Abstract

The Central Ox Mountains is a southwest—northeast trending inlier of Dalradian rocks, mostly attributed to the Argyll Group, that lie along a major fault, the Fair Head—Clew Bay Line (FCL). Deposition was associated with rift related magmatism. These rocks were deformed, metamorphosed (up to kyanite zone) and subsequently exhumed during the mid-Ordovician Grampian Orogeny. Subsequent sinistral transpression along the FCL was associated with the emplacement of the granitoids of the Ox Mountains Igneous Complex and the development of major syn-metamorphic shear zones or ‘slides’ during the Early Devonian Acadian Orogeny. This chapter examines: evidence for early rifting along the FCL coeval with the opening of the Iapetus Ocean; Grampian deformation and metamorphism attributed to mid-Ordovician arc-continent collision; and the emplacement of the OMIC and the later development of the slides during early Devonian Acadian transpression attributed to the closure of the Iapetus Ocean.
