Provenance and Tectonic Evolution of Bauxite Deposits in the Tethys: Perspective From Random Forest and Logistic Regression Analyses

Developments in Earth system research have led to widespread interest multi-sphere interactions that may controlled bauxite formation. Although karst ores are abundant the Tethyan Metallogenic Domain (TMD), their genesis and distribution not yet fully understood. This study utilizes Random Forest (RF) model analyze geochemical data sets compiled from three provinces Tethys, including Mediterranean, Central Asian, Chinese provinces. Meaningful variables among provenance, paleolatitude tectonic setting affected formation of deposits identified. The Logistic Regression is used verify importance various factors. Our shows when RF achieves best classifier performance, TiO2 variable has greatest impact on model. content highest Asian Province. high bauxites indicates a provenance magmatic origine associated with Subduction Provenance Zone. Bauxites similar continental basement derived siliciclastic carbonate rocks, identified as Orogenic illustrates novel link between compositions (TiO2 content) bauxites, regional setting.
