Specimens of recent glacial clay (boulder clay till) from Beetham, Cumbria, UK. These samples of clay are glacial till which have been deposited by a glacier or ice sheet through the processes of erosion and entrainment. The deposits are relatively recent dated to approximately the Paleolithic age and are a pale brown in colour. Specimens are perfect for education but may also be ideal for any British rock collectors. Pieces are supplied in a white card tray with an information label.

Kimmeridge clay is a fine grained sedimentary rock of Jurassic age, it can contain various fossils from invertebrates to large fauna such as dinosaurs and crocodiles. These specimens come from Kimmeridge, Dorest, UK and are available in various sizes.
We also supply Kimmeridge Clay thin sections for microscope study which are available to buy HERE.
Kimmeridge clay thin section slide exhibiting the incredibly fine grained nature of this rock. Despite being so fine, individual clay grade minerals can be identified along with organics arranged in an obvious orientation. The slides are 30 microns thick and measure 46 x 27 mm in size and have a cover slip of the section along with a protective cardboard sleeve.

Oxford clay from Scarborough, North Yorkshire, a grey to green colour exhibiting a fine grained texture, these rock specimens are Jurassic in age and are available in various sizes.
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.
Specimens of Salt Pseudomorphs on a limy matrix, collected from the Triassic Aust Cliff in Avon, UK. Salt Pseudomorphs serve as important inicators of paleoenvironmental conditions. They typically form in semi arid (dry) climates, where saline water evaporates, which leaves behind cubic salt crystals. These salt crystals later dissolve, occasionally preserving their cubic imprints These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Portland Stone is a variation of limestone which formed during the Tithonian stage of the Jurassic period. It has been quarried since the 14th century, notably on the Isle of Portland, Dorset. This pale rock is sufficiently hard to resist weathering but yet soft enough to carve hence it makes an ideal architectural material. It was famously used for the construction of St. Pauls Cathedral and Buckingham Palace in London. Like most limestone, Portland stone formed in sub-tropical seas where wave action even resulted in the micro oolites visible in some pieces. Specimens are supplied in a labelled card tray.
We also supply Portland Limestone thin sections for microscope study which are available to buy HERE.

Specimens of Conglomerate, collected from Farringdon, Berkshire in the UK. Conglomerate is a term used to describe a group of coarse grained sedimentary rocks, featuring large well rounded clasts in a finer grained matrix. They were laid down in a high energy environment, either fluvial, alluvial or shallow marine. The roundness of the clasts can be an indicator of the transport distance or the action of sustained erosion. These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Specimens of Frosterley Marble, collected from Harewood Quarry, Co. Durham in the UK. Frosterley Marble is not actually a marble, but rather a black limestone consisting of Carboniferous age fossil corals. This makes it a sedimentary rock. The most famous use of Frosterley Marble is in Durham Cathedral where the ceiling of the Ceiling of the Chapel of Nine Altars has slender column supports composed from this stone. These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Specimens of Coral Limestone, collected from Anglesey. Limestone is a common, well known sedimentary rock. It consists of the calcium-rich shells, bones, and skeletons of the fauna that dominated during that period. These specimens date to the Palaeozoic era around 300 million years ago. They were laid down in shallow tropical seas around 300 million years ago, in the Carboniferous. The composition of these specimens is primarily Lithostrotion corals. They are available in multiple sizes and come supplied in a white card tray with an information label.
We also supply Coral Limestone thin sections for microscope study which are available to buy HERE.

Specimens of Mudstone, collected from Lancashire. Mudstone is a very fine grained sedimentary rock, that consists of clay minerals and tiny quartz grains. Mudstone lacks a well developed bedding structure or fissility. This lithology is typical of low energy environments, such as tidal flats, lakes or deep marine environments. These specimens date to the Carboniferous period, approximately 359 – 299 million years ago. The specimens are availeable in multiple sizes, and come in a white card tray with an information label.

Specimens of Ribbon Banded Mudstone, collected from North Wales. In particular, these specimens are Silurian in age & specifically from the Nantglyn Flag Group of the Denbigh Grit Formation. This largely grey rock shows alternating bands of fossiliferous mudstone and laminated muddy siltstone with subordinate thin pale green to yellowish lenticular bands of calcareous siltstones. These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Dolostone or dolomite rock is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. Most dolostones formed as a magnesium replacement of limestone or lime mud prior to lithification. It is resistant to erosion & less soluble than limestone in weakly acidic groundwater. Technically, dolostone has a stoichiometric ratio (reaction & product ratio) of nearly equal amounts of magnesium and calcium. This particular example comes from the Clitheroe area of Lancashire. Specimens are supplied in labelled card trays.

Specimens of Estuarine Sandstone, collected from Lancashire. Sandstone is a common, well known sedimentary rock, primarily composed of quartz grains. Estuarine sandstone as the name implies was laid down as fine cross bedded deposits at the mouths of rivers. Occasional marine incursions are evident from fossils & ripple bedding. Some of the fine beds are peppered with mica flakes. Specimens are supplied in a white card tray with information label.
We also supply Deltaic Sandstone thin sections for microscope study which are available to buy HERE.
Specimens of Oolitic Limestone, collected from Gloucestershire in the UK. Oolitic Limestone is a carbonate rock, that consists mostly of ooliths (or ooids). These are sand-sized carbonate particles (0.25 -2.0mm) built up of concentric shells of precipitated calcium carbonate (CaCO3). These layers form around sand grains or shell fragments that roll around on a shallow sub tropical sea floor, gathering layers of carbonate. Around the Cotswold Hills, the honey coloured stone has been the favoured building material for centuries. Many local picturesque hamlets showcase this. These specimens tend to be a little more friable than the examples from Yorkshire. These specimens are Mid Jurassic in age. They are available in multiple sizes and supplied in a white card tray with information label.

Specimens of Tufa, collected from Caerys, North Wales. Tufa is a variety of limestone, which forms by the precipitation of carbonate minerals from ambient temperature water bodies. These specimens date to the Quaternary period, specifically, the Flandrian epoch. It forms in fluvial channels or lacustrine environments & subterranian passages (dripstone, stalagmites & stalactites). This rock specimen is a classic tufa, light in weight, spongy, and containing many plant, preserved in the rock. Specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Tufa thin sections for microscope study which are available to buy HERE.
