| 摘 要： | 黔西南地区上二叠统和中下三迭统是一个重要的多元素含矿建造,其中某些层位中的 Au、As、sb 和 Hg 的含量均高于上部陆壳克拉克值。该区微细粒浸染型金矿床集中分布于上二叠统和中、下三叠统地层中;金矿石在微量元素,稀土元素和稳定同位素组成特征上与围岩表现出较好的一致性,反映了金矿的成矿物质主要来自地层。

| Abstract: | Most of the micro-fine-disseminated gold deposits in SouthwesternGuizhou province are located in the Upper Permian and Middle-Lower Triassic systems which aer the most important ore-bearing formations of poly-elements and have the high contents of Au,As,Sb and Hg.Their compositions of trace elements,REE and stable isotope are very silmillar to those of their wall rocks.The ore-bearing formations are the source beds for gold and play a very important role in the formation of the gold deposits in this area. |
