| 摘 要： | 文章从矿物学、矿床地球化学等方面对贵州省下寒武统黑色岩系型多金属矿床的研究进展进行综合评述,研究表明：贵金属主要以硫化物形式均匀散布于黄铁矿等硫化物中,超常富集的PGE、Au可能主要以不可见有机结合态、无机结合态和吸附态等赋存于矿石干酪根中;碳硫钼矿是Mo的主要存在形式,钒则主要以类质同像形式存在于粘土矿物水云母中;镍钼层矿石成矿年龄521±54Ma-542±11Ma,与赋矿地层成岩年龄531±24 Ma基本一致;硫主要来源于生物对海水硫酸盐的还原,高度富集的多金属元素层主要为海底热水沉积作用形成;矿床成矿流体主要是盐度较高的海底含矿热卤水与正常海水混合沉积的产物;南华纪-早古生代阶段,湘黔地区南华裂谷海槽洋壳向华夏古陆俯冲及扬子陆块向南华裂谷海槽洋壳俯冲的构造环境及其诱发的挤压-伸展构造机制的多次转换等事件为矿床形成提供了有利的成矿通道与就位场所。

| Abstract: | Comprehensive review was carried out on research advancement of polymetallic deposit in Lower Cambrian black rock series of Guizhou Province from the view of both mineralogy and geochemistry of ore deposit.The research on mineralogy shows that most of the precious metals are evenly distributed in sulfides(such as pyrite),and extremely enriched PGE and Au may mainly occur in the kerogen of ores in the form of invisible organic bond,inorganic bond and absorbed state;C-S-Mo ore is the main occurrence form of M... |
