| Caption: | Sill, Salisbury Craigs, Edinburgh, Mid Lothian. |
| Description: | The base of a sill of intrusive teschenitic dolerite is seen forcing aside and hardening sandy calcareous beds of Carboniferous cementstone age. East end of Salisbury Craigs, Arthur's Seat, Holyrood Park. This exposure was cited by James Hutton in the late 18th century as evidence for the forceful intrusion of magma. Other teschenitic sills of the Lothians include Gullane, Craigie and Blackburn. Olivine dolerite sills are more common in Fife. Hutton was the founder of what is known as the 'Scottish School of Geology'. His celebrated theory of the earth proposed a cycle of geological processes. He believed in the importance of heat in producing rocks and along with Playfair and Hall became known as the 'Vulcanists' who belived some rocks were formed from hot magmas. |
