摘要
云南早石炭世生物地理区,根据生物组合,以北澜沧江断裂南接怒江断裂和柯街-南汀河断裂为界,从东向西分为特提斯华南生物地理分区、保山生物地理分区和冈瓦纳腾冲生物地理分区。
According to the biological complex, the biogeographic region in Yunnan from east to west, taking the northern Lancangjiang Fracture southwards connected with the Nujiang, Kejie-Nandinghe fractures as the boundary, can be divided into the biogeographic subregions of the south China, Baoshan of Tethys and Tengchong of Gondwana. The biota appearance of the Lower Carboniferous in Yunnan, South china subregions is similar to that in southeastern Guizhou and western Guangxi sub-regions. Besides the specific members in south China subregion, the Baoshan subregion often contains the coral fossils of Lithostrotion, Syringopora which only distribute in the Tethys subregion, therefore, the Baoshan massif should be classified with an area within Tethys subregion based on the biological complex features. The Tengchong subregion which mikes a feature of contai-ning the typical representative member Sinkiangopora only occurred in the north and Gondwana subregions is part of the Gondwana biogeographic subregion.
