Geowalks: Evidence of Snowball Earth, with David Webster

18 January @ 7:00 pm - 8:00 pm

The ‘Snowball Earth’ deposits of Islay and the Garvellachs are one of the ‘51 Best Places to see Scotland’s Geology’. Together the islands record a thick, well-exposed, and complete section through a major glacial episode which is correlated with the global ‘Sturtian’ event that occurred some 720 million years ago. The Garvellachs section is proposed as a ‘golden spike’ to mark the definitive base of the Cryogenian Period of the Precambrian; and in northern Islay there are several candidates for a cap-carbonate which mark the termination of the glacial cycle.

Organised by Geowalks as part of a series of introductory online talks on Scottish geology – www.geowalks.co.uk/geology-talks/
