Research Interests

Christopher Jeans is a self-supported consultant post-doctoral worker, and an affiliated member of the QPG. He is a research earth scientist specialising in the geology, petrology and geochemistry of sedimentary rocks and soils with extensive experience in their application to the needs of Industry and Society. Particularly in problems involving oil and gas exploration and production, the distribution and effects of clay minerals in the natural environment, and the use of forensic soil evidence in murder and other criminal trials. Research interests are the interrelationship between sediments/soils and clay mineralogy/geochemistry with special regard to the Mesozoic rocks of Europe (particularly the Upper Cretaceous Chalk) and New Zealand.


Chris will be awarded the Collins Medal for 2013 by the Mineralogical Society of Great Britain and Ireland. He was already made an Honorary Fellow of the Society in 2011.

'The Collins Medal will be awarded annually to a scientist who, during a long and active career, has made an outstanding contribution to pure or applied aspects of Mineral Sciences and associated studies. Publications, teaching, outreach and other activities leading to the promotion of mineral sciences, in the broadest sense, will be taken into account in making the award. Nominees do not have to be Members of the Mineralogical Society or nationals of Great Britain and Ireland.'
