| 摘 要： | 河南省华北型石炭—二叠纪岩石地层可分为本溪组、太原组、山西组、石盒子组和孙家沟组，石盒子组又可分为小风口段、云盖山段和平顶山段。年代地层可分为１２个阶，生物地层可分为１０个连续组合带。岩石、生物及年代地层的对比表明，本溪组、太原组向南穿时，反映海侵由北向南；山西组上部和石盒子组向北穿时，揭示海水由南向北回泛。早二叠世前海水向南流注入北秦岭海槽，晚二叠世北秦岭褶皱，导致北秦岭海槽闭合，华北陆块南缘抬升、水体北流，成为内陆盆地。

| Abstract: | The North China type Permo-Carboniferous lithostratigraphy in Henan Province can be divided into Benxi,Taiyuan,Shanxi,Shihezi and Sunjiagou Formations in ascending order,and Shihezi Formation may be subdivided into Xiaofengkou,Yungaishan and Pingdingshan Members.The chronostratigraphy can be divided into 12 stages,and 10 continuous biostratigraphic assemblage zones can be established.The correlations of litho-,bio- and chronostratigraphic units indicate that the Benxi and Taiyuan Formations are diachronous southwards that reflecting the marine transgression from the north to the south.The upper part of Shanxi Formation and Shihezi Formation are diachronous northwards that revealing the flowage back from the south to the north.Prior to the Early Permian the marine water flowed southwards and injected into the North Qinling Trough.During the Late Permian North Qinling folded,leading to the closing of the North Qinling Trough and the uplifting of the south margin of the North China landmass,the water flowed northwards,and becoming the inland basin. |
