These particular specimens are of specularite crystals in a massive form, therefore the samples have a highly crystalline texture. They come from Brazil and give off a metallic shimmer when held under certain lighting. Being an iron mineral, the samples are also quite dense for their size, the anhedral crystals are also loose and will leave black marks on your hands, care is advised when handling.

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.
We also supply Aeolian Sandstone thin sections for microscope study which are available to buy HERE.
