SUMMARY:Stoer Group (Torridonian) - Peter Gutteridge
DESCRIPTION:Microbially-mediated carbonates in the Mesoproterozoic Stoer Group; earliest evidence of life in Britain?Carbonates within the Stoer Group\, previously interpreted as abiogenic structures\, are reinterpreted as microbial stromatolites. Stromatolites form by a combination of sediment trapping\, binding and precipitation of carbonates associated with microbial activity. They take the form of mats and domical structures a few tens of cm in size that grew in water a few cm deep around the margins of lakes. Some larger stromatolitic structures\, several tens of metres across\, formed in the deeper parts of lake margins and over the front of coarse-grained deltas as they built out into lakes. These stromatolites are also associated with sedimentary structures that bound the sediment during deposition\, but without carbonate precipitation. These may indicate the present of a range of calcifying and non-calcifying microbial communities during deposition of the Stoer Group. \n\n\n\nPeter Gutteridge – BiographyI first discovered the carbonates within the Stoer Group when I mapped the Stoer Peninsula as an undergraduate at Leeds University. Afterwards\, I did a Ph.D. at Manchester University on Dinantian carbonates in Derbyshire and since then spent my professional career looking at carbonate systems of all ages from all over the world. I am a visiting lecturer at Manchester University\, researching Dinantian carbonates\, carbonate breccia systems\, evaporites and Precambrian carbonates. \n\n\n\nPeter Gutteridge\n\n\n\nThis lecture will be offered in a hybrid format.
