Carbonate (bio)minerals have played an essential role in the history of life on Earth, forming one of the most important archives for past climate and environmental change. Geochemical investigations have been crucial for understanding the evolution of microbial habitats and the paleobiology of carbonate biomineralizers since the Precambrian. With this session, we encourage contributions from sedimentology, geochemistry and biology that utilize carbonate (bio)minerals (e.g., microbialites, mollusk shells, and foraminifera) with the aim to reconstruct past environments, seasonality, seawater chemistry, and paleobiology in a wide range of modern to deep time settings, including critical intervals of environmental and climatic change. This includes theoretical or experimental studies of trace element partitioning and isotope fractionation and studies into original skeletal carbonate preservation and diagenetic alteration.
