【摘要】 自从在东北南部发现早石炭沉积之后，笔者研究了该区下石炭统的分布、层型、沉积类型、岩相古地理、古生物及其地理分区等的特征，认为该区早石炭世沉积属地台型建造，由海陆交互相的陆源碎屑岩组成，形成了滨海—滨海沼泽环境，其沉积中心形成于氧化潮坪—泻湖环境。区内古生物组合明显具有欧美植物群和早期华夏植物群的色彩，与区域对比，可以独立划分古生物地理区。在此基础上，本文建立了一种新的早石炭世沉积类型——东北型和一个新的早石炭世古生物地理省——华北省，从而为中国早石炭世沉积特征、古生物及其地理分区以及岩相古地理等方面的研究提供了一些新资料和新的认识。更多还原

【Abstract】 ince the Lower Carboniferous discovered in Northeast China, the author has studied the characteristics of its distribution, stratatype, sedimentary types, lithofacies paleogeography, paleobiography and its geographic provinces etc. It is concluded that the Lower Carboniferous sedimentary is of platform type, which is consisted of terrigenous clastic rocks from the transition between marine and continental facies, its depositional environment is littorallittoral swamp facies, and its depositional center is in oxidized tidal flat facies. The transgressive direction is from south to north or northeast. The flora has some common features with Euramerian and Early Cathaysian flora. Then, a new type of sedimentary type is named Northeasttype and a new paleobiogeographic province is named North China province. So the paper can supply some new data and new knowledge to further studies on the Lower Carboniferous of China.更多还原
