| 摘 要： | 根据野外露头、岩心观察及录井、测井资料,研究了柴北缘西段新近系上干柴沟组沉积相类型和沉积特征。结果表明：上干柴沟组发育冲积扇、扇三角洲、辫状河、辫状河三角洲、湖泊及颗粒流等六种沉积相类型,其中在鄂博梁-冷湖-潜西发育了一套扇三角洲-湖泊沉积体系,在马海-南八仙地区发育冲积扇-辫状河-辫状河三角洲-湖泊沉积体系。

| Abstract: | The examination of the sedimentary facies is based on the field outcrops,core observation and well logs for the Neogene Upper Ganchaigou Formation on the northern margin of the Qaidam Basin,Qinghai.The Upper Ganchaigou Formation is built up of the alluvial fan,fan delta,braided stream,braided delta,lacustrine facies and grain flow deposits.Two depositional systems have been recognized,including the fan delta-lacustrine depositional system in the Eboliang-Lenghu-Qianxi zone,and alluvial fan-braided stream-br... |
