Scotland at 78,772 square kilometres (30,410 sq mi),[2] is second largest, accounting for about a third of the area of the UK… Journal of the Geological Society, London 170, 603 –14. Reprint 2007. Rare layers of volcanic rock also occur in the Dalradian rocks. The Grampian Mountains, Am Monadh in Gaelic, are one of the three major mountain ranges in Scotland, ranging from the southwest to the northwest between the Highland Boundary Fault and the Great Glen. All of these igneous rocks constitute the Caledonian Igneous Suite. part of the Grampian mountains - a component of the Caledonian fold mountain chain which stretches from northern Norway through Shetland, then on via Scotland to Ireland and Wales. The Moray–Buchan coastal area represents the southern margin of the large, continental Orcadian Basin. Thick dykes of quartz-dolerite, the northern edge of a swarm which is centred in the Midland Valley, occur in the Southern Highlands from Loch Awe to Aberdeenshire and are of late Carboniferous to earliest Permian age. The late Palaeozoic is also represented by two suites of minor intrusions. It is evident that the post-orogenic plutonic rocks were intruded during a phase of very active uplift and erosion so that by early Devonian time the area of the Grampian Highlands was one of considerable relief in which the full range of Dalradian metasedimentary rocks and Caledonian igneous rocks was exposed at the surface. Around Oban there is also an extensive development of andesitic lavas within the Lower Old Red Sandstone. Ben Nevis is the UK's highest peak and is found in the Grampian Mountains. The rocks of the Grampian Highlands are bounded by the: About 800 million years ago, immense forces broke apart an ancient continent, opening up the Iapetus Ocean. Whether you're a wine taster, outdoor explorer or food lover, the Grampians has an adventure waiting for you. These are probably the result of the high local heat flow which also resulted in the intrusion of large volumes of basic and acid plutonic igneous rocks there. The land between the Great Glen Fault to the northwest and the Highland Boundary Fault to the southeast is known to geologists as the Grampian Terrane. British regional geology: the Grampian Highlands. Most of this deposition remains offshore but on the Moray coast around Lossiemouth there are small outcrops of Permo-Triassic and Jurassic rocks, mainly continental facies sandstones which have yielded a rich reptile fauna. Apart from some Carboniferous rocks along the Highland Border and a small area of Permian to Jurassic rocks near Lossiemouth, the only significant post-Devonian deposits are the widespread Quaternary glacial deposits. Late Precambrian metamorphosed sedimentary rocks of the Dalradian Supergroup, and a wide variety of igneous rocks intruded into them, form most of the Grampian Highlands. The Dalradian rocks, which formed from this sediment, include: Later, the Dalradian rocks were heated and compressed by the continental collisions that brought together Scotland’s foundations. The Rhinns rocks are overlain by the low-grade Colonsay Group metasedimentary rocks, whose correlation across a splay of the Great Glen Fault with the rocks on the mainland of Scotland is still uncertain, although a late Precambrian age for the Colonsay Group seems most likely. The rocks are mostly clastic— scree breccias, conglomerates, sandstones and siltstones. As in Norway, the coastline is deeply penetrated by fjords, and the steep mountain sides, many rising vertically for 1000–2000 m out of the … The name ‘Caledonides’ was given by E Suess to this mountain belt which extends from the eastern seaboard of North America to Scandinavia and Greenland; in Britian and Ireland its width is from north-west Scotland to central Wales. Discover grand and rugged mountain ranges, spectacular wildflower displays, a wide range of outdoor recreational opportunities, and a wealth of Aboriginal rock art sites in the Grampians National Park. Stable shallow-marine deposition followed, resulting in deposition of quartzite-shale-limestone sequences of the Appin Group, in which some stratigraphical units maintain a constancy of character across the Grampians from north-east to south-west, and even into Ireland. England Lyell was born at Kinnordy, the stately family home at the foot of the Grampian Mountains in eastern Scotland. The older nappes carry the youngest sedimentary rocks that were deposited further away downstream from the Grenville mountains. The nappe folds were deformed by subsequent folds and thrusts of generally similar trend and form, and by a series of later, generally upright folds which trend in a variety of directions; they include a major monoform or downbend along the Highland Border. England's Lake District is, as its name suggests, known for its many scenic lakes. Late Palaeozoic and Mesozoic rocks are now found in large basins of deposition to the north and south of the Grampians and in small internal basins, but may formerly have extended over much of the region. The Moine Supergroup, following the Grampian and Scandian events, was re-arranged into a major series of nappes. 70 The Geology of Ireland of this lineament is commonly a fault, as is particularly evident in the Clew Bay region (Fig. Tackling raptor persecution, poaching and hare coursing will be top priorities covering all of Scotland. The Grampian Highlands region covers a large area and understanding its complex geology calls for a wide variety of geological expertise. This downbend was probably associated with uplift prior to the obduction on to the margin of the Highlands of the Cambro-Ordovician rocks and ophiolite suite which together constitute the Highland Border Complex and which are preserved as a number of separate slivers within the Highland Boundary Fault Zone.
