Es bildete sich gegen Ende der kaledonischen Orogenese, die mit der Kollision zwischen den tektonischen Platten von Laurentia und Baltikum am Ende des Silur verbunden war und sich bis ins frühe Devon fortsetzte (wahrscheinlich Altersgruppe 430–390 Ma (Millionen Jahre)).

On the Northern Highlands side of the fault the zones of shattering extend up to about 1 km beyond the crush-zone. In the Highlands, earthquakes are linked to seismic activity along the ancient Great Glen Fault, a zone of fractures in two blocks of rock that are moving slowly in opposite directions. It formed towards the end of the Caledonian orogeny (mountain building) associated with the collision between the Laurentia and Baltic tectonic plates at the end of the Silurian period continuing into the Early Devonian (likely age range - 430-390 Ma (million years)). The Great Glen, a major geological fault line cutting diagonally across the Highlands from Fort William to Inverness, is the defining geographic feature of the north of Scotland. Information and resources for teachers and students from Published: 21 June 1974; Great Glen Fault. If this discrepancy is correct, lines of major transcurrent dislocation have yet to be identified either in the North Atlantic continental shelves and margins or in eastern North America, and the Great Glen fault was not the main locus of offset between Britain and North America. Loch Ness was formed after that by glaciers. It formed towards the end of the Caledonian orogeny associated with the collision between the Laurentia and Baltic tectonic plates at the end of the Silurian continuing into the Early Devonian (likely age range 430–390 Ma (million years)).

Geologists will tell you that the Great Glen divides the North of Scotland along a line from Fort William to Inverness and that the fault is a very old feature and has been active since Mid Devonian times (c.400 million years ago). The fault is actually much longer, and over 400 million years old. Aligned northeast to southwest, the Great Glen Fault extends further southwest in a straight line through Loch Linnhe and the Firth of Lorne, and then on into northwestern Ireland, directly through Lough Swilly, Donegal Bay and Clew Bay as the Leannan Fault.

The Great Glen Fault is a long strike-slip fault that runs through its namesake, the Great Glen, in Scotland. „Großes Tal“ von schottisch-gälisch gleann mòr), auch Glen More genannt, ist eine tektonische Verwerfung (Great Glen Fault), die mitten durch Schottland verläuft und das schottische Hochland in die Grampian Mountains und die Northwest Highlands unterteilt. The Great Fault. A zone of shattered rock along the length of the fault is prone to erosion and this has given rise to the development of the most extensive valley in Scotland, the Great Glen ( Glen Mor ). Structured data. It consists of a zone of crushed rock (now represented mainly by indurated cataclasite) up to 0.5 km wide, flanked by zones of minor faulting and shattering. It was one of the first such structures to gain wide acceptance and in the years before plate tectonics was established, was important evidence for large-scale lateral earth movements. Aligned northeast to southwest, the Great Glen Fault extends further southwest in a straight line through Loch Linnhe and the Firth of Lorne, and then on into northwestern Ireland, directly through Lough Swilly, Donegal Bay and Clew Bay as the Leannan Fault. The Leannan fault is directly in line with the Great Glen fault and the possibility that it is a continuation of this structure is discussed. The Geological Society offers grades of membership for every stage of your career, from student to retirement. The Great Glen Fault has a long movement history. It originated towards the end of the Caledonian Orogeny (around 430-390 million years ago), and cuts diagonally across the Highlands from Fort William to Inverness. The fault is mostly inactive today, but occasional moderate tremors have been recorded over the past 150 years which has meant that seismic buffers are built into the Kessock Bridge carrying the A9 out of Inverness.
