Professional biography

Dr Clare Warren

I'm a Senior Lecturer in the School of Environment, Earth and Ecosystem Sciences.   My research centres around the evolution of mountain belts that form when ocean basins close and continents collide. Much of my recent work has concentrated on determining how and when deeply buried rocks record the timing of their burial and exhumation, as well as on determining burial, transformation and exhumation processes and mechanisms.   I work closely with the Open University Ar/Ar  and  Himalayan-Tibet Research Groups and the NERC Isotope Geoscience Laboratories Geochronology and Tracer Facility.

I am always interested in hearing from potential students and postdocs who want to come and work in metamorphic, geochronological and tectonics research at the Open University.   Please send me an email.


Research interests

The geochronological evolution of metamorphic rocks, specifically using Ar/Ar (mica) and U-Pb (monazite, rutile, titanite, zircon).

Metamorphic pressure-temperature-time path modelling.

Diffusion modelling, in particular the diffusion of species important to geochronology (e.g. Ar in muscovite, Pb in rutile) and thermobarometry (e.g. Zr in rutile).

Modelling geodynamic processes, and specifically the formation and exhumation of high pressure rocks in continental collision zones.




Developing trace element fingerprinting techniques to constrain rates and timescales of tectonic processes

Diffusion processes in minerals important for geochronology and thermobarometry

Developing ways of using noble gases as tracers of tectonic processes and fluid flow

Burial and exhumation processes of the Western Gneiss Region, Norway

The geology and tectonics of the eastern Himalaya

Impact and engagement

The 2013 CEPSAR Christmas lectures are now featured on the National Co-ordinating Centre for Public Engagement Case Studies pages here.

Between Jan-March 2015 I helped to run a series of end-user engagement and media training workshops with Richard Holliman, funded by a NERC Innovation grant to the CENTA doctoral training partnership.

CENTA is a geographically and scientifically coherent consortium offering a wide range of excellent NERC science embedded in a vibrant multidisciplinary environment. The Universities (Birmingham, Leicester, Loughborough, Open and Warwick) and Institutes (British Geological Survey and Centre for Ecology and Hydrology) have a strong track record of producing PhD graduates fit for further research or other relevant employment. We will advance PhD training significantly by offering broad and holistic educational opportunities in the environmental sciences, including innovative approaches to cohort training, supported by the Open University’s Virtual Research Environment learning platform. Where we offer leading national capability, we will offer training to other NERC consortia in addition to CENTA students. We are match-funding this bid for 20 studentships annually.CENTA defines its four areas of science excellence as follows: 1) Anthropogenic impacts and environmental sustainability. 2) Evolution of organisms and ecosystems. 3) Dynamic Earth. 4) Organisms.
