Description: Dolerite sill in cliff overhanging the River Nethan a little below Craignethan Castle, 7.2 km. west-north-west of Lanark, Lanarkshire. Sill of quartz-dolerite intrusive into shales of the Lower Limestone Formation, Clackmannan Group (Carboniferous). Thick sandstones form the upper part of the cliff and the 'Edge Coals' have been mined at about the level of the lowest part seen in the photograph. Scotland was quite active volcanically during the early Carboniferous period, with huge volumes of basalt lava erupted in the Clyde Plateau Volcanic Formation. Numerous contemporary basic and intermediate intrusions such as dykes, sills (as here) and plugs pierce the older sedimentary rocks.
