Assessing the robustness of carbonate‐associated sulfate during hydrothermal dolomitization of the Latemar platform, Italy

Carbonate-associated sulfate (CAS) is an important proxy for reconstructing marine sulfur cycling throughout Earth's history. In order to assess the impact of carbonate neomorphism on δ34SCAS data, a mineralogical-spatial transect from early diagenetic limestone into low-temperature hydrothermal dolostone was analyzed in middle Triassic Latemar platform interior, northern Italy. This study addresses yet unconstrained question whether preserves signature and, hence, might represent archive past seawater sulfate. this study, values were measured and compared with data their corresponding precursor limestone. Results shown here reveal that are indistinguishable. points rock-buffered δ34S not affected by alteration. Hence, represents, under favorable conditions, unraveling cycling.
