“…Correction methods used by the individual authors typically rely on ratios of Ca-Na and Mg-Na (Gaillardet et al, 1999b). Data are from multiple sources (Carey et al, 2006;Gabet et al, 2010;Gaillardet et al, 1997;Gaillardet et al, 1999b;Gibbs, 1967;Goldsmith et al, 2008;Grove, 1972;Guyot et al, 1996;Hartmann and Moosdorf, 2011;Li et al, 1984;Lyons et al, 2005;Moquet et al, 2011;Mortatti and Probst, 2003;Qin et al, 2006;Schaller et al, 2001;Wolff-Boenisch et al, 2009). 8 Silicate weathering fluxes from volcanic lithologies, corrected for atmospheric and, where possible, for hydrothermal inputs (Gaillardet et al, 2011).…”
