| Abstract: | The sediments from the margin-slope zone of the Tertiary Qaidam lake basin in the Ganchaigou region, Qinghai are explored on the basis of surficial investigation and well logs. Five depositional systems have been distinguished: fan-delta, submarine pluvial fan-nearshore turbidity current, braided channel-delta, normal lake-delta and lake depositional systems. The genetic stratigraphic framework and model for the lake basin filling are constructed in terms of temporal-spatial distribution and tectonic-stratigraphic sequences in the Ganchaigou region. |
| Keywords: | depositional system genetic stratigraphic framework model for lake basin filling Qaidam |
