Diagenesis occurring soon after sediment deposition, at low temperature and in relation to the depositional environment has a major impact on the geological records. Processes involved in early diagenesis comprise mineral dissolution, precipitation and replacement, as well as mechanical deformation and chemical alteration. In addition, these processes can be microbially influenced. Early diagenetic processes often reflect oceanographic conditions, while in turn their reaction products may significantly impact global biogeochemical cycles. In this session we welcome oral and poster presentations from multiple fields including sedimentology, mineralogy, geochemistry and biology that contribute to a better understanding of early diagenetic processes. Contributions may include process-oriented studies in modern systems, experiments, mathematical models, and studies of the rock record. The overarching goal is to understand how early diagenesis affected the geological record and how early diagenetic systems co-evolved and interacted with geochemical cycles over Earth’s entire history.
