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.
Scotland - and The Great Glen - lie on the Great Glen fault. A fault is where two tectonic plates meet. The other half of this one is in Canada! CONNOR: So Scotland and Canada were once...
In the middle of the 19th century, geologists identified the Great Glen as the location of an ancient fault line, detailing a normal sense of displacement of at least 1000 m of downthrow on its SE side (as reported by Kennedy 1946).
The Great Glen Fault is a major geological feature that traverses southwest to northeast across the Scottish mainland from Fort William to Inverness.
The two mantle domains tightly bracket the fault. The lamprophyre magmas were generated at depths of at least 100 km. At the end of the Caledonian Orogeny the Great Glen Fault was a major vertical discontinuity that transected the sub-continental lithospheric mantle.
Aug 12, 2024 · A popular conceptual tectonic model envisages the Great Glen Fault to be part of a sinistral strike-slip system active during the mid-Silurian through early Devonian with c. 700 km of displacement.

The Great Glen hosts the most prominent fault in the British Isles, the Great Glen Fault. 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.
