1912 Geological map of the south east Highlands, Scotland, showing the first observations of a regular sequence of changes in mineralogy within metamorphic rocks by George Barrow (1853–1932) Ignored for 20 years, Barrow's zones were to unlock the understanding of regional metamorphism, and, later, the identification of ancient subduction zones.

Welcome to the
History of Geology Group
HOGG

HOGG  (The History of Geology Group) 

…….exists to encourage and share interest in knowledge and study of the history of geology, encompassing the ideas, events and personalities that have shaped the way in which geology is understood and practised today.

Membership is open to anyone interested in how geological knowledge has developed and has been represented e.g. through geological maps or illustrations. 

HOGG is a diverse and inclusive group. Our members are drawn from a wide range of backgrounds – there is no requirement to have geological credentials. 

Amongst HOGG members are historians, artists, medics, teachers, linguists, archivists, amateurs and professionals.

We encourage interest from young people.  

HOGG members enjoy a programme of regular activities:   online talks,  field meetings, conferences and symposia – they receive the acclaimed HOGG magazine GeoHistories , plus regular updates via a HOGG Bulletin, and benefit from a network of knowledgeable enthusiasts.
