Specimens of Basalt, collected from Northern Ireland. Basalt is a common, extrusive igneous rock, that forms when magma erupts and cools quickly on the Earth’s surface. These specimens are part of the Antrim lava group and date to the Tertiary period, around 60 million years ago. This is the same as the Basalt that makes up the famous Giant’s Causeway. The chemistry of these specimens suggests that the rock is olivine basalt, and comprises plagioclase feldspar, olivine and augite. These specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Basalt thin sections for microscope study which are available to buy HERE.

Amygdaloidal basalt is an igneous rock which is extrusive in nature, these specimens formed over 60 million years ago during the Tertiary period and come from Ireland. They are part of the Antrim lava group and exhibit a dark colouration with occurrences of amygdales containing quartz and calcite crystals. As a basalt they are somewhat dense, but lighter than pure samples due to the cavities within them which formed as a result of gaseous activity during their ejection. Over time, hydrothermal fluids pass through the rock and minerals form within the cavities, which gives the usually dark coloured rock a speckled appearance. These samples are available in various sizes and are suitable for higher educational use to detail the subtle differences between similar igneous rocks, they come supplied in a card tray with an information label.

Streak plates in a black colour made form porcelain, tough and ideal for performing streak tests, to asses minerals or mineral content of a rock sample, each plate is 45 x 45 mm in size and has a fine texture surface. Excellent for field geologists and earth science students.
Augite granophyre igneous rock specimens from Carrockfell, Keswick in Cumbria, UK. Excellent pieces exhibiting a medium grain size of crystals which constitute this rock including, augite, quartz and feldspars and shows a granophyric texture. Suitable for avid collectors and higher educational use, the samples come supplied in a sized card tray with an information label.

Biotite granite igneous rock specimens from Ballachulish, Scotland, UK. Composed of the felsic minerals quartz and feldspar, with occurrences of biotite crystals. The rock has an overall white appearance due to its felsic chemistry but the black biotite mica offers a striking contrast in colours. The samples are ideal for both collectors due to the attractive nature and for college to university level education to describe the variations in granite which one may find. The samples are available in three sizes and supplied in a card tray with an information label.

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.
We also supply Dunite thin sections for microscope study which are available to buy HERE.
A ten specimen metamorphic rock set produced by our selves at our warehouse in the UK, the set comprises of ten samples picked out to details textures and features such as foliation, banding, high temperature or pressure minerals and more pertaining to the various grades of metamorphism. The samples sit within a plastic cell inset which its self is housed within a blue sturdy card box with a lid. The inside of the lid also has a colour photo key chart which exhibits pictures of the specimens as well as names and locations they are from. An excellent basic set for educational use or as a gift.

Specimens of Flint, collected from South Devon in the UK. Flint, a variety of Chert, is a micro crystalline, sedimentary rock. It is part of the silicate family and has a conchoidal fracture. These specimens display a monochromatic black interior, offset by a distinct white exterior. These specimens are available in various sizes and come in a white card tray with an information label.
Trachyte, a common igneous rock composed of various minerals including quartz, feldpsars, micas and olivine, rock specimens come from East Lothian, Scotland and are available in optional sizes, supplied in a card tray with a label.
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.
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.

Samples are available in 3 sizes and will come supplied in a card tray with an information label.
We also supply Andesite thin sections for microscope study which are available to buy HERE.
Agglomerate igneous rock specimens from Scotland, UK. A coarse grained, hard blocky rock exhibiting a conglomeration of various minerals and igneous material of volcanic origin. These samples formed part of the Glen Coe caldera and are apart of the upper streaky andesite unit, the exhibit poor sorting and orientation of material which indicates a somewhat violent origin but this can vary from agglomerates by location and is mainly down to the chemistry of the igneous material. The samples are available in 3 sizes and come supplied in a card tray with a label, they are suitable for educational use to show the different types of volcanic rocks produced as well as those interested in collecting rock samples.
