Garnet peridotite igneous rock specimens found in the Gusdal Olivine Pit, Åheim, Norway is an ultra mafic rock which contains high pressure and temperature minerals such as olivine and garnet crystals. Exhibiting a green colouraiton with striking red spots, these samples were pushed up to the earths crust during the Caledonian orogeny during the Ordovician and Devonian period over 400 million years ago. The specimens are dense as expected and are ideal for children and serious collectors because of the colourful appearance as well as for higher educational use to describe deep mantle material as well as orogenic processes. The hand samples are available in various sizes and come supplied in a card tray with an information label.
We also supply Garnet Peridotite thin sections for microscope study which are available to buy HERE.

Olivine dolerite igneous rock specimens from Clee Hill, Shropshire, UK, composed of pyroxene minerals such as augite and magnetite as well as plagioclase feldspar. The samples are fine grained and crystalline in texture with a dense weight and black colouration. Similar in appearance to gabbro and basalt, the rock samples are suitable for serious collectors or higher level education to explain the difference in chemistry and mineralogy of igneous rocks. The samples are available in three sizes and supplied in a card tray with an information label.
We also supply Olivine Dolerite thin sections for microscope study which are available to buy HERE.
