Excursion by Paul Smith and Robert Raine
Excursion 1A from: Goodenough, Kathryn M. and Krabbendam, Maartin (Editors) A geological excursion guide to the North-west Highlands of Scotland. Edinburgh : Edinburgh Geological Society in association with NMS Enterprises Limited, 2011.
Purpose | To examine the stratigraphy and sedimentology of the foreland succession and the lower part of the Achmore Duplex, and to study the structural archi-tecture of the duplex. A good general introduction for any party visiting the North-west Highlands. |
Aspects covered | Clastic and carbonate sedimentology, Precambrian-Lower Cambrian stratigraphy, structural geology of duplexes. |
Maps | OS: 1:50,000 Landranger sheet 15 Loch Assynt; 1:25,000 Explorer sheet 442 Assynt and Lochinver. BGS: 1:50,000 special sheet, Assynt district. |
Terrain | Roadside outcrops on the first part of the itinerary; rough but low moorland and stream sections for the second half of the excursion. No part of the excursion is more than 500m from the road. There are a number of lay-bys at which it is possible to park, but the roadside part of the excursion is most easily accomplished by walking along the road, paying due attention to the traffic. |
Time | The two halves of the trip divide conveniently into separate half-day excursions or a single full day. |
Access | There are no access con-straints for this excursion, although care should be taken at roadside stops. Please note that this is a very popular excursion, and that the outcrops should not be hammered. |
There are two parts to this excursion:
Excursion 1A: The foreland succession of the Loch Assynt roadside
Excursion 1B: The stratigraphy and structure of the Achmore Duplex and adjacent foreland
