| 摘 要： | 本文通过对三塘湖盆地基底地层,特别是其中的火山岩的研究,对三塘湖盆地基底岩石组合及其形成的构造环境进行了分析,认为盆地基底主要由岛弧系列的火山岩及火山碎屑岩、碎屑沉积岩组成,早石炭世盆地所处位置为岛弧环境.通过岩石取样分析及与其它地区的对比,认为盆地局部铀源条件较好.

| Abstract: | Based on the study of basement rocks,especially the volcanics in the basement,the lithologic combination of basement rocks of Santanghu basin and the tectonic environment where these basement rocks were formed are analysed in this paper.It is suggested that the basement of the basin is composed of volcanics and pyroclastics of island-arc series and sedimentary clastic rocks,thus the basin was in island-arc environment in Early Carboniferous time.By analyzing the uranium content in basement rocks and comparing these data with those of other regions it is considered that the local uranium source in the basin area is favourable. |
