| Caption: | Traprain Law from the south-east. East Lothian. |
| Description: | 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. A laccolith is an intrusive dome-like mass of igneous rock which arches the overlying sediment and which has a more or less flat floor. A phonolite is an undersaturated (with silica) trachyte. It is a phonolite laccolith intruded into Lower Carboniferous sediments and volcanic rocks which form the drift-covered foreground. It is related to the Garleton Hills Volcanic Rocks suite of Carboniferous igneous intrusions. |
