1 Overview and Regional Geological Background The Gongshangzi copper-zinc-tungsten deposit is located in Binxian County, Bin Dong area. Its tectonic location is located in the margin of the Xiaoxing’anling-Zhangguangcailing tectonic magmatic belt on the margin of the Late Triassic Binhai Pacific, the western margin of the Zhangguangcailing Uplift, The continental margin basin and the central Bin Dong uplift belonged to the Zhangguang-Caraling metallogenic belt. Outcrops of the deposit and its peripheral areas are mainly exposed from the Devonian to the Quaternary. Among them, the Middle Permian Tumenling Formation is the main near-ore rock in the area, especially the Middle Permian Tumenling Formation marble, which is closely related to the mineralization. mine
