| 摘 要： | 通过对准噶尔盆地阜东斜坡区侏罗系的沉积背景，沉积岩成分，结构、构造及岩性序列等综合研究表明，该区侏罗系具有较好的旋回性，可划分为６个沉积层序和两个构造层序，侏罗系沉积物具有较低的成分成熟度和中等结构成熟度，粒度概率图及沉积构造均显示其具有牵引流沉积特征及三角洲沉积序列。在研究区侏罗系发育南、北两大特源区及方向的水系，据此可识别出辫状河，辫状河三角洲、曲流河、正常三角洲、滑塌浊积扇和湖泊等多种沉积体

| Abstract: | The integration of the data on depositional background,compositions,structures and textures,and lithological sequences has revealed that the Jurassic sediments on East Fukang slope of the Junggar Basin,Xinjiang are cyclically well defined,and may be divided into six depositional sequences and two structural sequences.These sediments have low compositional maturity and moderate textural maturity,and display the depositonal sequences of traction flow deposits and deltaic deposits viewed from grain size probability curves and sedimentary structures.The sources of detritus lay to the north and south,as well as other orientations.The depositional systems consist of braided stream,braided delta,meandering stream,normal delta,fluxoturbidite fan and lake systems. |
