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。

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.
