| 摘 要： | 华南是我国地质研究的立典地之一。近年又有若干新发现,获得大批新数据,产生了许多新认识。本文初步总结了华南前侏罗纪地质研究中取得的新进展、新成果以及出现的新问题,结合自己的工作,进行了综合评述,兼谈了自己的认识。主要内容包括前寒武纪地质特征(多地体的构造格架、碰撞拼合带位置的厘定、华夏古陆问题、新元古代变质作用)、华南原始大陆形成的时间与证据、华南早古生代褶皱带构造属性(陆内造山前构造、早古生代地层序列与沉积环境、陆内造山的证据、陆内构造-岩浆作用特征、早古生代陆内造山的驱动力)、晚古生代沉积环境与早中生代构造-岩浆作用的构造背景(晚古生代含放射虫硅质岩问题、晚古生代地层序列、早-中三叠世花岗质岩浆活动特征、早中生代构造-岩浆活动的动力学机制)以及华南地质研究中值得注意的一些问题等。期盼借此引起业内同行的重视,促进华南地质研究的前进步伐。

| Abstract: | South China is one of the best developed areas for geological research in China. Recent discoveries based on new data have significantly improved the understanding of the pre- Jurassic tectonic evolution of South China. This paper combines our new results with the previously available literature to highlight new scientific challenges. The major advances on the South China geology include (1) the Precambrian geological features such as the tectonic framework of multiple terranes, the location of collision/suturing zone between the Yangtze and Cathaysia blocks, the nature of so called Cathaysia Oldland and Neoproterozoic metamorphism, (2) the formation time and evidence for Proto- South China Continent, (3) the tectonic significance of the Early Paleozoic folded belt in the South China, including pre- tectonic settings of intracontinental orogeny, the stratigraphic sequences and depositional environments in the Cambrian- Ordovician period, the evidence and indications of intracontinental orogeny, the genesis of widespread S- type granitic magma and the driving mechanism of the intracontinental orogeny, (4) the Late Paleozoic depositional environment and the Early Mesozoic tectonism and granitic magmatism, such as the stratigraphic sequences and the depositional environment of the radiolarian- bearing cherts, the nature and origin of Early- Middle Triassic S- type granitoids, and the geodynamics of the Early Mesozoic tectonic and magmatic event. This paper also discusses several critical challenges in the geological studies of the South China. With this article, we look forward to drawing the attention of the geological society and promoting the study of the South China geology. |
