| 摘要: |
| 通过地面调查及钻井地质资料分析,对柴达木盆地干柴沟地区第三系湖盆边缘斜坡带沉积体系构成进行分析研究,该体系主要由扇三角洲沉积体系,水下洪积扇-近岸浊流沉积体系,辫状河三角洲沉积体系,常态湖三角洲沉积体系和湖泊沉积体系组成。对其成因地层格架及湖盆充填模式进行了探讨分析。 |

| Abstract: |
| The sediments from the margin-slope zone of the Tertiary Qaidam lake basin in the Ganchaigou region, Qing hai are ex plo red on the basis of surficial investigation and well log s. Five depositional sy stems have been distinguished:fan-delta, submarine pluvial fan-nearshore turbidity current, braided channel-delta, norm al lakedelta and lake depositional systems.The genetic stratigraphic framew ork and model for the lake basin filling are constructed in terms of temporal-spatial distribution and tectonic-stratigraphic sequences in the Ganchaigou region. |
| Key words: depositional system genetic stratigraphic framew ork model for lake basin filling Qaidam |
