| 中文摘要:通过对金川铜镍硫化物矿床中58号矿体地质特征、亲铜和亲铁元素地球化学特征等方面的研究,发现其具有不同于24号矿体、1号矿体和2号矿体的地质和地球化学特征。58号矿体产于Ⅲ号岩体上盘围岩中,矿体总体走向为NNE,倾向NW。与金川矿床其他几个矿体比较,该矿体具较高的Cu、Ni和PGE含量。研究独立的58号矿体对全面理解整个金川超基性岩体的成矿规律,指导今后找矿工作具有重要意义。笔者认为58号矿体的硫化物是从PGE微弱亏损的苦橄质岩浆中熔离出来的,其硫化物熔体具有不同的分异演化过程。 |

| Abstract:The study of No. 58 ore body is not only very important for understanding the formation and distribution of the Cu-Ni sulfide ore bodies at Jinchuan but also significant for further exploration. Studies indicate that the geology and siderophile and chalcophile element geochemistry of No. 58 ore body are different from those of No. 24, No. 1 and No. 2 ore bodies. The NNE-striking elongate No. 58 ore body was emplaced in the hanging wall of Segment Ⅲ and dips northwestward. Compared with other major ore bodies of the Jinchuan deposit, No. 58 ore body has higher Cu, Ni and PGE content and its sulfide was produced by secondary sulfide segregation picritic magma slightly depleted in PGE, with the sulfide experiencing fractional crystallization in various degrees. |
