A Research on Geological Characteristics and Exploration Direction of Cuijiagou Lead Zinc Mine in Ruzhou City,Henan Province
The Cuijiagou Lead-Zinc Mine in Ruzhou City,Henan Province,is situated within the Ruyang-Jiliaoxiang depression belt of the North China landmass,specifically within the Cambrian carbonate formation of the Sino-Korean paraplatform,representing a long-term sedimentary area under stable conditions.The mine's strata primarily consist of the Neoproterozoic Luoyukou Group and Cambrian formations such as the Xinji,Zhushadong,and Mantou formations.The fracture system is well-developed,while folding is minimal.The ore body,hosted within the Cambrian Zhushadong Formation,exhibits distinct stratigraphic control.Mineralization is not associated with magmatic activity,and intrusive rocks are sparse within and surrounding the mining area.The enrichment of the ore body and associated mineralization is closely related to fault structures.The ore body occurs in forms such as veins,layers,and lenses.The country rocks of the mineralization are the lower Cambrian banded dolomite and leopard skin limestone.The main alterations in the country rocks near the ore body include silicification,carbonatation,and baritization.These represent low-temperature hydrothermally altered,layer-controlled lead-zinc deposits.
