Sulfur isotopes reveal agricultural changes to the modern sulfur cycle

open access: yesEnvironmental Research Letters, 2022
The environmental fates and consequences of intensive sulfur (S) applications to croplands are largely unknown. In this study, we used S stable isotopes to identify and trace agricultural S from field-to-watershed scales, an initial and timely step ...

Geochemical transformations of sulfur in salt lakes (Transbaikalia) [PDF]

open access: yesE3S Web of Conferences, 2023
The water column in brackish and saline lakes hosts various forms of sulfur including sulfide (hydrosulfide), elemental, thiosulfate, and sulfate sulfur.

Analysis of Sulfur Isotope Composition of Gypsum Samples by Elemental Analyzer-Isotope Mass Spectrometry

open access: yesYankuang ceshi, 2020
BACKGROUND The conventional method for the measurement of sulfur isotopes in sulfate includes mainly barite conversion coupled with dual-inlet SO2 methods. These methods are facile and reliable.

Sulfur isotopes in Finnish nickel-copper occurrences [PDF]

open access: yesBulletin of the Geological Society of Finland, 1980
The sulfur isotope composition of the Hitura, Kotalahti and Kylmäkoski Ni-Cu ores was analyzed. The results have been compared with earlier sulfur isotope analyses of the Vammala, Laukunkangas and Oravainen Ni-Cu occurrences. Altogether 183 analyses were

Nature of Isomerism in Exotic Sulfur Isotopes [PDF]

open access: yesPhysical Review Letters, 2015
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. Within a unified picture about the occurrence of isomerism in neutron-rich sulfur isotopes, the $4^+_1$ state is demonstrated to be a $K=4$ isomer dominated by the two-quasiparticle configuration ...

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism

open access: yesGeophysical Monograph Series, Page 247-262., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Hartree-Fock-Bogoliubov Calculations in Coordinate Space: Neutron-Rich Sulfur, Zirconium, Cerium, and Samarium Isotopes [PDF]

open access: yes, 2003
Using the Hartree-Fock-Bogoliubov (HFB) mean field theory in coordinate space, we investigate ground state properties of the sulfur isotopes from the line of stability up to the two-neutron dripline ($^{34-52}S$).

A Critical Look at the Combined Use of Sulfur and Oxygen Isotopes to Study Microbial Metabolisms in Methane-Rich Environments

open access: yesFrontiers in Microbiology, 2018
Separating the contributions of anaerobic oxidation of methane and organoclastic sulfate reduction in the overall sedimentary sulfur cycle of marine sediments has benefited from advances in isotope biogeochemistry.

Holocene Spatiotemporal Redox Variations in the Southern Baltic Sea

open access: yesFrontiers in Earth Science, 2021
Low oxygen conditions in the modern Baltic Sea are exacerbated by human activities; however, anoxic conditions also prevailed naturally over the Holocene. Few studies have characterized the specific paleoredox conditions (manganous, ferruginous, euxinic)

Folding model analysis of elastic and inelastic proton scattering on Sulfur isotopes [PDF]

open access: yes, 2002
The folding formalism for the nucleon-nucleus optical potential and inelastic form factor is applied to study elastic and inelastic proton scattering on 30-40S isotopes. A recently developed realistic density dependent M3Y interaction, well tested in the
