| 摘 要： | 根据湖南地层发育情况，依国际地层划分标准和中国地层指南要求，将湖南省境内原震旦纪早世划归新元古代南华纪，地层系统可分为3个相区。综合已有同位素测年数据，初步建立起南华纪年代构造格架，确立南华纪底界年龄为800Ma左右，顶界年龄为700Ma左右．

| Abstract: | Former Lower Epoch Sinian Period was put under Nanhua Period, and the stratum system divided into 3 correlative areas according to the Hunan stratum development situation and the demand of international stratigraphy division standard and China stratigraphy guide. By the known data of isotope age determination, Nanhuaian time-structure frame was principally set up with the top boundary about 700 Ma and bottom about 800 Ma. |
