Abstract: In this paper,the authors introduced the Holocene beachrock,that was first discovered in Juexi town of Xiangshan country of Zhejiang’Province in 1988,preliminarily investigated its petrographic character,¹⁴C isotopic age and formative circumstance. Probably,the Juexi beachrock is the northmost Holocene beachrock in China. From ¹⁴C dating of the beachrock,the authors inferred the relative rate of subsidence in this coast for 0.51 mm/a.

Key words: Holocene, Beachrock, Zhejiang, Storm surge

摘要： 作者于浙江象山爵溪首次发现了全新世海滩岩,并对其岩石学特征、同位素年龄、形成环境等进行了初步研究。爵溪海滩岩目前是我国分布位置最北的全新世海滩岩,据¹⁴C年龄测出该地3400多年来海岸的相对沉降速率为0.51mm/a。
