| 摘 要： | 贵州省的镍钼钒多金属矿分为岩浆熔离型铜镍矿、热液型多金属矿床中的镍钼钒矿、沉积型镍钼钒矿和次生淋滤型镍钼矿等4种矿化类型。文章重点介绍了沉积型镍钼钒矿的成矿地质特征,分析了其成矿条件及找矿标志,探讨了黑色岩系底部镍钼钒多金属矿层的成因机理,提出了"白烟囱"型的成硅(磷)、成矿、生物爆发的形成机制和被动大陆边缘构造、岩相古地理、深部岩浆岩及断裂构造等控制因素。

| Abstract: | Ni-Mo-V poly-metal deposits in Guizhou province are divided into four types, i.e., magma liquation Cu-Ni deposit, hydrothermal Ni-Mo-V deposit and sedimentary Ni-Mo-V deposit and secondary leaching Ni-Mo deposit. This paper is stressed geological and metallogenic characteristics of the sedimentary Ni-Mo-V deposit. The metallogenic condition and prospecting marks are analyzed, genetic mechanism of Ni-Mo-V ore layer at bottom of black shale sequence explored and the ore control factors, such as mechanism of "white chimney" type Si-P layer and organism explosion, passive continental margin, lithofacies palaeogeography, deep magmatite and fault, etc. put forward. |
