摘要
利用孢粉、微量元素、微古生物、有机质类型和岩石矿物资料对吐哈盆地台北凹陷侏罗系的古气候、古水介质、古水深及物源进行了分析，利用岩心及分析化验资料和电性资料等对沉积相待征进行了研究，将其划分出曲流河、辫状三角洲、三角洲、湖底扇、风暴相等六种沉积相类型，并总结出湖泊沉积体系、冲积扇－辫状河将状三角洲－湖泊沉积体系及冲积扇－辫状河－曲流河三角洲－湖泊体系三种沉积相模式，三种沉积相模式反映了该凹陷在侏罗统沉积时期的主要沉积相的组合特征。
The sedimentary environment, such as paleo climate, paleo-water property.paleo-water depth and the source area,was analysed by usi ng the data of pollen,rareelements,paleotology,type of organic material and minerology. The sedlmentarv facies wasstudied with the data of core and others.Six sedimentarv facies,such as meander river.braided deIta,deIta,deep water fan and tempestite are classified.Three kinds of sedimentaryfacies are established.
