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. This example is from the Carboniferous of Derbyshire. Samples come by weight in bags of 1 kilo, sizes will vary.

Torridonian Sandstone from Loch Kishorn, Scotland. The sandstone of pre-cambrian age and among the oldest rocks found in the British isles and gets its name from Torridon where it is found. Supplied by weight, sizes vary.
Specimens of Sandstone, collected from Philpots Quarry, West Sussex, in the UK. This sandstone is from the Wealden Group (Hastings sub-group), which dates it to the Lower Cretaceous. This makes these rocks approximately 110 million years old. This Cretaceous sandstone is yellow to buff in coloured, and particularly fine grained. It exhibits large scale cross bedding, which is indicative of fast flowing tidal currents. It is quite soft , friable and flaggy in places and so is extracted mainly for concreting and building sand. These specimens are available in multiple sizes and come supplied in a white card tray with information label.
We also supply Cretaceous Sandstone thin sections for microscope study which are available to buy HERE.

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.
This granite pegmatite contains large sheets of muscovite mica, orthoclase feldspar and quartz matrix. An excellent teaching material which comes from Southern Norway. Each specimen comes in a labelled card tray.

Pumice specimens from the Lipari islands, Italy. Pumice is an igneous rock with a highly porous structure resulting from trapped gas bubbles as the lava was being ejected. The rock is usually very light & buoyant in water. Specimens are supplied in a card tray with label.
We also supply Pumice thin sections for microscope study which are available to buy HERE.

Microgranite thin section slide exhibiting the medium grained nature of this intrusive igneous rock. The crystals in microgranite are smaller than those of normal granite indicating that it cooled at a quicker rate.
We provide a full range of igneous, sedimentary, metamorphic and mineral thin sections. Click here to view them. Should you require a microscope, they can be found here.

Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.

Micro Granite is a variation of the granite group of rocks, composed of the minerals quartz, feldspar and mica. These particular samples were collected from Threlkeld quarry, Cumbria, UK. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Obsidian, also known as ‘volcanic glass’ is a felsic, extrusive igneous rock. Crystal growth is minimal / absent within obsidian due to rapid solidification rates which inhibit crystal growth thus giving the rock a glassy appearance.

Rhyolite Felsite, a highly felsitic composed variation of Rhyolite, found in Scotland. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
This Mahogany obsidian is sourced in the United States of America. Impurities of magnesium and iron give this variety a red or brown appearance hence the name ‘mahogany obsidian’ or oak obsidian. Specimens are supplied in a polythene bag in lots of 1 kg with a label.

Shap granite igneous rock specimens from Shap Fell, Cumbria, UK which exhibit typical coarse grained crystalline textures expected of intrusive felsic rocks, being composed of quartz, plagioclase and orthoclase feldspar and biotite mica. This popular granite is very sought after for a variety of applications and has a colourful appearance. It is believed to have formed during the early Devonian period as a plutonic intrusion in the area and is quarried extensively. Samples are ideal for collectors of all levels and ages as well as all educational levels as the minerals can be easily described with the origin and processes being suitable to teach higher level students. Samples are available in three sizes and come supplied in a card tray with an information label.
