The largest Fe isotope fractionations occur during redox changes, as well as differences in
bonding, but these are expressed only in natural environments in which significant …

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 …

Benthic iron fluxes from sites along the Oregon–California continental shelf determined
using in situ benthic chambers, range from less than 10μmolm− 2d− 1 to values in excess …

We present the first comprehensive set of stable Cr isotope data for the major igneous
silicate Earth reservoirs, Cr (III)-rich ores and minerals, and hydrothermal chromates. These …

Combined Fe, C, and O isotope measurements of~ 2.5 Ga banded iron formation (BIF)
carbonates from the Kuruman Iron Formation and underlying BIF and platform Ca–Mg …

Abstract The study of Fe, Zn and Cd stable isotopes (δ 56 Fe, δ 66 Zn and δ 114 Cd) in
seawater is a new field, which promises to elucidate the marine cycling of these bioactive …

Microbial dissimilatory iron reduction (DIR) is widespread in anaerobic sediments and is a
key producer of aqueous Fe (II) in suboxic sediments that contain reactive ferric oxides …

Fe isotopes can provide new insight into redox-dependent biogeochemical processes.
Precambrian iron formations (IF) are deserving targets for Fe isotope studies because they …

Enhanced analytical capabilities and separation techniques, improved detection limits, and
accessibility of instrumentation have led to massive strides in the use of isotopes to assess …

We conducted a geochemical and petrographic study of the 1.89 billion year old Gunflint
and Biwabik iron formations, with the goal of determining the importance of microbial iron …
