| 中文摘要: |
| 黔东南地区石英脉型金矿找矿勘查难获突破，甚至关于成矿作用过程的研究也有待深入，本文根据《中国区域地质矿产志·贵州卷·金矿》编撰过程中所掌握的各类资料文献，结合近些年关于金的成矿作用思考和地质观察，尤其是天柱金井金矿“纯净”石英脉明金似层状成矿、黎平三什江金矿(含金)石英脉白云石“层状”条带构造特征现象，以及天柱扒草金矿顺层(含金)石英脉稀土元素及微量元素对称性分布的地球化学分析等表明，黔东南地区石英脉型金矿并非传统认识的沉淀沉积成矿，而应为载体石英脉挂壁结晶生长、自然金粘附成矿的结果，其过程首先进行的是含矿热液混浊期成矿，形成主要产于暗色杂质条带的细粒明金成矿及其富矿金包和“狗头金”等，然后才是含矿热液干净期成矿，形成比较厚大的纯净石英脉及其中似层状明金成矿。 |
| 英文摘要: |
| In southeast Guizhou, it’s hard to make breakthrough in quartz vein gold exploration, even the research of mineralization process need to go further. In this paper, on the basis of known different information during the writing of ‘China Regional Geological mineral chronicles (Guizhou, Gold)’, with the consideration of gold mineralization and geological observation in recent years, mainly is ‘pure’ quartz vein visible gold stratiform-like mineralization of Jinjing gold deposit in Tianzhu, (gold bearing) quartz vein dolomite banded structure distribution phenomena of Sanshijiang gold deposit in Liping, especially the symmetry distribution and geochemical analyses of (gold bearing) bedding quartz vein rare earth element and trace elements of Bacao gold deposit in Tianzhu, all these shows that the quartz vein gold deposit in southeast Guizhou is not traditional precipitation and sedimentary mineralization, it should be the results of carrier quartz hang crystal growth, natural gold adhesion. In the progress, firstly is ore bearing hydrothermal turbidity period mineralization, formed fine grain visible gold mineralization occur in dark impurity belt and its rich gold pack, gold nugget, then is ore bearing hydrothermal mineralization in the pure period, formed bigger pure quartz vein and stratiform-like visible gold mineralization. |
