The cycling of iron (Fe) is often closely linked with that of carbon, nitrogen, phosphorus and
manganese. Therefore, alterations in the Fe cycle may be indicative of concurrent overall …

Atmospheric particulate matter (PM) has a significant impact on both the natural environment
and human health. Iron is one of the most abundant elements in the earth's crust, playing an …

Magnesium isotopic compositions of a profile through saprolites developed on a diabase
dike from South Carolina have been measured in order to study the behavior of Mg isotopes …

High-temperature isotopic variations documented in natural materials span a narrow range
and call for precise and accurate isotopic analyses. Precisions better than~ 0.03‰(95 …

Iron compounds in soil are multifunctional, providing physical structure, ion sorption sites,
catalytic reaction-centers, and a sink for respiratory electrons. Basaltic soils contain large …

Iron and copper isotopes are useful tools to track redox transformation and biogeochemical
cycling in natural environment. To study the relationships of stable Fe and Cu isotopic …

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 …

Pedogenic thresholds occur where soil properties change abruptly and/or nonlinearly with a
small increment in environmental forcing; soil process domains are the regions between …

When rock is converted to weathering products, the involved processes can be fingerprinted
using the stable isotope ratios of metals (for example Li, Mg, Ca, Fe, Sr) and metalloids (B …

Komatiites from Alexo, Canada, are well preserved and represent high-degree partial
mantle melts (∼ 50%). They are thus well suited for investigating the Mg and Fe isotopic …
