自８０年代以来，华南大地构造格局问题的讨论是我国地学的热点之一。有关华南陆块地质构造演化及形成时代存在多家之说，其中“江南古陆”是否存在与原“板溪群”时代的归属是争论的焦点。许多学者从不同的角度提出了各种观点和构造演化模式。从近几年来在皖南、赣东北地区的一系列新发现，可以得出如下看法：（１）“板溪群”不是一个前震旦纪的变质地层单位；（２）“江南古陆”是不存在的；（３）华南不存在加里东后地台，而存在晚古生代洋盆，它可能是东特提斯洋的一部分；（４）印支运动在赣东北地区有重要的表现，晚古生代浅变质岩和蛇绿混杂岩是它的岩石记录 Since the 1980s, the discussion on the tectonic setup of the South China is one of the hot spots in geosciences in China. The geological evolution of the South China Block tectonic evolution and the formation of a number of times that the existence of the “Southern Yangtze River” and the original “Banxi Group” era belongs to the debate is the focus. Many scholars put forward various views and tectonic evolution models from different perspectives. From a series of new discoveries in southern Anhui and northeastern Jiangxi in recent years, we can draw the following opinions: (1) “Banxi Group” is not a metamorphic stratigraphic unit of the Pre-Sinian; (2) “Old Southern Yangtze” is not (3) the Late Caledonian platform was absent in South China, whereas the Late Paleozoic ocean basin existed, which may be a part of the Eastern Tethyan Ocean. (4) The Indo-Chinese Movement has an important manifestation in northeastern Jiangxi Province. Late Paleozoic Shallow metamorphic rocks and ophiolite melanges are its rock records
