Building age model in palaeoenvironmental fluctuation: Introduction and challenges

Abstract

Palaeoenvironmental studies deal with archives, and providing a reliable age model to the archives being studied is the first step in understanding the global environmental system. There are two methodologies to establish an age model for a target archive. One is to compare proxy fluctuations to the series of fluctuations with reliable age model. The other is radiometric dating. We can send our samples to an analytical institute to obtain the data, but understanding the basics of each methodology is important to properly interpret the reported data . Here I introduce the methods used in palaeoenvironmental studies and some of the resent developments.
