湖南泥盆系发育良好,化石丰富,是研究我国南方泥盆系的重要地区之一。以往对浅海相地层如中统棋梓桥组、上统佘田桥组和锡矿山组研究较详,而对陆相—滨海相地层如跳马涧组工作不够。长期以来无论湘中或湘南都习惯把中统棋梓桥组以下一套碎屑岩统称为跳马涧组,并认为属中泥盆世沉积,近年与外省对比还将其全部置于中泥盆统吉维特阶(D~2_2)下部。虽少数同志怀疑湘南跳马涧组下部可能属早泥盆世,但均无化石依据,故
Devonian in Hunan is well-developed and rich in fossils, which is one of the most important areas for studying the Devonian in Southern China. In the past, research on shallow marine strata such as Zizhongzi Zixiaqiao Formation, Shetianqiao Formation and Xikuangshan Formation was more detailed, while work on the continental facies-coastal phase strata such as the Jiaomajian Formation was not enough. For a long time, no matter whether Xiangzhong or Southern Hunan are accustomed to the following set of clastic rocks of the Zixi Qizhi Formation of the Central Uygur Autonomous Region collectively referred to as the “Komama Stream Formation” and believed to belong to the Middle Devonian sedimentation. In recent years, The lower part of the system of the austerity order (D ~ 2_2). Although a few comrades suspect that the lower part of the Xiemajian Formation in southern Hunan may belong to the Early Devonian, no fossil basis exists
