利用双壳类壳体提取古气候古环境信息是生物碳酸盐研究的热点,而壳体定年一直是研究中的难点。相关研究主要观点是先找到一些时间控制点,再按照线性内插法来确定壳体的时间序列。本文综述了国内外目前双壳类壳体定年的常用方法,根据时间控制点的获得将这些方法归为以下几类:壳体日生长层法、壳体氧同位素法、数字图像技术法和微量元素法,介绍并讨论了每种方法的应用和存在的不足。研究者应该根据具体研究的生物和环境选择适合的方法。
Paleoclimate paleoenvironmental information extraction using bivalve shells is a hot research topic in biocarbonate, and the shell dating has been a difficult point in the research. The main point of the relevant research is to find some time control points, and then determine the shell’s time series according to the linear interpolation method. In this paper, the current methods of dating bivalves at home and abroad are reviewed. According to the timing control points, these methods are classified into the following categories: shell daily growth layer method, shell oxygen isotope method, digital image technique and trace Element method, introduced and discussed the application of each method and its shortcomings. Researchers should choose the appropriate method according to the specific biological and environmental research.
