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。This paper deals with the advance of researches in depth geology of South China. Sev- eral important conclusions have been derived , including: ① The Banxi Complex was not formed by collision in Mesozoic. lt 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. ④.The crust may be divided into three layers based on metamorphic fancies ,and it developed through two stages.
