Computer Code: CRRL Preferred Map Code: notEntered
Status Code: Full
Age range: Arundian Substage (CJ) — Asbian Substage (CR)
Lithological Description: The Corrie Lava Member consists of plagioclase-macrophyric basalt and trachybasalt lavas (of 'Markle' type), aphyric basaltic-trachandesite (mugearite) lavas, and lapilli-tuff and tuff-breccia beds. Derivation is thought to be from local vents (Craig, 1980).
Definition of Lower Boundary: The Corrie Lava Member is fault-bounded and the lower boundary is not seen.
Definition of Upper Boundary: The Corrie Lava Member is fault-bounded and the upper boundary is not seen.
Thickness: More than 30 m, neither lower or upper boundaries are seen
Geographical Limits: The member is restricted to the southern part of the Campsie Block and specifically to the southern side of the south-western Kilsyth Hills, north of Glasgow. The outcrop is bounded to the south by the Campsie Fault, to the north by the Bachille Fault and to the north-east by the East Bachille Fault.
