| 中文摘要: |
| On the basis of the analysis and study of the records of shallow-layer profiles and information from systematic analyses of some cores and their 14C datings,the sediments of Yellow Sea trough since the final slage the Late Pleistocene are found to have the following features.On the south slope of the trough,it is probably composed of island-shelf de posits.On the mouth of the trough,it is made up of eolian dunes and its deposits.In the central bottom region of the trough where intense desertization occurred in the early stage of the regression,there are parallel oblique beddings in the strata known as the "angle of repose" texture,which demonstrates that the deposits there are composed of eolian sands.And in the late stage,thin derivative deposits developed in the northern part of the trough.On the north slope of the trough,thick-layer derivative deposits developed.This primary sedimentary pattern still remains unchanged since the occurrence of the Holocene transgression. |
