Banded hornfels, as the name suggests is a variation of hornfels which shows alternating bands of dark and light coloured minerals, the banding is derived from the original protolith (previous rock prior to metamorphism). Likely to be a rock which forms in layers such as sandstone, shale or mudstone. Unlike the hornfels which we supply from Cumbria, this banded hornfels which comes from Kentellen, Loch Linnhe, Scotland is much less stronger and durable than the Cumbrian material, likely due to the banding of the minerals causing a structural weakness. This rock specimen is available in 3 various sizes and will come supplied in a card tray with a 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.

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.
