Abstract:
Bulk silicate Sr-Nd data, extracted from bank and bedload, are from Galy and France-Lanord (2001) (URI:https://doi.org/10.1130/0091-7613(2001)029<0023:HERITH>2.0.CO;2), Singh and France-Lanord (2002) (URI:https://doi.org/10.1016/S0012-821X(02)00822-1), Singh et al. (2008) (URI:https://doi.org/10.1029/2007JF000909). 10Be data are averaged from Lupker et al. (2012, 2017) (URI:https://doi.org/10.1016/j.epsl.2012.04.020) (URI:https://doi.org/10.5194/esurf-5-429-2017). The production rates were computed using Basinga (Charreau et al., 2019) (URI:https://doi.org/10.1002/esp.4649) with the Lal-Stone / ERA40 atmosphere configuration using a sea-level high latitude production rate of 4.18 atom/g/y (Martin et al., 2017) (URI:https://doi.org/10.1016/j.quageo.2016.11.006), factors for different particle production rates of 0.9886 for spallation, 0.0027 for slow muons, 0.0087 for fast muons and attenuation lengths of 260 g/cm2 for slow muons and 510 g/cm2 for fast muons (Braucher et al., 2011) (URI:https://doi.org/10.1016/j.epsl.2011.06.036), and the basins defined in the Methods of the article associated to the dataset.
