Eocene puddingstone conglomerate collected from Hertfordshire, UK. Puddingstone is a textbook a variety of conglomerate, it is composed almost entirely of silica; the smooth and rounded silicic pebbles are held firmly in place by a hard silica cement. The silicic nature of this rock makes it characteristically harder than most conglomerates and it gives the rock a slightly polished appearance. This stunning conglomerate is ideal for educational purposes but would also make a beautiful display piece or an interesting addition to a rock collection. Conglomerates form from water transported sediment, just like their counterpart breccia, however, where as breccia tends to have angular clasts (inclusions), conglomerates usually have smooth, rounded clasts, as can be seen in our specimens. This is because the rocks which make up conglomerates have been transported much further than breccia, the duration of this transport has resulted in the clasts being eroded for a much longer period of time, making them more rounded, smoother and in some cases, polished. Available by weight, supplied in a 1kg bag with an information label.

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.
Carboniferous Millstone Grit found in Lancashire, once a popular building material due to its strength. Available by weight, comes in a 1 kg bag.

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

Conglomerate with well rounded clasts from Faringdon, UK. A good example of the lithotype as opposed to a Breccia which would contain predominantly angular to sub-angular clasts. Supplied by weight in bags weighing 1 kilo.
Pink Granite, rich in potassium feldspars giving the distinctive pink hue, easily identifiable as a granite due to its mineral composition. Specimens come from Scotland and are supplied in a card tray with label.

Graphic Granite is a leucocratic igneous rock found predominantly in granitic pegmatites. It’s coarse intergrowths of feldspars display a Runic or Cuneiform configuration hence the term “graphic”

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.
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.
We also supply Shap Granite thin sections for microscope study which are available to buy HERE.
Rhyolite thin section slide exhibiting the fine grained nature of this felsic igneous rock. The thin section shows a silica rich mineral assemblage of fine grained quartz and plagioclase. Accessory minerals present include biotite mica and hornblende. This material was collected from Cumbria, UK.

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.

Peridotite, found in Finland, is a dense, coarse grained igneous rock. It is commonly used in saunas due to certain porpertie. These rock specimens are ideal teaching aids or collectors specimens. Supplied in a card tray with label, offered in 3 optional sizes.
We also supply Peridotite thin sections for microscope study which are available to buy HERE.

Metagabbro specimens from Lom, Central Norway. Also known as scapolite-hornblende due to the absence of feldspar in the rock are available in 3 optional sizes and come supplied in a card tray with a data label.

Rhyolite specimens found in Cumbria. Rhyolite is a felsic (silica rich) rock, often formed in highly explosive volcanoes. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Adamellite granite also known as shap granite from Cumbria, famous for its large pink feldspar crystals his granite is well known. The samples come from the Shap Quarry, Shap Fell, Cumbria and are supplied in a polythene bag in lots of 1 kg with a label.
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.
We also supply Snowflake Obsidian thin sections for microscope study which are available to buy HERE.
Granite adamellite thin section slide exhibiting crystals of quartz, biotite and feldspar. We collected this material from the famous Shap Fell quarry, in Cumbria hence the rocks alternative name ‘ Shap Granite ‘.
