Carbonate sediments form in marine and non-marine settings through a complex interaction of biological, chemical and physical processes that make them sensitive recorders of climatic, oceanographic and environmental changes. The identification and study of Recent analogues for ancient marine and non-marine carbonate systems is crucial to the interpretation of these systems. Conversely, precisely-constrained high-resolution stratigraphic records are important for determining past global change and detailing the interactions between climatic processes, the biosphere and stratigraphic architecture. This session will explore a range of geochemical, biological and stratigraphic proxies and their applications to understanding Earth history.
