John Faithfull ππͺπΊπ΄σ §σ ’σ ³σ £σ ΄σ Ώπ§‘βπ»βπΏThe Garvellach islands, just south of Mull, have fabulous rocks preserving detailed records of repeated Neoproterozoic "snowball Earth" glaciations. But the exact age, and correlation with similar rocks elsewhere, has been controversial. New #OpenAccess paper shows that the sequence seems entirely Sturtian (older than 662 million years) + may be the most complete Sturtian section preserved on Earth.π€ππhttps://www.lyellcollection.org/doi/full/10.1144/jgs2024-029 #Cryogenian #SnowballEarth #Geology @Ruth_Mottram @TatianaIlyina

As I recall, a complete Port Askaig sequence can also be found in the many Islay distilleries β¦

@BashStKid @Ruth_Mottram @TatianaIlyina the Islay sequence is not quite as complete as the Garvellachs, but there may be other compensations π₯ππ. I have never been to Islay, or the Garvellachs. I need to do something about this!
Bob Downie@FaithfullJohn @BashStKid @Ruth_Mottram @TatianaIlyina There is a Glasgow Geological Society trip to the Garvellachs next May so if you are a member and act nippy......
I think I have a place.
Ruth MottramYou should definitely go to the Garvellachs! They're incredibly beautiful we had a brilliant sea kayak trip there about 20 years ago. The archaeology is also fascinating.
