摘要

Based on the evidences of lithostratigraphy, palynology, micropaleontology and geochronology, paleoenvironments since the Late Pleistocene in the study area have been reconstructed. One of the most important inferences is that two marine transgressions have occurred, one in Wurm Sub-interglacial and the other Postglacial. The former had caused the study area to be in an estuary-bay environment over the transgression maximum, with a sea level of no less than 10 m below present; the latter reached its maximum over the Atlantic stage, with sedimentary environments of estuary-bay, bay or shallow sea, and the sea level arrived at the highest elevation in about 6 - 5 ka B. P. Furthermore, it is notable that, during the Late Wurm Glacial, the study area had principally been in an estuary-bay environment, although the climate, like many other areas, turned cold and dry, it reflects a general trend of crustal subduction in Jiulong Estuarine Plain over this period.
