通过对煎茶岭硫化镍矿床地质背景及矿石的地质地球化学研究,认为该镍矿床的形成与煎茶岭镁质超基性岩体密切相关,其成矿物质来源于深部,存在多种成矿作用,包括源自上地幔局部熔融的母岩浆在通过上地幔岩石圈上升侵位过程中发生的就地熔离作用和岩体形成后的自变质作用、中酸性岩浆侵入引起的热液叠加改造作用等。后期中酸性岩浆热液的交代改造是形成该矿床中部分富镍矿体的主要原因。该镍矿床PGE含量较低且贫铜,成因上应属岩浆熔离-热液改造型矿床。
Based on the geological background and geological geochemistry of the Jianchaling sulfide nickel deposit, it is considered that the formation of this nickel deposit is closely related to the Jianchaling magnesian ultramafic rock. The metallogenic materials come from the deep and there are many mineralization , Including the local metasomatism that occurred during the upwelling of upper mantle lithosphere and the self-metamorphism after the formation of mantle magma originating from local melting of the upper mantle and the hydrothermal superposition and remodeling caused by the intrusion of magmatic magma Wait. Late replacement of intermediate-acidic magmatic hydrothermal fluids is the main reason for the formation of some nickel-rich orebodies in this deposit. The low PGE content and low copper content of the nickel deposit should be attributable to the magmatic eruptive-hydrothermal alteration deposit.
