Reconstruction of environmental changes throughout Earth-history is of great importance for understanding climate dynamics of the Earth-system and the prediction of possible future climate scenarios. Authigenic (bio)minerals play key roles as archive for climate changes, perturbations of global biogeochemical cycles and major extinction events. In this session we address all aspects related to (paleo)environmental and (geo)forensic studies based on biogenically and/or inorganically induced mineral formation, such as nucleation and growth mechanisms/kinetics, reaction pathways, parameters controlling geochemical signatures, preservation and diagenetic alteration as well as paleoenvironmental records. The aim of the session is to present new developments, refinements based on field, experimental and modelling approaches, and to evaluate potential applications as proxy-signals. We encourage contributions from different subdisciplines studying sedimentary archives under diverse perspectives spanning from field to lab studies.
