Fig. 4: Plots of δ7Lifluid and δ13Ccarb values of the authigenic carbonate.
From: Lithium isotopes trace silicate weathering-driven authigenic carbonate formation in marine sediments
Weak positive correlation of δ7Lifluid and δ13Ccarb values for authigenic carbonates resulting from OSR (organoclastic sulphate reduction), and lack of such correlation in carbonates resulting from sulphate-driven AOM (anaerobic oxidation of methane).
