Volcanic activity in the past has shaped Scotland as we see it today. There is no other geological process that is as important in contributing to Scotland’s amazing mix of geology, creating most of our highest hills and shaping the landscape in profound ways. Volcanic rock is the basis for Scotland’s best scenery, providing building stone and locations for castles and sheltered harbours. Volcanoes make Scotland!
There have been three big episodes of igneous rock formation in Scotland in the last 450 million years, creating different rock types in varied locations across Scotland: including granite from south-west Scotland to Shetland, the more limited basalt and dolerite rocks of the central belt, and the extensive lava flows and related rocks of the west coast and islands. We’ll explore the nature of each of these three episodes, to understand the variety of rock types and outcrop patterns, and how this influences modern Scotland.
An explosive talk that will convince you that although Scotland has lovely metamorphic and sedimentary rocks, there is no doubt that its igneous rocks are the best!
