| Description: | Auchengillan, 4.8 km. west of Strathblane, Stirlingshire. Classic dip and scarp featuring in lavas of the Clyde Plateau Volcanic Formation dipping to the left in the photograph. The gently-dipping steps are the tops of individual flows and the cliffs form where the erosion level jumps between successive flows. These lavas are macroporphyritic basalts of the Markle variety, with common large phenocrysts (>2 mm.) of plagioclase and a few olivine. The Midland Valley of Scotland was quite active volcanically during the early Carboniferous period, with huge volumes of basalt lava erupted, especially in the western part of the Midland Valley. Numerous contemporary basic and intermediate intrusions such as dykes, sills and plugs pierce the older sedimentary rocks. |
