| 中文摘要: |
| 万丈沟镍钴矿床为柞水—山阳矿集区内目前唯一一个与基性—超基性岩密切相关的小型镍钴矿床。该矿床位于区域性山阳—凤镇大断裂北侧，已圈定了 8条镍钴矿体，矿体赋存于泥盆系细碎屑岩-碳酸盐岩地层中的断裂构造带中。本文通过对万丈沟镍矿的地质特征、矿体特征及矿石质量特征研究，分析了该矿床的控矿因素，总结了找矿标志；通过对已有的矿床地球化学资料进行分析研究，认为万丈沟镍钴矿化成因上为与基性—超基性岩浆有关的碳酸角砾岩型矿化。在上述研究的基础上，总结了该矿床的成矿模式，认为万丈沟镍钴矿床浅部为受构造控制的与岩浆活动有关的岩浆热液型矿床，深部仍具有寻找与基性—超基性岩有关的岩浆熔离型铜镍钴硫化物矿床的潜力。 |
| 英文摘要: |
| Wanzhanggou Ni-Co deposit is the only small-scale Ni-Co deposit, which is closely related to thebasite-ultramafic rocks in the Zhashui-Shanyang ore concentration area. The deposit is located on the north side ofthe regional Shanyang-Fengzhen fault, and 8 nickel-cobalt ore bodies have been delineated, which are located inthe fault structure zone of the Devonian fine clastic-carbonate rock strata.By studies the geological characteristics,ore body characteristics and ore quality characteristics of Wanzhanggou nickel cobalt deposit, this paper analyzesthe ore control factors of the deposit, and summarizes the prospecting markers; By analyzing the previous geochemi-cal data of this deposit, it is concluded that the nickel and cobalt mineralization in Wanzhanggou is of carbonatebreccia type related to basite-ultramafic magma. Based on the above studies, summarized the mineralization modeof the deposit. It is concluded that the shallow of Wanzhanggou nickel-cobalt deposit is a magmatic hydrothermaldeposit controlled by tectonics and related to magmatic activity, while the deep still has the potential to find a mag-matic Cu-Ni-Co sulfide deposit. |
