中国南方泥盆纪地层分布广泛,长期以来就以地层发育完整、化石丰美而著称于世。总的来说,华南泥盆纪沉积,可以根据大地构造单元、地层发育特征和生物群面貌,进一步划分为东、西两区:西区包括西藏、滇西、川西、西秦岭和昆仑山南坡一带,主要是冒地槽类型的海相沉积,与下伏志留系呈整合接触,产大量的底栖生物和浮游生物。东区包括龙门山地槽和康滇古陆以东的广大地区,基本上属于地台型沉积,产丰富多种的各门类化
The Devonian strata in southern China are widely distributed and have long been known for their complete stratum development and fossil abundance. In summary, the Devonian sediments in South China can be further divided into eastern and western regions according to tectonic units, stratigraphic development features and biome appearances: the western region includes Tibet, western Yunnan, western Sichuan, western Qinling and the southern slopes of the Kunlun Mountains Mainly marine trough-type marine sediments that are in integrated contact with the underlying Silurian system to produce large amounts of benthic organisms and plankton. The eastern region includes the Longmenshan Gully and the vast areas east of the Kang-Dian Old Land. Basically, it belongs to a platform-type sediment, with a wide variety of categories
