belts in Western Liaoning is in a “diamond pattern”, which is jointly controlled by latitudinal uplift zones, deep faults, and northeast (NE) tectonic magmatic zones; focusing on the two major mineralization stages of the Archean basement formation period and the Yanshanian tectonic magmatic activity period in terms of time. The deep resource potential is enormous, with key target areas including the deep porphyry type ore body in the Baizhangzi Mining Area, the deep extension zone of the Paishanlou Gold Deposit, and the erosion skylight area of the Chifeng-Chaoyang Ore Belt. It is predicted that the potential for new gold metal reserves will exceed 2 000 tons. The research results provide theoretical support and practical guidance for deep mineral exploration in the Western Liaoning Region.
