For the Bengal Fan samples, the measurements of major and trace elements were performed at SARM (Nancy, France), following (Carignan et al., 2001) (URI:https://doi.org/10.1111/j.1751-908X.2001.tb00595.x) procedure and using ICP-OES iCap6500 for major element and Sc concentrations, and ICP-MS iCapQ for trace elements. For the Lower Meghna sand, data for major elements are from Lupker et al. (2013) (URI:https://doi.org/10.1016/j.epsl.2013.01.038) and data for trace elements are unpublished data from France-Lanord and Galy and measured similarly than our data. Empty cells indicate measurements below detection, except for commented lines.
