In the What’s On section of this page you can see forthcoming geology talks, field trips and activities organised by the Society Geology Group. All Society members are very welcome to come along to these friendly events, whether you are a beginner or an expert.

If you are interested in learning more about geology then why not join one of our education courses. Our courses are a mixture of field outings and classroom sessions at the Great North Museum: Hancock. For more details, click here.

The Society also owns a fantastic collection of rocks, minerals and fossils as part of its collections in the Great North Museum: Hancock. As well as visiting the museum you can explore some of this collection online, click here.

The Geology Group is led by Derek Teasdale. If you would like to get more involved and help us to plan, organise or run a lecture or field trip for Society members then we would love to hear from you, please get in contact with us via the Society Office.

Recent Activities:


In August 2014 Derek Teasdale led an examination of the building stones used around the north of Newcastle city centre. We were struck by the somewhat dilapidated appearance of parts of the limestone fascia of the Newcastle Civic Centre – just prior to the council announcing a major refurbishment programme for the building!

Our 2015 season began in June with a well-attended trip to the Claxheugh Rock area of Sunderland. Michael Mawson showed us superb outcrops of the Yellow Sands and the Magnesian Limestone (now called the Zechstein Group). The day ended on a real high at a riverside exposure of the top Carboniferous / base Permian unconformity. In early July, the ever entertaining Paul Williams took us to Haltwhistle Burn in the summer heat. The relaxed feeling of the day, allowed us to explore Paul’s encyclopaedic knowledge of geology. Two weeks later, a highly appreciative group were in the cool and calm of the Society’s archives where June Holmes had created a display of some of the Society’s treasures, and which was met with many an oohh! and aahh! Our final trip of the season was to Beadnell and Bamburgh. Karl Egeland-Eriksen led a very well thought out trip, with an excellent mixture Carboniferous Upper and Middle Limestone group geology and exposures of the Beadnell Dyke and Whin Sill. Karl also showed us where to find ropey flow structures on the Whin Sill outcrop north of Bamburgh, which was a great pleasure to those of us who had read about them, but couldn’t find them on the beach.

We are very grateful to the leaders who gave their time and expertise and enabled us to learn a great deal and have fun in an informal and supportive environment – who could ask for more!
