| 摘 要： | 文章综述了近年来桂西地区基础地质研究的重要进展。阐述了桂西晚古生代深水沉积的分布特征 ,简介了深水相地层序列并对桂西晚古生代的构造沉积背景作了新的解释。对长期以来认为是侵入岩的广泛分布于桂西晚古生代地层中之基性岩浆岩 ,认为应属火山岩 ;文章还对右江海盆晚生古代以来的地质发展史提出了与“右江再生地槽”理论完全不同的观点 ,并对桂西地区特殊的地质观象———“化石脉”的成因作了探讨

| Abstract: | This paper report the important new development on research of Late Palaeozoic from western Guangxi, include the distribution of deep-water sediment with its sequences and structure sedimentary background; Late Palaeozoic bassic lava which were considered as the diabase, recently recognized that were oceanic basalt intergroun with Late Palaeozoic tectonic environment and geological history in Guangxi, and also discussion for the special"fossils line"(sedimentary dike) from carbonate platform. |
