A newly discovered hydrothermal field, named Yunzang and predominantly hosted by mafic
rocks, was recently identified at 25.3° S on the South Mid-Atlantic Ridge (SMAR). This is the …

Sulfur (S) isotopes are used to trace metabolic pathways associated with biological S-
cycling in past and present environments on Earth. These pathways (sulfate reduction, sulfur …

Continents are unique to Earth and played a role in coevolution of the atmosphere,
hydrosphere, and biosphere. Debate exists, however, regarding continent formation and the …

In this study, we present quadruple sulfur isotope values (QSI: 32 S, 33 S, 34 S, 36 S)
measured in sediments from two sulfur-rich Mars analogue environments: i) the glacially-fed …

Seafloor hydrothermal chimneys are significant metal resources and have fundamental
effects on marine chemistry balance. Previous studies on growth of the chimneys focused on …

Mangaia, an ocean island in the Cook‐Austral volcanic chain, is the type locality for the
HIMU mantle reservoir and has also been shown to exhibit evidence for recycled sulfur with …

Carbonate concretions accompanied by elemental sulfur were found in an early Messinian
(Late Miocene) marine succession of NW Italy. The rocks were studied with an integrated …

Seafloor hydrothermal sulfides at slow-spreading mid-ocean ridges (MORs) are of economic
and scientific significance. The formation of newly discovered submarine hydrothermal …

Stable isotope compositions of biologically cycled elements encode information about the
interaction between life and environment. On Earth, geochemical biomarkers have been …

Context. Carbonaceous chondrites have undergone alteration in their parent bodies and
display oxidized secondary phases, including sulfates in CI and CM chondrites. The cause …
