摘要： 本文基于对平地泉组化石古生物、岩性、特征矿物和微量元素等方面的研究,认为平地泉组沉积时期的沉积环境为陆缘近海湖。并指出在一套表征古盐度值较高的特殊动物群大量死亡富集的层位附近寻找物性较好的扇三角洲砂砾岩体为盆地东部油气勘探的重要方向。并把平地来组与南缘芦草沟组至红雁池组和西北缘下乌尔禾组进行对比。

Abstract: Based on the fossil assemblages lithologic characters, special minerals and microelements etc. , the depositional environment in the period of Pingdiquan formation was recognized to be a continental shore paralic lake, and expioring fan delta sandy—conglomeratic bodies to be good in petrophysics in the vicinity of strata that showed higher paleao—salineness and enormously enriched special fauna will be an important direction for prospecting hydrocarbon from east part of Junggar Basin. This paper also gives correlations for Pingdiquan formation, Lucaogou—hongyanchi formations in the southern margin and Lower Wuerhe formation in northwestern margin .
