... Abstract In 1828, Charles Lyell (1797–1875), Charlotte Murchison (1788–1869) and her husband Roderick Impey Murchison (1792–1871) embarked on a long journey around Europe. The party left Paris in May 1828, travelled through the Massif Central and continued southwards. The geological programme...

... that the granite, emplaced at a depth of 7–14 km, formed in the same extensional tectonic setting as the Tayvallich lavas at 600 Ma. Geochemical and isotope parameters point to a largely crustal source. The intrusion belongs to a swarm of rift-related, A-type granitoids that originally stretched from...

The clast content of these rocks indicates that before widespread Lower Devonian calc-alkaline volcanism, this source terrane included volcanic and hypabyssal igneous rocks that appear to have been associated with a wacke sandstone-dominated sedimentary sequence and a granitic igneous suite...

Newly discovered slices of gneiss occur farther SE, just above the Southern Moine Thrust in Dundonnell River [NH 115 847] and on the southern side of the Dundonnell Culmination [NH 125 877] ( Fig. 2 ). The slices are highly sheared, mylonitic...

We have examined the subsidiary bodies of granitic gneiss lying north (Roberts 1984) and south (A.J.H.) of the area described by Peacock, i.e. between Glen Doe and Glen Affric, and south of the River Moriston. The gneiss possesses...

..., Magnason, who also acted as a servant. On 29 July 1844 Murchison and Lovén left Göteborg. They started out on the high road to Stockholm, but then left that road and crossed two branches of the Göta River on their way to Kungälv and Uddevalla (Fig. 1 ). At Uddevalla, they observed the magnificent raised...

... fold nappe occupies most of Knoydart and is stratigraphically coherent and right-way-up. Within this sequence, the upper unit of the Lower Morar Psammite is barely deformed, preserving trough-cross-bedding and large-scale channels in thick beds. This suggests braided river deposition, similar...
