Sulfur isotopes in diamonds reveal differences in continent construction

Science, 2019
Sulfur tells tectonic secrets Plate tectonics dominates how the surface of Earth is shaped over geologic time; however, we do not know when this important process started on Earth. Smit et al.

Sulfur Isotope Evidence for a Geochemical Zonation of the Samoan Mantle Plume

Geochemistry, Geophysics, Geosystems, 2021
Basalts from the Samoan volcanoes sample contributions from all of the classical mantle endmembers, including extreme EM II and high 3He/4He components, as well as dilute contributions from the HIMU, EM I, and DM components.

Shell structure underlying the evolution of quadrupole collectivity in S-38 and S-40 probed by transient-field g-factor measurements on fast radioactive beams [PDF]

, 2006
The shell structure underlying shape changes in neutron-rich nuclei between N=20 and N=28 has been investigated by a novel application of the transient field technique to measure the first-excited state g factors in S-38 and S-40 produced as fast ...

Sulfur isotopes in rivers: Insights into global weathering budgets, pyrite oxidation, and the modern sulfur cycle

Earth and Planetary Science Letters, 2018
The biogeochemical sulfur cycle is intimately linked to the cycles of carbon, iron, and oxygen, and plays an important role in global climate via weathering reactions and aerosols. However, many aspects of the modern budget of the global sulfur cycle are

Crustal Mercury Addition Into the Giant Jinchuan Ni‐Cu Sulfide Deposit, China, and Its Geological Implications

Geochemistry, Geophysics, Geosystems, 2022
Mercury (Hg) isotopes have shown their power of tracing Hg pollution sources in ecosystems, but their potentials for petrogenetic tracing are yet to be explored.

Large sulfur isotope fractionations in Martian sediments at Gale crater [PDF]

, 2017
Variability in the sulfur isotopic composition in sediments can reflect atmospheric, geologic and biological processes. Evidence for ancient fluvio-lacustrine environments at Gale crater on Mars and a lack of efficient crustal recycling mechanisms on the

Off limits: sulfate below the sulfate-methane transition

Frontiers in Earth Science, 2016
One of the most intriguing recent discoveries in biogeochemistry is the ubiquity of cryptic sulfur cycling. From subglacial lakes to marine oxygen minimum zones, and in marine sediments, cryptic sulfur cycling – the simultaneous sulfate consumption and ...

A review of volatiles in the Martian interior [PDF]

, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

Nature of isomerism in exotic sulfur isotopes. [PDF]

Physical Review Letters, 2014
We clarify the origin of the anomalously hindered E2 decay from the 4_{1}^{+} level in ^{44}S by performing a novel many-body analysis in the shell model.

Tetrathionate and Elemental Sulfur Shape the Isotope Composition of Sulfate in Acid Mine Drainage

Frontiers in Microbiology, 2017
Sulfur compounds in intermediate valence states, for example elemental sulfur, thiosulfate, and tetrathionate, are important players in the biogeochemical sulfur cycle.
