Micro-scale δ34S variation of sulfide species

Project description

Probing sulfur isotope variability in organic sedimentary rocks

The delta 34 S (δ34S) value is a standardised method for reporting measurements of the ratio of two stable isotopes of sulfur, 34S:32S, in a sample against the equivalent ratio in a known reference standard. The method has been widely used to reconstruct the paleo-redox conditions of early Earth environments. Existing δ34S compilations of sulfur isotopes on pyrite rocks possibly do not reflect the accurate isotope composition deposited on the rock. The EU-funded MicroS project will use high-resolution in situ analytical methods – secondary-ion mass spectrometry and X-ray spectroscopy – to investigate micro-scale δ34S variability in organic-rich sedimentary rocks. The project's work will help increase our understanding of the processes that govern sulfur isotope fractionations, δ34S transfer to the rock record and its preservation over the geologic time scale.
