David Webster has been asked to make this presentation by the Open University Geological Society and they are happy for others to join in. This excursion will be a little more technical than David’s previous Islay field trips. It will look at the Rhinns Complex deformation history and its enigmatic contact with the overlying Colonsay Group. Do the newly-discovered conglomerate exposures show us the very base of the Dalradian? If so, how old is it? How many deformations were there? Is the Kilchiaran Shear zone really folded?
The event will take place during the normal Gelogical Society of Glasgow lecture slot – i.e. the second Thursday of the month at 7:30 pm – and will be held as a Zoom meeting. Society members for whom we have email addresses have been sent instructions on how to join the meeting. If you are a member but did not receive an email, or a non-member who would like to join the meeting, please email the society’s meetings secretary to request the instructions.
