Evaluating the S-isotope fractionation associated with Phanerozoic pyrite burial
Abstract
This study examines the sulfur isotope record of seawater sulfate proxies using δ34S and Δ33S to place constraints on the average global fractionation (Δ34Spy) associated with pyrite formation and burial and the exponent λ that relates variations of the 34S/32S to variations of the 33S/32S. The results presented here use an analysis of the sulfur isotope record from seawater sulfate proxies and sedimentary sulfide to extract this quantity as …
