| 摘 要： | 广西西部的基本地质面貌是广泛分布的三叠纪沉积中多处出露孤立的晚古生代地层。这些晚古生代地层往往伴随有大面积的基性岩。60年代和70年代的20万分之一的区测报告将它们划为中生代的基性侵入岩。

| Abstract: | The Hercynian "diabase", widely distributed in the western Guangxi, is now shown to be basalt associated with deep-sea siliceous and tuffaceous sequences. The deep-sea area should be considered a branch of the Paleo-Tethys, It was filled with detritus during the Triassic time due to the amalgamation of adjecent continental blocks and fragments, such as the Yang ze and Indosinian Blocks. |
