Cannel coal is brown to black oil shale. It is derived from resins, spores, waxes, and cutinaceous and corky materials of terrestrial vascular plants. Cannel coal was accumulated in ponds and shallow lakes in peat-forming swamps and bogs of the Carboniferous age under oxygen-deficient conditions. Cannel coal typically contains much less fixed carbon than bituminous coal. This example was obtained from the Alexander open cast pit in Wigan, Lancashire. Supplied by weight only with size of pieces being random. These rocks come in a 1 kg polythene bag with a data label.

Cannel coal by it’s physical morphology and low mineral content is considered to be coal but by its texture & organic matter content it is considered to be oil shale. Although historically the term cannel coal has been used interchangeably.

Bituminous coal is a soft sedimentary rock with a high organic content & the tar-like substance Bitumen. It is of a lower grade than Anthracite but higher grade than Lignite. Supplied in lots of 1 kg.
Anthracite coal specimens, a vitreous, high grade coal with a hard and compact nature, these samples are from the Carboniferous coalfields of South Wales, UK and are one of the coals which have fewer impurities and a high carbon contents. Available in optional sizes, each sample will come supplied in a card tray with a label.
We also supply Anthracite Coal thin sections for microscope study which are available to buy HERE.

Specimens of Lignite (Brown Coal), collected from Germany. Lignite is a soft, combustible sedimentary rock which forms by the natural compression of peat material. It has a high carbon content 25 – 35% & a moisture content up to 66%. The high volatile matter content makes it easier to convert into gas and liquid petroleum products than higher ranking coals. It is used almost exclusively for the generation of electricity in countries such as Greece & China. These pieces are Miocene in age. They are available in multiple sizes and come in a white card tray with an information label.
We also supply Lignite thin sections for microscope study which are available to buy HERE.

Specimens of Bituminous Coal, collected from the Carboniferous deposits in Yorkshire. Bituminous Coal is an organic sedimentary rock, that forms by diagenetic and sub metamorphic compression of peat bog & swamp material. Its primary constituents are macerals: vitrinite, and liptinite. The carbon content of bituminous coal is around 60-80%. The rest consists of residual water, air, hydrogen, and sulphur. These specimens are available in multiple sizes and come in a white card tray with an information label.

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.

Graphic granite is an igneous pegmatite rock from Iveland, Norway, which forms in intrusive batholithic bodies that have a felsic composition. As such, the rock is mainly composed of quartz and orthoclase feldspar crystals and lacks any mica, making the rock leucocratic. These samples have what is known as a graphic texture, due to the formation of the crystals, which result in an appearance similar to that of cuneiform text which was once used by ancient human cultures. A brightly coloured, eye catching rock, the samples are suitable for collectors and educational use at higher levels and come available in three sizes. Each specimens is supplied in a card tray with an information label.

Obsidian is a naturally occurring volcanic glass derived from a rapidly cooled high silica lava. Often associated with the margins of Rhyolitic lava flows. It has little or no discernable crystalline structure. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Syenite thin section slide. The thin sections show a dominant feldspar mass ( orthoclase ) with occurrences of hornblende, amphibole and clinopyroxene. Biotite mica may also be present however its occurrence is rare, The thin section is supplied in a protective card sleeve with a label, ideal for microscopy and educational purposes.

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.
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 ‘.

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.

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.

Rhyolite Felsite, a highly felsitic composed variation of Rhyolite, found in Fife, Scotland, an extrusive igneous rock composed of sodium, quartz and feldspar, thus often having a pale white to pink colouration. Available in various sizes and supplied in a card tray with an information label.
