湘东赣西晚泥盆世地层划分,其中包括翻下段铁矿层位对比,长期以来看法不一。1936年,高平、徐克勤在江西萍乡铁矿调查时,把中、上泥盆统称狮背系,上统为上株岭层,中统为石灰冲层和山口崖层。1942年,田奇(王崔乃)、刘国昌在湖南茶陵、攸县、醴陵一带找到Yunnanella和Yunnanella,认为湘东存在晚泥盆世锡矿山期沉积。1954年,廖士范等根据湘赣边境铁矿勘探资料建立佘田桥系,由下至上分为麻石岭段、煤炭冲段(后改为活
The late Devonian stratigraphic division in the western Jiangxi Province, including the contrast of the inverted iron beds, has long been mixed. In 1936, Gao Ping and Xu Keqin investigated the middle and upper Devonian Lions back in the investigation of Pingxiang Iron Mine in Jiangxi Province, which was collectively referred to as Upper Zhuling Ridge and Middle Limestone Ledge and Yamaguchi Cliff. In 1942, Tian Qi (Wang Cui Naai) and Liu Guochang found Yunnanella and Yunnanella in Chaling, Youxian, and Liling areas in Hunan Province, and found that there was the Late Devonian tin deposit in the eastern Hunan. In 1954, Liao Shi-fan and others established the Shetian Bridge system according to the iron ore exploration data in the border areas of Hunan, Gansu and Jiangxi Provinces. From bottom to top, they were divided into Ma Shiling section, coal section (later changed to live
