【摘要】 通过对准噶尔盆地层序界面、首次洪泛面和最大洪泛面的识别,建立了侏罗系层序地层格架,划分出2个超层序、7个层序和15个体系域. 其识别标志为地震、露头、钻测井资料上的特征,结合构造运动界面、不整合界面、古土壤层及岩性突变等. 分析了侏罗系层序形成的主控因素,即构造运动和沉降、物源供应、湖平面升降和气候条件等.更多还原

【Abstract】 To classify the Jurassic sequence stratigraphy in Junggar basin, the basic foundations are sequence boundary, the first flood plane and the most flood plane. The identification including seismic, outcrop and the character of drilling and logging data, combined with the structure movement interface. The unconformity, antique soil layer, lithologic mutation and so on. To build the framework of Jurassic sequence stratigraphy includes the classification of two super-sequences, seven sequences and fifteen system tracts. The dominating factors are the moment of structure and subsidence, the supplying of resource, the rising and falling of lake’s surface and the climate condition.更多还原
