Phyllite is a type of foliated metamorphic rock created from a slate or pelite protolith that has further metamorphosed so that very fine grained white mica achieves a preferred orientation. It is primarily composed of quartz, sericite mica, and chlorite. Sometimes minute crystals of graphite, sericite, or chlorite, or the translucent fine-grained white mica, impart a silky, sometimes golden sheen to the surfaces of cleavage, called “phyllitic luster”. These examples are from Kinlochleven, Scotland. Specimens are supplied in a labelled card tray.

Puddingstone
Puddingstone Conglomerate £1.50 – £6.00 ex VAT

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.

Graphic Granite
Graphic Granite £2.25 – £6.00 ex VAT

Graphic granite is an igneous pegmatite rock from Iveland, Norway, which forms in intrusive batholithic bodies that have a felsic composition. As such, the rock is mainly composed of quartz and orthoclase feldspar crystals and lacks any mica, making the rock leucocratic. These samples have what is known as a graphic texture, due to the formation of the crystals, which result in an appearance similar to that of cuneiform text which was once used by ancient human cultures. A brightly coloured, eye catching rock, the samples are suitable for collectors and educational use at higher levels and come available in three sizes. Each specimens is supplied in a card tray with an information label.

Shap Granite (Monzogranite) £2.25 – £6.00 ex VAT

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.

Snowflake Obsidian
Obsidian (Snowflake) £2.50 – £8.00 ex VAT

Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.

Essexite (olivine monzogabbro) £2.25 – £6.00 ex VAT

Essexite igneous rock specimens from Lanarkshire, Scotland, UK, also known as olivine or nepheline monzogabbro is an intrusive rock with mafic chemistry, composed of nepheline and plagioclase feldspar along with olivine, magnetite minerals as well as augite phenocrysts which exhibit euhedral crystal forms. The rock has a dense weight and overall dark colouration but attractive appearance. It is locally known as Crawfordjohns and was highly sought after as a high quality material to produce curling stones. These samples are excellent for young and older collectors as well as higher educational use, the pieces are available in three sizes and come supplied in a card tray with an information label.

Bytownite Basalt £2.25 – £6.00 ex VAT

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.

Aeolian Sandstone
Aeolian Sandstone £2.25 – £6.00 ex VAT

Specimens of Aeolian Sandstone collected from Lazonby, near Penrith, Cumbria in the UK. This aeolian sandstone is Triassic in age – approximately 200 Ma. It belongs to the group of rocks known as the New Red Sandstone which date from the Permian (280 Ma) into the Triassic. The composition of this sandstone consists solely of spheroidal (millet seed) quartz grains with an iron oxide cement called haematite. It is the presence of this haematite that contributes to the distinct red – orange colouration of these samples. This lithology is typical of an aeolian (wind blown) hot desert environment. Available in multiple sizes, these specimens come supplied in a white card tray with information label.
