Abstract The Steptoean Positive Isotopic Carbon Excursion (SPICE) is a prominent
chemostratigraphic feature in the Lower Paleozoic. It has been used to correlate Upper …

The present study reviews the main geochemical, sedimentological, and paleontological
events associated with one of the largest perturbations in the Phanerozoic carbon cycle, the …

Understanding variation in the sulfur isotopic composition of sedimentary pyrite (δ34Spyr) is
motivated by the key role of sulfur biogeochemistry in regulating Earth's surface oxidation …

The Paleoproterozoic Lomagundi–Jatuli Event (LJE) is generally considered the largest, in
both amplitude and duration, positive carbonate C-isotope (δ 13Ccarb) excursion in Earth …

The δ34S of seawater sulfate reflects processes operating at the nexus of sulfur, carbon, and
oxygen cycles. However, knowledge of past seawater sulfate δ34S values must be derived …

It is well documented that Upper Ordovician and Silurian successions record multiple marine
turnover events–including the second-largest mass extinction in the Phanerozoic …

The early Silurian Llandovery–Wenlock boundary interval is marked by significant marine
perturbations and biotic turnover, culminating in the Ireviken Extinction Event and the Early …

Abstract Several Late Devonian sedimentary successions host pyrite with highly positive
sulfur isotope values (δ 34 S pyrite). These anomalous values have been linked to marine …

Abstract The Llandovery–Wenlock carbonate-marl succession of the Baltoscandian Basin
has been analyzed in the Viki drill core, western Estonia, for carbonate carbon (δ 13 C carb) …

Abstract The Ediacaran Shuram excursion (SE) records a global decrease in carbonate
carbon isotope (δ 13 C carb) values from+ 6‰ down to ca.–10‰, representing the largest δ …
