湘西—鄂西成矿带自新太古界至第四系均有发育。依据大地构造演化特征，结合地层发育特征及岩相古地理，按青白口纪和南华纪—震旦纪两个阶段进行地层区划分。青白口纪时期，研究区分为南秦岭地层区、黄陵地层区、梵净山地层区、武陵-雪峰地层区与四川盆地区。南华纪-震旦纪时期，研究区分为南秦岭地层区武当地层分区、陨均台地层分区及扬子地层区湘黔鄂地层分区、湘中分区。对成矿带岩石地层提出了对比方案，主要为：石桥铺组和黄狮洞组来替代甲路组；沿用乌叶组而弃用砖墙湾组；重新定义清水江组，将以板岩为主的地层都归属清水江组，相当于番召组上段、清水江组、平略组之和；保留原清水江组之上的隆里组而弃用平略组（黔）和岩门寨组（湘）；弃用陨均台地区的“陡山沱组”和“灯影组”，沿用尚家店组和青山寨组的定名；采用老堡组来替代留茶坡组。

The stratigraphy of Western Hunan-Hubei metallogenic belt has developed since the Neoarchean to Quaternary period. According to the characteristics of geotectonic evolution, stratigraphy and lithofacies palaeo-geography, we divide the Neoproterozoic stata of the area into the Qingbaikou stage and Nanhua-Sinian stage. During the Qingbaikou stage, the metallogenic belt is divided into five stratigraphic regions called Southern Qin-ling, Huangling, Fanjingshan, Wuling-Xuefeng and Sichuan basin, respectively. During the Nanhua-Sinian stage, the belt is divided into Southern Qinling stratigraphic region (including Wudang and Yunjuntai stratigraphic sub-region) and Yangtze stragraphic region (including Hunan-Guizhou-Hubei and Central Hunan stratigraphic subre-gion). We also recommende to adopt or redifine some stratigraphic units. Keep Huangshidong Formation and Shiqiaopu Formation instead of Jialu Formation, use Wuye Formation and discard Zhuanqiangwan Formation. Qingshuijiang Formation is redefined to describe the main slate strata and equivalent of the combination of the up-per part of Fanzhao Formation, Qingshuijiang Formation, Pinglue Formation. Disuse Pinglue Formation (Guizhou)and Yanmenzhai Formation (Hunan) and keep Longli Formation. The “Doushantuo Formation”and“Dengying Formation”in the Yunxian and Yunxi area are replaced by “Shangjiadian Formation”and “Qingwangzhai For-mation”, respectively. Disuse“Liuchapo Formation”and persist“Laobao Formation”.
