Wednesday 20 October at 7pm on zoom

Dr Jenny Bennett, Chair of Geology Section, The Devonshire Association. 'Eileen Hendriks, the Rock Lady – Disentangling Devonian Geology in Devon and Cornwall'.

Eileen Lind Hendriks (1887–1978) played a pivotal role in resolving the stratigraphy and structure of Devon and Cornwall, despite difficult family circumstances, the impact on her career of two world wars, financial problems, loneliness and the general apathy of the wider geological community. Although regarded by some as an amateur, perhaps because she was unconnected with any institution, she was treated as the acknowledged authority by the young researchers who started to work in the SW after 1950. She is still remembered and respected for her painstaking work in an area which was apparently barren of fossils, causing the Geological Survey to revise a map and memoir less than 20 years after publication.  The map shows the field area where her meticulous research resolved the Palaeozoic stratigraphy and structure of South-West England.

Mark Vanstone, Director of Studies, Truro School:  Recording earthquakes with a Raspberry Shake (provisional title)









Wednesday 19 January 2022 at 7pm on zoom

Anna Rood, Department of Civil and Environmental Engineering, Imperial College London

Precariously balanced rocks are ancient formations found throughout the world where a slender boulder is balanced in such a way as to be vulnerable to being pushed over by earthquake shaking. These natural balancing acts provide a geological record of seismic shaking of large, rare earthquakes, a record that could drastically improve estimates of future earthquake ground shaking.


Wednesday 16 February 2022 at 7pm on zoom

Professor Murray Gray, Queen Mary University of London.  Geodiversity: redundant term or influential concept? 

This lecture will argue that, contrary to a recent paper that claimed that ”geodiversity” is a redundant term since diversity is implicit in the term “geology”, its introduction has in fact led to several new insights, research outcomes and ideas.








Saturday 22 February following AGM - Annual Address

Professor Karen Hudson-Edwards, Professor of Sustainable Mining, Camborne School of Mines and Environment and Sustainable Institute, University of Exeter.

'Mine Wastes: Canada to Cornwall’, An exploration of the geochemistry, mineralogy, impacts and resource potential of mine wastes occurring from Canada to Cornwall, including updates on new projects in Cornwall, including ‘Legacy Wastes in the Coastal Zone’ and ‘Met4Tech: Developing a Circular Economy Centre on Technology Metals’.
