Abstract:
This is an article in the field of earth sciences. The copper resources in Ningxia are relatively poor, and 15 copper producing areas have been basically identified, of which 6 deposits have been explored, and the accumulative amount of copper metal has been identified as 29210.71 tons. There are two types of copper deposits: epigenetic medium-low temperature hydrothermal deposit and placer deposit. The mineralization process is magmatism, sedimentation,ore-bearing fluid process (non-magmatic-non-metamorphic process). Copper deposits are mainly distributed in Weining Beishan area, Xiangshan area, South West Huashan area and the southern area of Liupan Mountain. The metallogenic ages are Caledonian, Varissian, Indosinian and Yanshanian, mainly Caledonian and Yanshanian. According to the study on the metallogenic geological law of the existing deposits, the magmatic hydrothermal type and continental sedimentary type are taken as the key prediction types. According to the material composition of the ore-forming series, five ore-forming series related to copper are determined, and the ore-forming genealogy of copper ore is summarized. The research on metallogenic regularity of copper ore is improved. It provides a theoretical basis for the potential evaluation and prediction of copper resources in Ningxia.
