The Rocks and Landscapes of Duns, Scottish Borders

Alison Tymon
West Yorkshire Geology Trust

Duns was the county town of the historic county of Berwickshire, so has a glorious history and some pleasant buildings in the centre of the town. The surrounding countryside has sedimentary and igneous rocks, ranging from Silurian greywackes and Old Red Sandstones to Carboniferous igneous and sedimentary rocks. Nearby is a potential golden spike locality between the Devonian and the Carboniferous periods, as well as many towers and castles positioned on top of volcanic plugs.

This talk will be delivered via Microsoft Teams. Joining instructions will be circulated to members nearer the date. Non-members are welcome to attend and should email the Secretary at lga.sec@btinternet.com no later than 24 hours before the scheduled start time, to request joining instructions.
