| 摘 要： | 根据野外地质特征,结合微量元素和稀土元素分析结果,探讨了黔西南高砷煤的成因。高砷煤的形成,受岩浆岩、岩性、岩相古地理以及地质构造等诸多控矿因素的制约。高砷煤的形成经历了矿源层形成、龙潭煤系形成、含矿热液形成以及沉积-改造成矿等4个阶段。

| Abstract: | Based on field geological properties and chemical analysis results,the metallogenetic factors and genesis of high-As coal in southwestern Guizhou Province are disscused in this paper.According to the analysis of ore-forming geological factors,the formation of the high As coal was restricted by various orecontrolling factors,such as the magmatic rock factors,the sedimentary facies and paleogeographic factors,the lithological factors,the structure factors,and so on.It can be considered that the enrichment of arsenic may be divided into four stages: stage of the ore source bed formation,stage of the Longtan coal-bearing rock series formation,stage of the ore-bearing hydrothermal formation,stage of the high arsenic coal deposit formation. |
