The Geological Society of London (1807) is the UK national society for geoscience. It is a learned and professional body, and a registered charity (No. 210161). It exists to promote the geosciences and the professional interests of UK geoscientists.
The Society has over 9000 members and is the largest national geoscience society in Europe.
