| 摘 要： | 野外地质调查和岩石学、地球化学研究表明:喀左盆地3个油页岩层群分别发育于下白垩统九佛堂组的一、二、三段,以位于三段的第三油页岩层群的工业意义最大;油页岩常与上覆沉凝灰岩或其它凝灰质岩石呈伴生关系.油页岩(矿石)类型有泥岩、具粉砂质条带的含钙-钙质泥岩、泥灰岩和页岩4种类型,以前两者为主;低品级油页岩体积分数为50%,中品级油页岩体积分数为42%,高品级油页岩体积分数为8%,均属高灰分油页岩.油页岩的有机质类型为腐植-腐泥型,源于低等植物;浅湖-半深湖形成的油页岩(矿石)类型为含粉砂质条带的含钙-钙质泥岩,深湖形成的油页岩(矿石)类型主要为泥岩;物源区母岩类型对油页岩的化学成分特征及灰分成分类型具有明显的控制关系;火山喷发的灾变事件终止了油页岩的成矿作用.

| Abstract: | Field geological investigation,petrology and geochemistry study showed that three oil shale groups in Kazuo basin were developed in Member 1,2,3 of the Jiufotang Formation of Lower Cretaceous,the third oil shale group located in 3rd member have the greatest industrial significance.Oil shale always has the accompanying relationship with overlying sedimentary tuff or other tuffaceous strata.The oil shale(ore) of this area have four types,including mudstone,calcareous mudstone containing silty band,marlite and... |
