| 摘 要： | 准噶尔盆地西北缘上二叠—中侏罗统由下而上可划分为上二叠统上乌尔禾组、下三叠统百口泉组、中三叠统克拉玛依组、上三叠统白碱滩组、下侏罗统八道湾组、三工河组及中侏罗统西山窑组和头屯河组.在10余口井的岩心、岩屑样品分析中,发现5个大孢子组合,通过对主要属种地史分布规律的分析和与国内外各地同时代大孢子组合的对比,将其时代归为晚二叠—中侏罗世.这些大孢子组合的建立和完善,对准噶尔盆地西北缘的地层划分对比及全盆地生物地层工作及油气勘探研究具有深远的意义.

| Abstract: | Late Permian-Middle Jurassic of the north-west area in Junggar basin include Shangwuerhe,Baikouquan,Kelamyi,Baijiantan,Badaowan,Sangonghe,Xishanyao,andToutunhe format-ions. Five megaspores assemblages have been analysed form these formations(expect Baikouquan formation).By analyzing the periods of the important species and genera in the assemblage and comparing with the believed assemblages in various districts,the author coexitent considered that the geologic age of the assemblage was Late Permian-Middle Jurassic .It is greatgrest significance for the stratigraphic and paleontological studies and the petroleum exploration and research in this area . |
