Phonolite is an extrusive igneous rock which is not too common in the field, it has a texture which ranges from fine grained to coarse grained and an intermediate chemical composition which lies between felsic and mafic which can make samples in the field quite difficult to differentiate from more commonly rocks of a similar nature. A peculiar aspect of phonolite is the metallic sound it makes when struck, often making a ringing or clanging sound. It is this feature that led to its name, being derived from the ancient Greek word which is roughly translated to ‘sounding stone’. chemically, these rocks are similar to nepheline syenites, (which we stock from Norway) but exhibit a finer grained texture and form via partial melting of under-saturated silica along with feldspathoids  These particular specimens of phonolite are found in Traprain Law, Scotland, UK, the rock samples are supplied in a white card tray and come with an information label.

Amygdaloidal Basalt £1.73 – £3.46 ex VAT
Specimen Size
2" x 2"3" x 2"4" x 3"

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.

Garnet Peridotite £3.45 – £9.20 ex VAT
Specimen Size
1.5 " x 1.5"2" x 2"3" x 2"4" x 3"

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.

Obsidian £1.61 – £4.23 ex VAT
Specimen Size
2" x 2"3" x 2"4" x 3"

 

 

Obsidian is an extrusive igneous rock, these specimens exhibit a typical black colouration with conchoidal fractures, they come from South East Mexico and are excellent for educational use and collectors due to the quality. This igneous rock forms when magma extrudes onto the earths surface, chemically it is silica rich and impurities give the black colouration. It’s fine crystalline texture and fracture makes obsidian appear glassy and it breaks as such. The pieces are available in various sizes and come supplied in a card tray with an information label.

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.
