Time: 12:00PM - 12:00PM
Type: Excursion

Description

Leader: Dr Brian Bell

Field days: Friday(afternoon)/Saturday/Sunday/Monday(morning)

The island of Raasay comprises a wide range of well-exposed rocks within the Hebridean Terrane, ranging from Archaean gneisses of the Lewisian Complex and the unconformably overlying Proterozoic clastic sedimentary rocks of the so-called Torridonian Supergroup, through to glacial deposits of the Pleistocene epoch. Mesozoic strata include various continental clastic sedimentary rocks, overlain by marine and estuarine deposits of the Lower and Middle Jurassic Period, including the Raasay Ironstone Formation. Palaeogene igneous activity resulted in both intrusive and extrusive units – lavas and granite. Pleistocene glacial activity produced diamictites and erratics, and striae on the harder rocks, while active landslips occur in the south-east of the island. This excursion aims to examine the entire range of rocks, and the industrial archaeology of the Raasay ironstone mine will also be addressed.

More details of the excursion can be found here.

N.B. Accommodation in Raasay is very scarce. Apart from a couple of B&Bs, there is only Raasay House which can accommodate a group of 20 of us in twin rooms, dinner, B&B, at a rate which is a bit more expensive than average. There are no other eating places on the island. Raasay House gets fully booked very rapidly, even a year in advance, and for this reason our provisional booking needs to be confirmed in the very near future. Therefore, if you are at all interested in this special trip, please let the Residential Excursion Secretary, Maggie Donnelly (restrips@gsocg.org) know as soon as possible, and preferably by 28 February 2017, to let us establish whether the trip is indeed viable. Of course, no deposit is required at this stage. Also, please note that the 2017 prices are being held for us.
