赣西南地区前寒武纪地层发育，出露面积广，属东南地层区桂湘赣地层分区。因地层分区内不同地段的地层发育程度及沉积特征常有差异，可进一步划分出若干地层小区，并介绍了地层小区的岩石地层单位特征、划分及对比，分析了该区不同时期的古沉积环境及岩相变化规律。

The stratum of precambrian in Jiangxi southwest area develops and appears in a large area, which belongs tothe stratum sector of Gui, Xiang, Gan in Eastsouthern stratum area. Owing to different developing degrees and depositingfeatures resulting from different section within the stratum sector, this paper decentralizes the area into divers stratumarea as well as introduces the charactevistics, the division and contrast of rock stratum unit in stratum area. Finally thepaper analyzes paleodeposit circumstance and variety regularity of rock facies of different eras in the area.
