Microscope slide of anthracite coal, a sedimentary rock. Anthracite is a variation of coal which is crystalline and compact, it has a vitreous lustre giving it a shine, when viewed under certain angles of light. This coal, compared to others has the highest carbon content and few impurities. These slides will allow you to view the said fine, crystalline nature of the rock, which appears to show it being made up, almost entirely of carbon. 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.

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

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.

Bituminous coal thin section slide.These thin sections exhibit more air pockets then their anthracite counterpart as to be expected being the less pure, more volatile rich variety. The slides are 30 microns thick and measure 46 x 27 mm in size.

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.

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.

Torridonian sandstone thin section slide exhibiting a fine grained arenaceous nature. The Torridonian Sandstones date from the Pre-Cambrian & are amongst the oldest rocks to be found in the UK. The section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip.

Hornfels thin section microscope slide exhibiting a dark colour and a characteristic none crystalline form. Fine grains fit together like the fragments of a mosaic, this is often referred to as rough pavement or pavement structure. Larger quartz clasts are visible but these have recrystallised to form a fine, interlocking mosaic of quartz within the original grain cast.

Amygdaloidal basalt thin section slide exhibiting amygdaloids of varying sizes within a fine grained basaltic ground mass. This particular material was collected from the Isle of Skye, Scotland. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip. Supplied in a protective card sleeve with a label, ideal for microscopy.

A thin section of mylonite which was collected from the metamorphic region of Lom, Central Norway. Mylonite is a fine-grained, compact rock produced by dynamic recrystallisation of the constituent minerals resulting in a reduction of the grain size of the rock.

These thin sections exhibit beautiful crystals of olivine, pyroxene and augite, which often shows oscillatory zonation held within a matrix of plagioclase feldspar. The slides supplement the hand specimens nicely and are useful for interpreting the crystallisation history of the rock.
