Abstract

The isotope composition of endogenic and biogenic carbonates and diatom silica are commonly used as palaeoclimate proxies from lake and ocean sediments. This talk reviews the controls on the isotope composition of lacustrine skeletal and non-skeletal deposits and illustrates how stable isotope studies contribute to an understanding of environmental and climate change. There are differences in the palaeoclimate potential of different types of sediments which will be investigated. A number of recent case studies will be presented from across the globe.
