The Badenoch Group is a sequence of metamorphosed Tonian age sedimentary rocks that outcrop across the Central Highlands of Scotland, east of the Great Glen.
Badenoch Group rocks extend across the Monadhliath Mountains and some surrounding areas largely between the Great Glen and Ericht-Laidon fault belts though their margins are hidden beneath younger strata; Old Red Sandstone to the north and west and Grampian Group rocks elsewhere.
The former, named from the locality of Dava between Inverness and Grantown-on-Spey includes the Slochd Psammite and Flichity Semipelite formations.
The Glen Banchor sequence is believed to be between 1 and 1.5 km thick and unconformably overlain by rocks of the Grampian and Appin groups, though the boundary may be tectonic in nature.
[3] Long the subject of debate as to how they relate to surrounding rock sequences, some geologists placed the Badenoch Group within the Moine Supergroup whilst others described them as simply ‘Moine-like’.
