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.

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 ...

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

Modification of Elemental Analysis-Stable Isotope Ratio Mass Spectrometer Combined Instrument for Determination of Sulfur Isotopes in Solid Samples

open access: yesJournal of Isotopes, 2021
In this paper, the elemental analysis-stable isotope ratio mass spectrometer (EA-IRMS) is modified to testing different forms of sulfur isotope standard material and sample.

Fractionation of sulfur isotopes by Desulfovibrio vulgaris mutants lacking hydrogenases or type I tetraheme cytochrome c3

open access: yesFrontiers in Microbiology, 2013
The sulfur isotope effect produced by sulfate reducing microbes is commonly used to trace biogeochemical cycles of sulfur and carbon in aquatic and sedimentary environments.

Sulfur and Oxygen Isotope Records of Sulfate-Driven Anaerobic Oxidation of Methane in Diffusion-Dominated Marine Sediments

open access: yesFrontiers in Earth Science, 2022
Organoclastic sulfate reduction (OSR) and sulfate-driven anaerobic oxidation of methane (SD-AOM) are the two major microbial pathways for sulfate consumption in marine sulfur cycle.

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

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

Sulfur isotope signatures of sulfides from the Khibina and Lovozero massifs (Kola Alkaline Province, Fennoscandian Shield)

open access: yesVestnik MGTU, 2021
The sulfur isotope geochemistry of the Khibina and Lovozero agpaitic massifs provides an opportunity to understand the role of plume-lithosphere interaction processes responsible for the Paleozoic alkaline igneous activity in the north-eastern part of ...

Fire and brimstone: the microbially mediated formation of elemental sulfur nodules from an isotope and major element study in the paleo-Dead Sea.

open access: yesPLoS ONE, 2013
We present coupled sulfur and oxygen isotope data from sulfur nodules and surrounding gypsum, as well as iron and manganese concentration data, from the Lisan Formation near the Dead Sea (Israel).
