| 摘 要： | 辽东本溪田师傅和新开岭地区出露的一套沉积碎屑岩,范国清(1982年)称为东营坊组,时代隶属晚侏罗世。本文依据 Euestheria ziliujinensis 群将东营坊组时代置于中侏罗早中期,与辽西海房沟组、冀北九龙山组叶肢介动物群主体基本一致。依据 Pagiophyllum cf.maculosum,P.cf.shahoziensis,Brachyphyllumcf.mamillare,Coniopteris sp.等植物化石和区域地层接触关系,东营坊组应置于转山子组、大堡组和三个岭组之上。

| Abstract: | Exposed in Tianshifu and Xinkailing of Benxi,E.Liaoning,a set of sedimentary clastic rocks was called Dongyingfang Formation of Late Jurassic by Fan Guoqing in 1982.According to Euestheria ziliujinensis,the paper considered that the age of Dong- yingfang Formation was early-middle stage of Middle Jurassic,similar with Haifenggou Formation in W.Liaoning and Jiulongshan Formation in N.Hebei.Based on the contact relationship of regional strata and flora fossil such as Pagiophyllum cf.maculosum,P. cf.Shahoziensis,Brachyphyllum cf.mamillare,Coniopteris sp.,Dongyingfang For- mation should be put upon Zhuanshanzi Formation,Dapu Formation and Sangeling Formation. |
