| Description: | Traprain Law, a phonolite laccolith intruded into Lower Carboniferous sediments and volcanic rocks which form the drift-covered foreground. Taken from Balfour Monument at Blaikie Heugh, 3 km. south-west of East Linton. The phonolite laccolith of Traprain Law is related to the Garleton Hills Volcanic Rocks suite of Carboniferous igneous intrusions. The dome-shaped mass of Traprain Law reflects the upper surface of the intrusion. It is thought that the laccolith was responsible for the arching up of the surrounding sediments and lavas and the highly vesicular nature near the summit indicates that the phonolite crystallized in near-surface conditions. |
