Dunite igneous rock specimens from the Gusdal olivine pit in Åheim, southern Norway. Composed of green olivine minerals with chromite and pyroxene crystals, the rock forms as intrusive igneous plutons in the earth mantle down to 400 km deep and displays a coarse texture and green colouration. Overall, the samples are fairly granular and weak due to their chemistry and form part of the basal gneiss complex of southern Norway. Ideal for various levels of collectors and for higher level education and research use, the samples are available in three sizes and come supplied in a card tray with an information label.

Dunite is a coarse grained intrusive igneous rock with an ultra-mafic chemistry which is rich in the mineral olivine, around 90% or more. This give the rock an overall vibrant green colouration with minor occurrences of other expected mafic mineral such as pyroxenes, chromite and magnetite which can often be seen as minute black specks within the rock. Being a plutonic in origin, the rock formed very deep underneath the earths crust, down to 400 Km deep and is a major constituent of the mantle. These particular specimens were collected by staff from the Gusdal Olivine Pit (also known as Åheim Olivine Pit) from Åheim, Norway and overall exhibit the expected coarse grained texture and colouration. They form part of the Almklovdalen peridotite massif, an ultramafic body included in the basal gneisses of Southern Norway, a complex of gneissis rocks which underlie a large area of the North West are of southern Norway which are believed to be Caledonian in origin. These samples exhibit a weak structure, even crumbling in ones hand if too much pressure is applied. This is due to the ultra-mafic chemistry of the rock, the minerals which tend to form deep within the earth are often the most unstable when exposed on the surface, as such. If left to the outside elements, these samples will weather very quickly and it is advise they are kept somewhere dry and protected. The rock is named so after its type locality of Dun Mountain near Nelson in New Zealand and was named by the German geologist Ferdinand von Hochstetter in 1859. These samples are excellent for various collectors of different levels due to its eye catching colour and intriguing chemistry and background. It is also suitable for secondary and higher level education to assist in describing deep forming plutonic bodies and their mineralogy. The specimens are available in various sizes and will come supplied in a card tray with an information label.

Bytownite basalt ( Bytownite feldspar) is another variation of the common Basalt rock. Basalt tends to to be a dark, fine, crystalline igneous rock and has a number of different variations. Bytownite feldspar is a calcium rich member of the Plagioclase family. The mineral was first described in 1835 & named for Bytown (now Ottowa) where it was found in Canada. High quality transparent examples are used to make faceted stone in the jewelllery trade. In these examples the phenocrysts are green & opaque & set in a basalt matrix. The specimens come from Cumbria, UK and are supplied in a white card tray with a label.
We also supply Bytownite Basalt thin sections for microscope study which are available to buy HERE.

Specimens of Chrome Diopside that were collected from the Gusdal Olivine Pit, Åheim, Norway. These samples are best described as chrome bearing diopside. Diopside, a vivid green pyroxene mineral, features streaks of grey chromite that creates a stunning mineral sample that would be the perfect addition to any collection. Whilst many samples of chrome diopside tend to be crystalline in nature, our samples are unique as the feature a grainier, more crumbly texture. These specimens are in limited availability, so we recommend you move fast if you wish to add these stunning specimens to your collection. They are available in a range of sizes and come supplied in a white card tray with information label.
Peridotite, found in Finland, is a dense, coarse grained igneous rock. It is commonly used in saunas due to certain porpertie. These rock specimens are ideal teaching aids or collectors specimens. Supplied in a card tray with label, offered in 3 optional sizes.

Specimens of Epidote from Michigan, USA. In particular, they have been collected from the Laurium Mine, Osceola, Houghton County. Epidote is an abundant rock forming mineral that is most commonly green in colour. These specimens date from the Stenian period, approximetely 1 – 1.2 billion years ago. These specimens are available in limited supply, with two different size options. They come supplied in a white card tray with information label.
Shap granite igneous rock specimens from Shap Fell, Cumbria, UK which exhibit typical coarse grained crystalline textures expected of intrusive felsic rocks, being composed of quartz, plagioclase and orthoclase feldspar and biotite mica. This popular granite is very sought after for a variety of applications and has a colourful appearance. It is believed to have formed during the early Devonian period as a plutonic intrusion in the area and is quarried extensively. Samples are ideal for collectors of all levels and ages as well as all educational levels as the minerals can be easily described with the origin and processes being suitable to teach higher level students. Samples are available in three sizes and come supplied in a card tray with an information label.
We also supply Shap Granite thin sections for microscope study which are available to buy HERE.
Larvikite is an igneous plutonic rock and variant of monzonite from Larvik, Norway, due to its chemistry, it is composed mainly of orthoclase, albite and anorthite along with plagioclase which gives the rock a blue to silver shimmering effect. The igneous pluton formed during the Permian period, 292 – 298 million years ago during the the Variscan orogeny. A beautiful rock to observe due to its coarse crystalline texture and schiller effect, the samples are ideal for general interest, collectors and educational use with specimens being available in three sizes and come supplied in a card tray with an information label.

Specimens of Puddingstone, collected from Hertfordshire, UK. Puddingstone is a variation of conglomerate, which is term used to describe a coarse grained sedimentary rock, featuring large, well rounded clasts in a finer grained matrix. It dates back to the Paleocene to Eocene period around 56 millions years ago. This particular rock is composed almost entirely of silica and has no porosity, likely contributing to its notorious hardness. This rare rock is only found in quantity at one locality in Hertfordshire. As such, it is becoming exceedingly difficult to obtain. This rock is available in multiple sizes and each piece comes supplied in a white card tray with information label.
