Sulfur Isotopes in Stromatolites
2011Intense biological sulfur cycling characterizes modern marine microbial mats as well as their ancient counterparts – stromatolites. Respective microbially driven processes, such as bacterial sulfate reduction, sulfide oxidation, or the disproportionation of sulfur-bearing compounds of intermediate oxidation states, are associated with distinctive and ...

Physical Review, 1958
A new isotope of sulfur, ${\mathrm{S}}^{38}$, has been produced by the ($\ensuremath{\alpha}, 3p$) reaction on ${\mathrm{Cl}}^{37}$. It was found to have a half-life of 172\ifmmode\pm\else\textpm\fi{}1 minutes, and to decay by the emission of two beta groups with end-point energies of 1.1 and 3.0 Mev.

Sulfur isotopes and mineral paragenesis
Economic Geology, 1957Almost all of the previous investigations of S 32 /S 34 ratios of sulfide minerals and ores have indicated a lack of significant variations in the ratios of specimens collected from one deposit. Most of these valuable previous studies have been done by non-geologists upon, unfortunately, limited and poorly representative mineral suites of sulfide ...

Sulfur Isotopes by Ion Microprobe
1997Abstract Over the last decade, secondary ionization mass spectrometry (SIMS, or the ion microprobe) has been applied to a wide variety of areas in the geosciences. In this technique, a collimated beam of primary ions is accelerated onto the sample, and the secondary ions that result from the sputtering of the sample are extracted for ...
