Carboniferous fluvial, deltaic and shallow marine strata pierced by Carboniferous vents (diatremes) and the interplay between volcanism and sedimentation

Ordovician volcanics, with evidence for giant ash-flow eruptions, and large-scale Caledonian folding, all set in Snowdonia’s wonderful glacier-carved mountain scenery.

Carboniferous, Permo-Carboniferous and Palaeogene igneous rocks, columnar-jointed sandstone, Dalradian slates, schists and grits, along with the Highland Boundary Fault and Highland Border Complex.

Devonian sedimentary rocks and igneous structures, Clyde Plateau Lavas, glacial erratics, beach pebbles and post-glacial landscape features

Carboniferous limestones, fossils, lavas and tuffs

A visit to the Museum of Lead Mining with a tour underground to the eighteenth century Lochnell Mine. We are also going out to pan for gold in the local streams.

Exploring the igneous complexes that were formed in the final stages of the closure of the Iapetus Ocean in the Silurian period.

Important aspects of the early Ordovician Ballantrae Ophiolite Complex, late Ordovician and early Silurian greywacke and conglomerate; late Ordovician reef limestone and Caledonian folding; and possibly the pillow lavas at Downan Point.

A joint excursion with the Edinburgh Geological Society to examine the rocks around the Highland Boundary Fault and gain some understanding of why there has been considerable controversy over the geological history of this zone

Sandstone and other sedimentary rocks laid down in river deltas, swamps and sea in the Carboniferous period and evidence of the Quaternary glaciation
