Isotopic composition of sulfur and sulfate produced by oxidation of FeS
John S. Lewis,H. Roy Krouse +1 more
TLDR
Sulfate enriched in 32 S with respect to co-existent sulfur is found in the Orgeuil meteorite as discussed by the authors, which can be effected with at least three laboratory procedures: (1) oxidation of FeS by traces of a strong oxidizing agent such as O 2 or HOOH in a generally reducing aqueous environment, (2) bacterial oxidation of sulfides, or (3) reaction of elemental sulfur with water followed by partial oxidation of the unequilibrated products.About:

Carbonaceous chondrites. II - Carbonaceous chondrite phyllosilicates and light element geochemistry as indicators of parent body processes and surface conditions
Ted E. Bunch,Sherwood Chang +1 more
TL;DR: Petrographic analyses of CM matrices characterized four phyllosilicates in Murray and Murchison meteorites and Fe- and Mg-serpentines in Nogoya as discussed by the authors.

Stable isotope geochemistry of acid mine drainage: Experimental oxidation of pyrite
TL;DR: In this paper, sulfate and water from experiments in which pyrite was oxidized at a pH of 2.0 were analyzed for sulfur and oxygen stable isotopes, and experiments were conducted under both aerobic and anaerobic sterile conditions, as well as under aerobic conditions in the presence of Thiobacillus ferrooxidans to elucidate the pathways of oxidation.

Low temperature condensation from the solar nebula
TL;DR: In this article, two models of the low temperature condensation accretion process for different extreme assumptions are investigated, and the results of these models are compared and their relevance to processes in the solar nebula is discussed.

Brine volcanism and the interior structures of asteroids and icy satellites
TL;DR: Brine vulcanism, in which MgSO4 and Na2SO4 are shown by carbonaceous chondrite mineralogies and elemental abundances to be the most important solutes, is presently suggested to account for the resurfacing observed on such icy satellites as Europa and Ganymede, and to have been a significant factor in the evolution of chondritic asteroids.

Interpretation of sulfur and oxygen isotopes in biological and abiological sulfide oxidation
Laura Toran,R. F. Harris +1 more
TL;DR: In this paper, a new classification scheme for sulfide oxidation based on whether the electron transfer involves incorporation of oxygen from H2O or O2 in the sulfate was developed.

Sulphur isotope geochemistry
TL;DR: In this article, the S 32 /S 34 ratio for meteorites is discussed as a possible base level from which fractionation in the earth's crust began and the value is compared with estimates of average values found for terrestrial samples including some recent results of igneous intrusives.

The kinetic isotope effect in the bacterial reduction and oxidation of sulfur
Nobuyuki Nakai,M. L. Jensen +1 more
TL;DR: The kinetic isotope effect in the bacterial reduction of sulfate to sulfide and oxidation of native sulfur and sulfide to sulfate has been investigated at the temperature of 32°C as mentioned in this paper.

34S/32S ratios for the different forms of sulphur in the Orgueil meteorite and their mode of formation
TL;DR: It is shown that the distribution of the sulphur isotopes found for the Orgueil meteorite sulphur compounds would be compatible with the assumption that a uni-directional, low-temperature reaction between elemental sulphur and liquid water has led to the formation of both troilite sulphurs and sulphate sulphur or their precursors.
