The Iron Speciation Paleoredox Proxy

About this book

In one form or another, iron speciation has had a long history as a palaeoredox proxy. The technique has been refined considerably over the years, and the most recent scheme is unique in its potential to distinguish three major oceanic redox states – oxygenated, ferruginous and euxinic. This Element covers the theory behind the proxy, methods involved in applying the technique, and potential complications in interpreting Fe speciation data. A series of case studies are also provided, which highlight how more advanced consideration of the data, often in concert with other techniques, can provide unprecedented insight into the redox state of ancient oceans.

Biography

Professor Simon Poulton is Chair of Biogeochemistry and Earth History at the University of Leeds. Originally trained as a geologist, his research focuses on geochemical and biogeochemical processes in modern sediments and waters, with a view to applying this understanding to ancient environments.
