摘要: 纵观近年来中国南方中新元古代古大陆研究的现状与进展，取得的成果主要体现在以下两个方面：（1）与华南古大陆演化有关的新元古代裂谷作用研究、冰川沉积事件研究、板溪群地层划分对比等取得了一系列重要成果；（2）与古大陆演化有关的火山—岩浆事件及其岩石地球化学研究、同位素地球化学研究及年代学研究等获得了一系列新的数据与新的认识。针对目前华南古大陆研究中存在的主要问题，特别是晋
宁—四堡不整合面之上“楔状地层”的划分对比问题、沉积演化及其大地构造背景问题，不整合面之下变质岩系的时代归属及沉积盆地性质问题等，作者开展了较详细的讨论，试图引起国内外同行的重视，以期达到抛砖引玉之目的。-

Abstract: Numerous studies have been conducted in recent years on the Neoproterozoic South China palaeocontinents, and notable advances are generalized in the following aspects, including: (1) advances in the researches of the Neoproterozoic Nanhua rifting related to the evolution of the South China palaeocontinents, Chang’anian and Nantuoan glaciation and sedimentary events, and stratigraphic division and correlation of the Banxi Group, and (2) progress towards the researches of volcanicmagmatic events associated with the palaeocontinental evolution and concomitant studies of lithogeochemistry, isotope geochemistry and chronology. In view of the current status of research, the authors in this paper present a detailed review of the researches of Neoproterozoic South China palaeocontinents, especially the stratigraphic division and correlation of the wedgeshaped strata above the JinningSibao unconformity and the ages of the metamorphic rocks beneath the unconformity, the attributes of sedimentary basins, sedimentary evolution and tectonic settings. The authors have also been looking forward to greater progress in the studies of the abovementioned fields in the near future.-
