摘要
依兰—伊通地堑和松辽盆地在沉积特征方面相似,巨大的沉积厚度,粗—细不同的碎屑岩系及碎屑成分成熟度低,反映了强烈下陷快速堆积的特点。沉积物中韵律性、旋回性在横向及纵向上岩性、岩相和厚度都有急剧的变化。通过该断陷内伊通大孤山油页岩矿地质特征的认识与了解,对研究省内其他盆地油页岩矿的成矿规律有着重要的指导意义。
Graben from Yilan to Yitong is similar to Songliao basin in depositional characteristics,that is,large depositional thick,clastic rock from macrograin to finegrain and clastics of the low compositional maturity,which reflect characteristics of highly sag and rapid accumulation.The rhymes and cycles in sediments,lithologic characteristics,rock facies and thick in horizontal and vertical are all rapid change.After understanding and knowing the geologic characteristics of oil shale deposit in Dagushan,Yitong,i...
