Join Stuart Jones for the second in our series of online talks from external speakers exploring different aspects of geology.
About this Event
The Permian and Triassic sedimentary succession of Cumbria occupy a series of fault-bounded basins formed in response to regional east–west directed crustal extension during the formation and eventual breakup of the supercontinent known as Pangaea. These sandstone-dominated successions include a predominance of red coloured sandstones including Permian Brockram Breccia, Penrith sandstone and the Triassic St Bees Sandstone and Kirklinton sandstone. In this presentation the reason for the presence of so many red coloured sandstones will be explored, through detailed field sedimentology and the latest petrographic techniques (e.g. SEM-EDS and QEMSCAN). This will be linked to our understanding of the ancient depositional environments, palaeogeography and recognition of these sandstones as excellent building stones dating back to Prehistoric times e.g. Early Bronze age ‘Long Meg and her Daughers” and still widely used as a vernacular building stone today.
The session will be live and held online via Zoom. We will email you with the Zoom joining details by 3pm the day before the event.
