| 摘 要： | “深部熔离-贯入式”岩浆铜镍硫化物矿床具有矿化比例极高、岩体岩相分带及矿体产状与原地分异、熔离机制不协调的特征.我国对这类矿床深部勘探策略和方法的研究相对滞后,尚未开展深部找矿工作.本文以金川矿床为重点,系统总结和归纳其地质特征和成矿有利部位,对比了与之成因类似的加拿大Voisey＇s Bay超大型岩浆Gu-Ni-Co硫化物矿床的成功勘探经验,阐述了这类矿床沿岩浆通道找矿的前景和巨大潜力.以金川矿床为实例,提出了这类矿床沿含矿岩浆通道开展深部找矿的策略和方法. |
| 关 键 词： | 岩浆型铜镍硫化物矿床 岩浆通道找矿 金川矿床 |

| Abstract: | Magmatic Ni-Cu sulfide deposits formed by "injecting of sulfide-bearing magmas segregated at depth"are hosted in intrusions with high proportions of sulfide ores. The lithologic variations and distribution of sulfide orebodies in the intrusions are inconsistent with model of in-situ magmatic fractionation and sulfide segregation. Many such deposits had been identified in China. However, corresponding method for further exploration of the ore bodies in depth in these deposits has not been developed well. In this paper, we summarized marked geological features of this type of deposits in China, including the Jinchuan deposit. Exploration of the Voisey's Bay super-large Cu-Co-Ni sulfide deposit in Canada, which is genetically similar to the Jinchuan deposit, was described. We proposed that it is potential to prospect new ore-bodies along sulfide-bearing magma conduit at depth. We also presented method prospecting new ore bodies along the conduit of sulfide-bearing magmas in the Jinchuan deposit. |
