Scotland's rocks and minerals
Scotland has a rich geological history and incredibly diverse geology. The geology of Scotland today may be viewed as a series of five geologically distinctive areas or foundation blocks.
These foundations blocks formed far apart hundreds of millions of years ago. They eventually came together during massive continental collisions around 480 to 425 million years ago. Once its foundations became joined, Scotland drifted northwards, across the equator to it present position. During this journey, new layers of rock formed, as sediments accumulated and were buried. This occurred in a variety of environments from deep oceans and shallow seas to deserts, swamps and lakes.
Many rare, spectacular and precious minerals occur in Scotland's rocks. Lead, silver, gold, manganese, baryte, zinc, chromium, copper, mica and talc have all been mined in Scotland. Old mine sites also often host rare or unique minerals. Decorative, precious and semi-precious stones such as sapphire, blue topaz, Cairngorm crystal (smokey quartz), agates and amethyst have been collected in Scotland, and in some cases are still found.
