福建晚更新世海侵问题探讨

A DISCUSSION ON PROBLEMS OF MARINE TRANSGRESSION ALONG THE FUJIAN COAST DURING THE LATE PLEISTOCENE

福建沿海在晚更新世大约距今90—80ka、70—60ka、44—39ka和34—20ka期间分别发生过4次海侵。最末一次海侵(距今34—20Ka)期间有过明显的海面下降波动,时间大约在距今28ka前后。

To this day there are still divergences of views on the problems of marine transgression along the coast of Fujian Province during the Late Pleistocene, which include the number of times, age and height in the sea level of the transgression. By synthesized analyses of 6 drill holes with high dense sampling and multitesting along the coast of Fujian, we hold that four marine transgressions took place in the Late Pleistocene about 90-80 ka B. P. , 70-60 ka B. P. ,44-39 ka B. P. and 34-20 ka B. P. respectively in the coastal area of Fujian. However, there was an obvious fall fluctuation about 28 ka B. P. in the sea level during the transgression which occurred about 34-20 ka B. P.
