    宁夏铜矿成矿地质特征与成矿规律

    Geological Characteristics and Metallogenic Regularity of Copper Deposits in Ningxia

    • 摘要: 这是一篇地球科学领域的论文。宁夏铜矿资源相对贫乏,现已基本查明铜矿产地15处,其中做过勘查工作的矿床有6个,累计查明铜金属量29 210.71 t。铜矿床类型有浅成中-低温热液型矿床和砂矿型矿床两类,成矿作用为岩浆作用、沉积作用、含矿流体作用(非岩浆-非变质作用)。铜矿产地主要分布于卫宁北山地区、香山地区、南西华山地区及六盘山南部地区,成矿时代为加里东期、华力西期、印支期、燕山期,其中以加里东期和燕山期为主。根据对现有矿床(点)的成矿地质规律的研究,将岩浆热液型和陆相沉积型作为重点预测类型。依据矿床成矿系列的物质组成,厘定出5个与铜相关的矿床成矿系列,总结了铜矿成矿谱系,提升了铜矿成矿规律研究的程度,为宁夏铜矿资源的潜力评价预测工作提供了理论依据。

       

      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.
