Rosneath and Loch Long

Leader: Dr Iain Allison

This excursion deals with the Upper Dalradian rocks immediately north of the Highland Boundary Fault where the grade of metamorphism is low and remnants of the rocks’ sedimentary origins can be discerned. The trip will concentrate on the tectonic minor structures which are well displayed and show how they can be used to elucidate the regional structure. The rocks occur within the Tay Nappe, one of the largest structures in the UK, and are affected by the downbend fold near the Highland Boundary Fault, again a large structure which can be traced along the fault to the north-east. We shall see the progressive overprinting of earlier structures by those formed later and we will consider the processes operating at the grain level which allow the folds and cleavages to develop.

£15 deposit. This is set at a level to recover the anticipated costs of the trip. In addition, please be aware that any balance of costs will be recovered by a small surcharge on the day of the excursion.

Leaving Gregory Building at 9:00, travelling by coach
