Dr Mike Fowler
Reader in Geochemistry
I am a geochemist with 30 years teaching experience. I have taught most flavours of geochemistry over the years, from Earth evolution through petrological applications, simple organic geochemistry, environmental and forensic geochemistry, ore genesis and exploration geochemistry, biogeochemical cycles, to both stable and radiogenic isotope geochemistry. I have particular expertise in elemental and stable isotope analysis of silicate rocks and minerals, but also waters, soils, dusts, and other environmental matrices. I have been Course Leader for Geology and for Environmental Science.
I studied geology and mineral chemistry at the Universities of Bristol and Birmingham, and completed my PhD and an 1851 Research Fellowship at Imperial College. I then worked for the British Geological Survey in its regional geochemistry group and at the NERC Isotope Geology Centre, before teaching geochemistry to geologists at Oxford Brookes for 13 years. From Oxford I moved briefly to the University of Gloucestershire, but have been very happy at Portsmouth since 2006. My main research interests have been in granite petrogenesis and the environmental geochemistry of metals, and more recently in chemical methods for source attribution of industrial fugitive dusts, and environmental mineralogy.
The evolution of continents and the mantle input to granites (often severely underestimated, in my opinion): sources and fractionation mechanisms of high Ba-Sr late orogenic granites, notably those of the British Caledonian province. Comparisons with sanukitoids and implications for Archaean crustal evolution.
Dusty forensics: source apportionment of industrial fugitive dusts. Metals chemistry of directional dust samples and development of environmental forensic methods that allow problem dusts to be traced to source. Consultancy and knowledge transfer applications.
Environmental geochemistry and mineralogy: toxic metals and As release during minespoil degradation, dispersion into the environment via waters and dusts, bioaccessibility, SW England case studies. Respirable crystalline silica (RCS) and fibrous zeolites (e.g. erionite) related to quarrying activity.
