| Description: | North Lee from the roadside (A 867). North Uist, Outer Hebrides. The Outer Hebrides Thrust Zone, the culmination of the Laxfordian (Precambrian) period of deformation. The hill is formed of pseudotachylite which has welded together the otherwise broken and friable gneiss of the thrust zone making the rock more resistant to weathering and giving rise to this prominent hill. The pseudotachylite is a dense, black, flinty rock thought to have formed by the brittle fracturing of the gneiss resulting in local melting by frictional sliding. The hot molten material is injected into the adjacent gneiss to form an intricate vein network of black glass. |
