Considered esoteric only a few years ago, research into the stable isotope geochemistry of transition metals is moving into the geoscience mainstream. Although initial attention focused on the potential use of some of these nontraditional isotope systems as biosignatures, they are now emerging as powerful paleoceanographic proxies. In particular, the Fe and Mo isotope systems are providing information about changes in oxygenation and metal cycling in ancient oceans. Zn, Cu, Tl, and a number of… Expand

Stable isotopes are tools that geobiologists use to investigate natural and experimental systems, with questions ranging from those aimed at modern environments and extant microorganisms, to deep… Expand
Potential of non-traditional isotope studies for bioarchaeology
As a consequence of recent developments in mass spectrometry, the application of non-traditional stable isotope systems (e.g. Ca, Cu, Fe, Mg, Sr, Zn) as well as radiogenic isotopes to archaeological… Expand
Iron isotopes in an Archean ocean analogue
Abstract Iron isotopes have been extensively used to trace the history of microbial metabolisms and the redox evolution of the oceans. Archean sedimentary rocks display greater variability in iron… Expand

Molybdenum isotope fractionation and speciation in a euxinic lake—Testing ways to discern isotope fractionation processes in a sulfidic setting
Abstract The molybdenum (Mo) isotope composition in euxinic shales has been used as a proxy for the global distribution of anoxic conditions in ancient oceans, and since more recently also as a proxy… Expand
Thallium-isotopic compositions of euxinic sediments as a proxy for global manganese-oxide burial
Abstract Thallium (Tl) isotopes are a new and potentially powerful paleoredox proxy that may track bottom water oxygen conditions based on the global burial flux of manganese oxides. Thallium has a… Expand

Iron stable isotopes: beyond biosignatures
Abstract The stable isotope geochemistry of Fe has attracted intense interest in the past five years. This interest was originally motivated by the possible use of Fe isotopes in biosignature… Expand
Iron Isotope Constraints on the Archean and Paleoproterozoic Ocean Redox State
TLDR
Variable and negative iron isotope values in pyrites older than about 2.3 Ga suggest that an iron-rich global ocean was strongly affected by the deposition of iron oxides in a redox stratified ocean. Expand

TLDR
