We will examine a range of rocks within the Hebridean Terrane, ranging from Archaean gneisses of the Lewisian Complex and the overlying Proterozoic sedimentary rocks of the Torridonian Supergroup through to glacial deposits of the Pleistocene epoch.

We will be looking at several sites around the park, including the area around the now disused barite mine, and considering aspects of our industrial geological heritage.

We will continue our exploration of Glen Lednock and will visit the Comrie pluton to examine the igneous rocks themselves and their contact relations with the country rocks.

We will examine Devonian volcanic and sedimentary rocks (perhaps including the source of the Stone of Destiny) and look at a variety of building stones in Perth City.

The opencast coal site at Spireslack in East Ayrshire delivers a unique and stunning geological exposure of the Carboniferous. BGS is working closely with the Scottish Mines Restoration Trust to find ways of restoring the site to deliver a unique, natural rock laboratory for industry and university training and research.

This tour will take you behind the scenes of extremely rare isotope metrology at SUERC to illustrate the complexity and effort involved in making precise and accurate measurement of isotopes in minerals and rocks.

Beecraigs visitor centre (dyke and Carboniferous Limestone); Cairnpapple Hill and the Knock (lavas, sill, limestone and mineralization) via Witch Craig geology wall; Petershill Reserve (fossiliferous reef limestone); East Kirkton quarry (time permitting) (oil shales and limestones).

Devonian lavas and sedimentary rocks; Highland Border Complex (with superb pillow lavas); Highland Boundary Fault; ORS/Dalradian unconformity; Dalradian structure and metamorphism; Caledonian and post-Caledonian granites, gabbros, migmatites, dykes and breccia pipes.

1800 Ma gneiss, Precambrian metasediments and fossil stromatolites, the famous Port Askaig Tillite (possible "Snowball Earth"?), low grade metamorphic Dalradian rocks retaining original sedimentary structures, reactivated and reversed extensional faults, substantial mineralisation, 60 Ma igneous intrusions (opening of the Atlantic Ocean) and a large selection of Quaternary Ice Age features.
