Residential excursions 2024

The Garvellachs; 10 May – 13 May 2024

Leaders: Tony Spencer & David Webster

Field days: Saturday/Sunday/Monday

Geological Background
The Garvellach islands expose a magnificent section of the glacial Neoproterozoic Port Askaig Formation. Although part of the Dalradian, it is relatively undeformed and contains an extraordinary amount of glacial features including spectacular glaciotectonic “rafts” as well as a sequence at the base recording the transitional onset of glaciation at the start of the Cryogenian – which is a prime candidate for a global “golden spike” or GSSP. We will discuss the concept of snowball earth and assess how the succession here fits (or doesn’t) with that model. We will aim to have one day on each of the three main islands in the archipelago.

No of participants: 10 maximum

We expect this excursion to be over-subscribed. If it is, there will be a ballot for the 10 places available. Expressions of interest are invited by email, to the hon. secretary by 5 pm on Friday 15 December. After that we will let people know if they have been successful in gaining a place, create an ordered waiting list of unsuccessful applicants and add any further expressions of interest. We would expect full payment by the end of January.
