Joint excursion with the Edinburgh Geological Society

The objectives of this excursion are to examine the rocks around the Highland Boundary Fault, which separates the Palaeozoic rocks of the Midland Valley from the late Proterozoic rocks of the Grampian Highlands and cuts across mainland Scotland from Helensburgh to Stonehaven, and to gain some understanding of why there has been considerable controversy over the geological history of this zone.

The units we will examine are:
Devonian: Upper Old Red Sandstone, Lower Old Red Sandstone;
Ordovician: Highland Border Complex, Arrochymore Sandstone, black shale, limestone with serpentinite pebbles, serpentinite;
Proterozoic: Dalradian (Southern Highland Group).

Following the excursion, we will have a bar meal with our EGS colleagues.

Leaving Molema Building at 9:00, returning at 19:00, travelling by coach.

The numbers on this joint excursion are limited to 15 from each society. Therefore early booking is advisable if you wish to make sure of a place.
