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.

Ashford Black Marble – Derbyshire £2.25 – £6.00 ex VAT
Ashford Black Marble samples originate from Ashford-in-the-Water, Derbyshire, UK. Despite its name, this rock surprises many by being classified as a fine-grained Sedimentary Rock instead of a Metamorphic one. This classification is due to its true nature as a dark limestone rather than a genuine marble. Ashford Black Marble earns its reputation for ornamental purposes, showcasing a stunningly shiny black surface when cutting and polishing it. The rock’s origin dates back to the Carboniferous period, and it boasts a generous amount of bitumen, giving rise to its dark grey hue that transforms into a mesmerising glossy black appearance upon polishing. Supplied in various sizes, each specimen comes presented in a white card tray with an accompanying informative label.
