Geochemistry of the Earth system

Research Isotope geochemistry of the Earth system with The Open University. Rare gas laboratory (photo: James Schwanenthal).

Geochemistry has been a major focus of the research carried out at The Open University for nearly 40 years.

Academics and researchers from Earth sciences use cutting-edge geochemical techniques, such as laser ablation (LA) inductively coupled plasma mass spectrometry (ICP-MS) and solution ICP-MS, to study a very diverse range of problems in the Earth and environmental sciences. Our research interests cover present-day and past environmental change; oceanography and palaeoceanography; tectonics and mountain building; volcano dynamics; sedimentology and stratigraphy, ore formation and the evolution of the Earth's mantle and crust. Geochemistry has been central to the major contributions to the international research agendas in these varied fields that have been made by academics and researchers at the OU since the 1970s.

Potential research projects

We encourage enquiries from prospective students on any geochemical, biotic or geochronological aspect of present-day or palaeoenvironmental change. Lists of postgraduate research projects likely to be available for a 2018 start will become available towards the end of 2017.

Please also see further opportunities.
