摘要: 本文通过沉积垂直序列和沉积年代的分析,探讨晚更世末期以来,辽东半岛东部海侵趋势和沉积环境的变化。

Abstract: Based on the data of drilling sampling,spore-pollen and micropaleontologic analysis,C14 datings and field survey,the authors made a preliminary approach to the characteristics,distribution area,thichness and age of deposits mainly consisting of diluvial-alluvial,lacustrine and marine facies deposits in littoral area of the east Liaodong Peninsula.The deposit environment change since the late stage of the late Pleistocene,and transgression trend in the Holocene were chiefly analysed,for example,the time when transgression began and reached peak,transgression seope,regression time, and frequency and age of intermittent stop of sea level in regression pro-
