The Omagh Thrust Fault is a geological fault in County Tyrone. It is of one of the most important structural discontinuities in Northern Ireland [1] and an extension of the Highland Boundary Fault which runs through Scotland. [2]

The fault occurred in the Caledonian orogeny, during a late stage of this period of mountain building. Older sequences of Dalriadan metamorphic strata were moved over younger Ordovician ones with the fault as their boundary.

There is access to a view of the fault at Mountfield Quarry, County Tyrone. This has been designated an Area of Special Scientific Interest. [1]
