12th May 2007 Geology field trip, Garrell Burn, Kilsyth. Leader: Jim Morrison

The northern Clyde Plateau Volcanics overlie sediments of Upper Old Red Sandstone and Inverclyde Group Carboniferous age and are overlain by Carboniferous rocks. These volcanic rocks were poured out over the sandy sediments, which were formed during a very different climatic period, of dry river beds and later a mangrove swamp. Major faulting is evident, with the rocks at the top of the Kilsyth Hills being younger than those on the lower slopes.
