Description: | Tinto from Symington, Lanarkshire. Looking west. Felsite intrusion. The high ridge of the Tinto felsite intrusion actually consists of a ridge of hills: Scaut Hill, Howgate Hill, Lochlyock Hill and Tinto itself. The intrusion is in the form of a laccolith which is intruded into sandstones and conglomerates of the Greywacke Conglomerate Formation, Lanark Group (formerly Lower Old Red Sandstone), of Lower Devonian age. The crag feature on the left is due to the oligoclase-dacite intrusion of the Pap Craig. A laccolith is a generally circular to oval-shaped sill-like intrusion in the form of a lens, with its lower surface flat and the rocks above pushed up to form a shallow dome. |
