The collection of Highland rocks minerals and fossils spans three billion years of earth history, from the oldest rock in Europe to volcanic rocks extruded at the opening of the North Atlantic.
A geological relief model and diorama illustrate local thrusting during the building of the Caledonian mountains. A good collection of fossil fish, plants and crustacea give a glimpse of Lake Orcadie which covered the north east Highlands four hundred million years ago.
|The mineral room contains fluorite and haematite from British mines, Norwegian eclogite, thulite, anatase, zircon and garnet. Some breath-taking geodes, quartz and agate from Brazil lie alongside unusual crystals of rose quartz, lazulite, tourmaline and pyrite. Specimens have been chosen for their beauty and scientific interest, rather than rarity. Many are large. A collection of semi-precious stone spheres (many polished on the premises) will interest the lapidary.|
The fossil room exhibits local, British & world specimens from many stages of evolution. These include early stromatolites, trilobites, fish, ammonites, reptiles, mammals, plants and trees.
