摘要
根据碎属矿物(长石、石英、岩屑)的标型特征,各碎屑成份的百分含量、重矿物的组合及其平面分布和垂向变化,提出松辽盆地侏罗系碎屑岩的母岩岩性,并分析沉积物的形成条件和形成过程。
The lithological characteristics of the Jurassic elastic host rocks in the Songliao Basin are obtained on the basis of the typical features of the debris minerals (quartz, feldspar and debris), their percentage contents, the association of the heavy minerals and their horizontal distributions and vertical variations, and the forming conditions and courses of the sediments and sedimentary basins are analysed.
