Wednesday 21 July at 7pm on zoom (rescheduled from January)

The Ice Age in Cornwall: new perspectives on old problems. Professor James Scourse, Centre for Geography and Environmental Science, University of Exeter (Penryn).

The recently completed 6-year BRITICE-CHRONO NERC Large Grant has reconstructed in great detail the Last British-Irish Ice Sheet. Highlights in our region include new extensive offshore ice limits, very tight constraints on the timing and extent of the glaciation on Scilly but brought into sharper focus some longstanding problems, such as where was the ice limit offshore north Cornwall, or was north Cornwall glaciated after all?

Field Trip - Sunday 25 July from 2pmQuaternary Geology on the Lizard to follow James Scourse’s RGSC lectureLowland Point (raised beach and loess) and Croft Pascoe, Holocene vegetational and landscape evolution to discuss the origins of the Cornish heath.   Leaders James Scourse and Geoff Garbett.  Families welcome but all under 16's must have an accompanying adult. There will be a walk of about 1 km to Lowland point. The fieldtrip is free for members but we ask £5 per household cash payment for non-members (refunded on joining the RGSC which is just £15 per year).  If you would like to attend, please email your name(s) and address, telephone number, and the telephone number for an emergency contact to Beatrice Kerno ( You will then receive the joining instructions and further information.

Wednesday 20 October at 7pm on zoom

Mining and Miners of Newton St Cyres - Brian Please. Brian is local historian who lives in Newton St Cyres, and is descended from families from this part of Devon.  He is member of the Newton St Cyres History Group, and discovered the remains of manganese mining in a field next to his home. It can be claimed that, together, Upton Pyne, Newton St Cyres had the first commercially successful manganese mines in the world! The talk explores those early mining ventures, how and why it was done, and who did it.



Wednesday 17 November at 7pm at Truro School if possible

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.
