Holocene Beachrock in Lianyungang of Jiangsu and its Paleogeographic significance

作者在江苏省连云港海滨首次发现了全新世海滩岩，这个发现使我国全新世海滩岩的北界从浙江省长涂岛（３０．２°Ｎ）北移到江苏连云港海岸（３４．９°Ｎ）。文章对连云港中－－晚全新世古气候、海平面变化、水动力条件、古地理环境等作了初步探讨。

Holocene beachrock have been first fond in places along the coast of Lianyungang, Jiangsu Province. Up to now the Lianyungang beachrock is the northmost beachrock in China. The discovery of Holocene beachrock in Jiangsu Province, moves the north limit of Holocene beachrock from the Changtu Island (30.2°N) of Zhejiang Province to Lianyungang coast (34.85°N) of Jiangsu Province. In this paper, the author have made preliminary study to the Middle-Late Holocene changes of sea level, paleoclimate, chang of dynamic condition and paleogeography environments etc.
