| 摘 要： | 分析了近年来华南地区深部地质研究中若干焦点问题的研究进展。提出“板溪群”不是中生代碰撞造山过程中形成的构造混杂岩,而是分布于江南古陆的一套变质变形微弱、层理明显、岩层连续有序的沉积盖层。华南地区广泛存在太古代一元古代的结晶基底。元古宙的古构造环境主要为大陆边缘拉张盆地。根据变质相华南地区地壳自上而下可划分为三层,分两个阶段演化。

| Abstract: | This paper deals with the advance of researches in depth geology of South China. Several important conclusions have been derived,including:①The Banxi Complex was not formed by collision in Mesozoic. It is a Weakly metamorphosed sedimentary strata.② The Pt1-Ar crystallized basement was widely scattered over South China.③The Proterozoic tectonic environment was formed in extension basins near continental margin .The crust may be divided into three layers based on metamorphic facies,and it developed through two stages. |

| Keywords: | metamorphic basement Crust composition South China |
