Chiastolite slate is rock formed by contact metamorphism of carbonaceous shale, characterized by prominent cleavage or schistosity and the presence of conspicuous chiastolite crystals in a fine-grained matrix, the rock, unlike the classic slate is actually quite soft and friable. Chiastolite is a variant of the mineral andalusite and is present in these samples as numerous thin, white lines with random orientation, with their presence indicating peak temperatures. These particular specimens come from Cumbria, UK and are available in various sizes to choose from and will be supplied in a card tray with an information label.

Shale
Shale £2.25 – £6.00 ex VAT

Specimens of Shale, collected from Yorkshire. Shale is a fine grained, clastic sedimentary rock composed of mud. This mud is a mixture of clay mineral flakes and tiny fragments of other minerals, especially quartz and calcite. Shale is characterised by thin laminae, parallel layering or bedding, less than one centimetre in thickness. This makes the rock very fissile. Shales are associated with quiet water deposition, such as in lakes, lagoons or deltas. For these specimens in particular, the depositional environment was deep water marine from the Jurassic formations of the Yorkshire coast. These specimens are available in multiple sizes and come supplied in a white card tray with information label.

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.

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.
