ROCKS, MINERALS AND FOSSILSRock specimens available in this section. We are the UK’s leading supplier of rock specimens, by single specimens of various sizes to rocks supplied by weight in lots of 1 kg. With over 30 years years experience and 3 geologists in our warehouse, we will have what you require. Geological rock specimens are ideal for educational & private use & in collections as well as being an important part of education both with science and in geological or earth science specific subjects. Our rocks specimens are sourced from around the world, and in some cases, the majority of UK & Norwegian samples are collected by our staff members them selves.
STORAGE AND DISPLAYStorage items such as specimen trays and die cut boxes can be found here such as folding card trays, boxes and cell sections. These items will allow you to safely store you geological rock, mineral or fossil specimens and collections to prevent them from damage, dust and corrosion.

BOOKS AND GUIDESEntire range of Geological maps of the British isles produced & published by the British Geological Survey (BGS). Geological maps are often in 1:50 000 scales and are set out similar to OS maps, but instead details the geology of the local area from the bedrock to recent superficial deposits. We also stock the full range of 1:25 000 scale maps as well as even smaller scales. All maps are supplied folded for ease of use in the field.

Basalt £2.25 – £6.00 ex VAT
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.

Biotite Muscovite Granite £2.25 – £6.00 ex VAT
Biotite muscovite granite specimens from St. Austell in Cornwall, UK of Permian age is a coarse grained igneous rock composed of quartz, plagioclase feldspar, biotite and muscovite. The rock is part of the St. Austell pluton which formed 280 million years ago. An off white colour with gold and black flecks of micas, the rock has a unique chemistry and resulted in the rich mineralisation of ores in the area. The samples are suitable for collectors and educational use to show granite variants, available in three sizes. Each piece will come supplied in a card tray with an information label.

Diorite £2.25 – £6.00 ex VAT
Diorite rock specimens from Cockermouth, Cumbria, is an intrusive igneous rock from the Ordovician period with a coarse, phaneratic texture composed of plagioclase feldspar, biotite mica as well as hornblende with intermediate chemistry. Found with the Skiddaw group, the rock samples are more suited for serious collectors and higher level education to describe the chemistry and mineralogy of various igneous groups. Available in 3 sizes and supplied in a card tray with an information label.

Gabbro £2.25 – £6.00 ex VAT
Gabbro igneous rock specimens from Balmedie quarry, Aberdeen, Scotland which exhibit a coars grained texture from the crystals. Formed as a mafic pluton intrusion, the samples contain pyroxenes such as augite along side plagioclase feldspar, amphibole and olivine crystals. They are derived from a body known as the Belhelvie basic intrusion which the parent unit being the Caledonian Supersuite. Samples exhibit a grey colouration and density and are suitable for the more serious or professional collector or higher educational use to differentiate similar looking igneous rocks with different compositions and origins. Available in three sizes, the specimens come supplied in a card tray with an information label.
