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。
The research progresses on some key issues in deep geological research in South China in recent years are analyzed. It is proposed that “Banxi Group” is not a tectonic melange formed during the Mesozoic collision orogeny, but a set of sedimentary caprocks with weak metamorphism and obvious bedding and continuous formation in the south of the Yangtze River. South China widespread widespread Archean crystalline basement. Ancient Paleozoic tectonic environment mainly for the continental margin stretching basin. According to the metamorphic phase, the crust in South China can be divided into three layers from top to bottom and evolved in two phases.
