EXPLEHING THE HOLOCENE TRANSGRESSION TREND ON THEBASIN OF SAND MOUND NEAR LIUGU RIVERESTUARY IN WESTERN LIAONING |
| |
| Abstract: | Holocene transgression trend in the near-shore of western Liaoning was studied on the basis of sand accumulation geomorphy and sedimentary character. The data 14C show that transgression had taken place in this region 8000-7000 years ago, the river valley was flooded, sea water reached as far as 5 to 10 km upstream but no more than 20 km, equivalent to 5 to 7 m above the normal sea level. Thickness of marine phase was from 20 km to 25 km. Sea water regressed in 5000-4000 B. P. |
