【摘要】 本文是对阜新煤田含煤沉积进行古植物地层学研究的初步结果,据煤田各含煤组的植物化石分布规律,划分出沙海组Czekanowskia rigida—Otczamiteis linguifolius组合,海州组高德—太平段Elatides harrisii—Pseudolarix sinensis组合,海州组中间段Ginkgoites sibiricus-Acanthopterisgothani组合,海州组孙家湾段Acanthopteris gothani—Ecgymncarpum sinensis组合,水泉组Ctenis lyrata——Sagencpteris liacxiersis组合.建立了水泉组.此外描述了新种“Pseudolarix”sinensis sp nov.和本区首次发现的Elatides harrisii Zhcu(MS),Osmunda of.cretaceaSamylina,Nilssonia Schaumburgensis(Dunker)Nath.更多还原

【Abstract】 In this article, the author deals with the Lower Cretaeous strat-egraphy and plant fossils from Fuxin coal-basin in west Liaoning province. The stratigraphic seguences studied include (in ascending order) Shahai formation, Haizhou formation and the newly established Shuiquan Formation. According to the verticle distribution of the plant fossils, the early Cretaceous Flora in Fuxin have been subdivided, into 5 assemblagd (in ascending order):(1) Czekanowskia rigdia-Otozamites linguifolius assemblage inin Shahai Fr.(2) Elatides harrisii-"Pseudolarix"sinensis assemblage in Gaode-Taiping Member, Haizhou Fr.(3) Ginkgotes sibiricus-Acanthopteris gothani assemblage inZhongjian member, Haizhou Fr.(4) Acanthopteris gothani-Eogymnocapium sinensis assemblagein Sunjiawan Member, Haizhou Fr.(5) Ctenis lyrata-Sagenopteris liaoxiensis assemblage in ShuiquanFr.In additon new species "Pseudolarix" sinensis sp. nov.aome other species which are firstly found from the basin such as Elatides harrisii Zhou (MS), Osmunda cf. cretacea Samlina, Nilssonia, schamburgensis (Nunker) Nath. Two species formcierly studied by the author are also revised as Podocarpus fuxinensis (Shang) Wang, ot Shang, Torreya haizhouensis (Shang) Wang et Shang.更多还原
