Abstract

For a provenance study and characterization of different types of sedimentological processes that affect weathering, information on chemical weathering of sediments is critical. Major elements of sedimentary geochemistry can be estimated by using the various weathering indices (WIs) models. The present study is a fair attempt in the development of a web dashboard–SedWeather to analyze chemical weathering of sediments using major elemental geochemistry. It offers a flexibility to constrain sediments and rock composites and to demonstrate weathering profiles & source rock chemical makeup in various compositional space diagrams including Al2O3–CaO-Na2O–K2O, Al2O3–CaO-Na2O-K2O–Fe2O3-MgO, M–F–W; illustrates different various weathering indices (WIs) including CIW, CPA, CIA, PIA, CIX, ICV, WIP and W in boxplots, scatter matrix, correlation matrix against major oxides and ratios. It is possible to alter the Python code in accordance with the data and user requirement by altering the arguments and adding more relevant charts and plots to fit the data. SedWeather’s performance in evaluating chemical weathering is demonstrated by evaluating sediments of Surma and Barail sandstones, Mizoram Foreland Basin, NE India, sediments of Manasbal lake, Kashmir, India, and channel sediments, overbank sediments, suspended sediments of the Ganga basin, having their own provenance history.
