Geology and resources of SW England, Cornwall and the Isles of Scilly
SW England is a superb natural laboratory that, in common with basement massifs across western and central Europe, records the development and destruction of the Variscan mountain belt during the formation of Pangea. My research addresses regional geological evolution and the associated fundamental geological processes, i.e. Variscan / post-Variscan tectonics and its influence on, and interactions between, structural geology, sedimentation, magmatism, mineralisation and landscape development (further details via right-hand sidebar).
The geological evolution of SW England resulted in an outstanding endowment of natural resources that underpinned a globally significant mining industry for much of the 18th-20th centuries, and world-leading research on 'Hot Dry Rock' geothermal energy in the 1970s-1980s. Kaolinite has been produced from altered granites for almost three centuries and is a major UK industrial mineral export. Since the mid-2000s there has been a resurgence of exploration interest in the UK's most prospective region for the metals tungsten (W), tin (Sn), copper (Cu), lithium (Li) and for deep geothermal energy. The first 'new' metal mine worked the strategically important Hemerdon W-Sn deposit in Devon between 2015-18 and was reposible for the UK becoming the fourth biggest global tungsten producer in 2017-18. In 2019, the deepest onshore borehole in the UK (5057 m TVD / 5275 MD) was completed as part of the United Downs Deep Geothermal Power Project and Eden Geothermal Limited completed their first deep geothermal well in late 2021 that is, just, the longest in the UK (4867 m TVD / 5277 MD). These are nationally and internationally significant projects.
The applied research that I undertake addresses how fundamental geological processes and regional geological evolution contribute, both positively and negatively, to these resources and their exploration and production (figure below). I've been involved in colloborative research and knowledge transfer with most of the resource companies who have operated in SW England and my NERC-funded research contributes to the ExeterCleanGrowth theme.

Collaboration and Knowledge Transfer
The knowledge and understanding associated with a long period of geological research in the region is underpinned by, and further contributes to, collaborative and contract minerals industry research / consultancy and knowledge transfer. Present and past collaborators include: British Geological Survey, Cornish Lithium, Cornish Tin, Cornwall Council, Cornwall Resources, CSM Associates, David Roche Geo Consulting, Eden Geothermal, EGS Energy, Elcon Western, GeoScience, Geothermal Engineering, Helford Geoscience, Imerys Minerals, JSC Altynamas, Menteri Besar Incorporated, Satellite Applications Catapult, Treliver Minerals, Tungsten West, Western United Mines and Wolf Minerals on projects that typically involve regional geology, structural geology, granites, mineralisation and/or mineralogical characterisation and their mineral / geothermal resource implications. The National Trust and The University of Plymouth have been collaborators on coastal landsliding projects.
