| Caption: | Sill, Salisbury Craigs, Edinburgh, Mid Lothian. |
| Description: | Base of sill of intrusive teschenitic dolerite forcing aside and hardening sandy calcareous beds of cementstone age. East end of Salisbury Craigs, Arthur's Seat, Holyrood Park. A classic locality showing how the emplacement of the magma has prised up a slab of the underlying sandstone as well as hardening and baking the rock due to the very high temperature of dolerite during intrusion. The sill is one of a series of major sills up to 120 m. thick emplaced during the Dinantian to early Westphalian (Carboniferous) in the Lothians and Fife. Most of the sills are olivine dolerite or of teschenitic type. Other teschenitic sills of the Lothians include Gullane, Craigie and Blackburn. Olivine dolerite sills are more common in Fife. |
