扶余县长春岭油页岩矿含矿岩系地质特征及沉积环境分析

Geologic features and sedimentary environment of the Changchunling rock series with oil shale,Fuyu County

扶余县长春岭油页岩矿层绝大多数赋存于白垩系下统青山口组下部层位,少数矿层产在白垩系上统嫩江组第一、二段内,另有一部分矿层(油砂层)产于泉头组顶部。通过对含矿岩系沉积岩石颜色、构造、韵律组合及古生物的分析,推测青山口组为浅湖-深湖-半深湖环境;姚家组为半深湖--浅湖环境;嫩江组属浅湖-深湖-半深湖-滨湖环境。

Most of Changchunling oil shale occurs in the lower of Qingshankou Formation,the lower series of the Cretaceous,a few ore beds occur in the first,second layers of the Nenjiang Formation,the upper series of the Cretaceous,the other ore bed(oil sand layer) occurs in the top of the Quantou Formation.Through the analysis of the color of sedimentary rock bearing oil shale,structure,rhythmic succession and paleontology,it was inferred that Qingshankou Formation belongs to shallow lake-deep lake-half deep lake env...
