Upper Old Red Group [Offshore]

Computer Code: UPOR Preferred Map Code: notEntered
Status Code: Full, pending ratification
Age range: Late Devonian Epoch (DU) — Courceyan Substage (CF)
Lithological Description: Mainly fluvial, terrestrial sediments of Late Devonian to Early Carboniferous.
Definition of Lower Boundary: The group rests conformably on Givetian to early Frasnian marine beds (Kyle Group) near the international median line (Cameron 1993), and possibly also in northern Quadrant 44 (Cameron et al. 1992). Elsewhere, it is likely to rest on deformed Lower Paleozoic strata.
Definition of Upper Boundary: The Upper Old Red Group generally underlies Permian or younger strata, but is conformably overlain by the Cementstone Formation along the southern flank of the Mid North Sea High.
Thickness: none recorded or not applicable
Geographical Limits: The Upper Old Red Group extends eastwards from the coast of southeast Scotland along the crest and southern flank of the Mid North Sea High; its distribution farther south is unknown.
