| 中文摘要: |
| 研究主要针对黔西南地区构造蚀变体(SBT)中大厂锑矿床的典型剖面,采集茅口组的茅口灰岩,龙潭组的碳质泥岩、粉砂岩、粘土岩,峨眉山玄武岩组凝灰岩、沉凝灰岩、碳质粘土岩和SBT中的强硅化灰岩、角砾状强硅化灰岩、硅质岩、凝灰岩及角砾状粘土岩组合,对岩石或矿石进行主量元素和微量元素分析,利用等离子质譜方法分析大厂地区构造蚀变体及其上覆地层和下伏地层各类岩石样品的稀土元素组成。表明热液蚀变作用强烈,成矿物质可能为深部成矿流体带入。 |
| 英文摘要: |
| This study mainly focused on the typical section of the DaChang antimony deposit in the structural alteration terrane (SBT) in southwestern Guizhou, and analyzed the main elements and trace elements of rocks or ores.The samples in the analysis were from Maokou limestone in the Maokou Formation, carbonaceous mudstone, siltstone, and claystone in the Longtan Formation, tuff ,sedimentary tuff, carbonaceous clay rock in the Emeishan basalt Formation,and strong silicified limestone,brecciform strong silicified limestone, silicalite, tuff, and brecciform claystone combinations in the SBT. The analysis method is to use plasma mass spectrometry to analyze the rare earth element composition in various rock samples of SBT and its overlying and underlying layers in DaChang region.The results show that the hydrothermal alteration is strong and the metallogenetic material may be brought in by deep metallogenic fluid. |
