His 1864 paper On the Physical Cause of the Changes of Climate during Glacial Epochs led to a position in the Edinburgh office of the Geological Survey of Scotland, as keeper of maps and correspondence, where Sir Archibald Geikie, encouraged his research. He was eventually to become a Fellow of the Royal Society. [65]
The geology of the Highlands is complex. Along the western coastal margin it is characterised by Lewisian gneiss, the oldest rock in Scotland. Liathach, Beinn Alligin, Suilven, Cùl Mòr, Cùl Beag, and Quinag are just some of the impressive rock islands of the significantly younger rich brown-coloured Torridonian sandstone which rests on the ...
Awarded UNESCO geopark status in 2004, [1] it was Scotland's first geopark, [2] featuring some of the oldest rocks in Europe, around 3,000 million years old. [3] [4] The park contains many notable geological features, such as the Moine Thrust Belt and Smoo Cave and covers an area of around 2,000 square kilometres (770 sq mi). [1]

Peach and Horne continued their work and published The Geological Structure of the North-West Highlands of Scotland in 1907 with Geikie, in his retirement, making the final editing. [83] Their research was into one of the most geologically complex regions of Britain, [note 11] and they introduced the term "Moine Thrust".
Sketch geological map of Orkney. The geology of the Orkney islands in northern Scotland is dominated by the Devonian Old Red Sandstone (ORS). In the southwestern part of Mainland, this sequence can be seen to rest unconformably on a Moinian type metamorphic basement.
Geological map of the Hebridean terrane showing distribution of rocks of the Lewisian complex Undeformed Scourie dyke cutting Lewisian Gneiss, about 1.6 km west of Scourie Scourie dykes (now foliated amphibolites) cutting grey gneiss of the Scourie complex, both deformed during the Laxfordian tectonic event and cut by later (unfoliated) granite veins - road cutting on the A838 just north of ...
Scotland's main mountainous region can be broadly further split into the Northwest Highlands, the Grampian Mountains and the islands off the west coast. As the name implies, the NW Highlands begin at the suture north and west of the Great Glen and include exactly 100 of the 282 Munros.
