Figure F4. Sulfate concentrations vs. sulfur isotopic composition for all measured pore water sulfate samples from the Leg 201 sites compiled in Table T1. The insert shows how different processes may influence the composition of dissolved sulfate. 1 = bacterial sulfate reduction, 2 = mixing with sulfate-rich deep brine. V-CDT = Vienna-Canyon Diablo troilite.
