Information about macroevolutionary history, past biodiversity, ecology, biogeochemical cycles, climate and environmental change is enclosed in the sedimentary rock record. This information can be extracted with traditional palaeontological, sedimentological and geochemical techniques. Nonetheless, preservation, diagenesis, erosion, sea-level changes, sampling strategies, and analytical approaches can distort this information and introduce biases in the reconstructions of past Earth processes. This problem has gained wider recognition with respect to palaeontological patterns, particularly in the field of stratigraphic palaeobiology addressing the impact of the sequence-stratigraphic architecture on fossil data. However, similar aspects can as well alter geochemical proxy records. For example, diagenetic trajectories specific to certain lithologies can dictate stratigraphic patterns in stable and radiogenic isotope as well as (trace) elemental composition. Hence, approaches that correct for these artifacts in palaeontological, sedimentological and geochemical time series might share many commonalities. We invite contributions that use frequentist statistics, Bayesian statistics, mechanistic models, and machine learning to tackle these problems across different timescales and disciplines, ranging from the Precambrian up to the Holocene, and which contribute to a holistic understanding of the Earth system.
This is a short description of how we will handle our session chat. We have allocated at least 4 minutes of time to discuss individual contributions after a brief introduction (5 minutes). We will finish our session with an open discussion (min. 25 min) allowing for more questions for individual talks (if necessary) as well as more general remarks on topics related with our session.
