摘　　要：二叠系龙潭组是黔西南重要成煤期煤系地层,更是许多微细粒浸染型金矿的赋矿地层之一,该套地层底部金及相关低温元素(As、Ag、Sb、Hg、Tl、Pb和Zn)丰度较高,为一煤金建造,该建造具有丰富的物源、热源和水源和良好的层位、岩性组合及构造条件,这些对金矿形成贡献作用明显,认为龙潭组煤金建造在黔西南一些金矿形成过程中的控制作用至关重要。In SW Guizhou province, the Longtan Formation is an important the coal system stratum one of formations for micro-disseminated gold ores. The bottom of the strata contains plenty of Au and low temperature elements which is related to the formation of gold deposit, such as As, Ag, Sb, Hg, T1, Pb and Zn. Therefore, the bottom of the strata belongs to coal-gold construction, which possesses plenty of material sources, heat sources and water sources, and at the same time it has good layers, lithologie and structural conditions. All of above obviously contributes the formation of gold. We primarily think that Longtan coal-gold construction is very important to the formation of some gold deposit in the southwest of Guizhou Province.
