Some members have expressed interest in a weekend trip, so the following has been arranged:
All day Saturday 29 June 2024 and half-day Sunday 30 June 2024
The Girvan-Ballantrea Complex: Ayrshire coast
Excursion leader: Conn Gillen (University of Edinburgh)
Geology
This will be an opportunity to examine and discuss an ophiolite complex – diverse Ordovician age rocks from the mantle and ocean crust, juxtaposed by faulting. Ophiolites are quite rare. Other ophiolites are in Cornwall and Shetland, so the Girvan-Ballantrae area is definitely our nearest! I expect we’ll examine Silurian strata as well. The origins and histories of these rocks are complicated, but our leader, Conn, is familiar with guiding various groups here and has also offered a pre-trip Zoom briefing. Attendees can get involved with the geological intricacies or take a more introductory approach and admire the excellently exposed rocks that we’ll see, such as pillow lavas, layered chert and so-on.
Background information can be found online. There’s an introduction at: https://www.geologynorth.uk/ballantrae-ophiolite-complex/ More detailed references with geological information will follow with confirmation of your booking.
Practicalities
Attendees need to be ready to start on the Saturday and Sunday mornings. Given the distance from Cumbria this means that arrangements need to be made for Friday night and Saturday night accommodation. (Dates and timing have been governed by low tide conditions). Attendees might want to share transport and accommodation and will need to make their own arrangements. Details of some accommodation suggestions will follow on confirmation of booking. The aim is to have about 15 attendees with individual costs of £20 to cover any possible CGS outlays.
A moderate amount of coastal / foreshore walking will be involved. Stout footwear and weather gear will be needed, as for most of our field excursions. Conn will provide more guidance on topics such as fitness, walking distances, parking / meeting spots, loo stops, potential lunch stops, etc in due course. Attendees will need to use their own vehicles (hopefully shared) to get to start points.
At present there’s no fixed plan for meeting up socially on the Friday or Saturday evenings – this might be fun and is something that can be considered nearer the time (or on the spot).
The excursion is expected to end around lunchtime on Sunday 30 June. Attendees may wish to use the afternoon for more exploration of the Ayrshire coast (seal spotting?!) or for their return trip, or they could extend their stay of course.
