Lignite thin section slide. Lignite coal and indeed all other varieties of coal are classed as organic sedimentary rocks. It has a high carbon content 25 – 35% & a moisture content up to 66%. The high volatile component of lignite is clearly reflected in the thin section view, particularly when compared with those of higher grade coals.

Lignite thin section slide. Lignite coal and indeed all other varieties of coal are classed as organic sedimentary rocks. It has a high carbon content 25 – 35% & a moisture content up to 66%. The high volatile content makes it easier to convert into gas and liquid petroleum products than higher ranking coals. Often referred to as ‘brown coal’, it forms due to the compression of peat material. Having been under minimal compression in comparison to the higher grade coals i.e. bituminous and antracite, coarser material and plant matter is often preserved in lignite rock, this is reflected in the thin section. 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.

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.
We also supply Bituminous Coal thin sections for microscope study which are available to buy HERE.
Cannel coal thin section microscope slide exhibiting the highly organic nature of this sedimentary rock. This material was obtained from the Alexander open cast pit in Wigan, Lancashire. Ideal for microscopy, petrography & educational use.

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.

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.

Metaquartzite thin section slide exhibiting a fine, interlocking mosaic of quartz crystals characteristic of this metamorphic rock. Each section is made to 30 microns thickness and the glass is 46 x 27 mm, ideal for microscopy and educational purposes.This material was collected near Holyhead on the Isle of Anglesey, North Wales.

Pumice thin section slide exhibiting the highly vesicular nature of this extrusive igneous rock. Pumice lavas tend to be silicic or felsic which are highly viscous thus do not allow the gas bubbles to escape efficiently.This material was collected from the Lipari islands of Italy.

Old red sandstone microscope slide exhibiting the well sorted nature of this particular sediment. Excellent to observe the nature of the minerals and interpret the history of the rock. The glass slide is 46 x 27 mm in size, suitable for enthusiasts, educational use and more, it will come in card sleeve with a label.

Travertine thin section slide. Travertine is a form of limestone deposited by mineral rich springs, especially hot springs. It is formed by the rapid precipitation of calcium carbonate, often at the margins of a hot spring or in a limestone caves.

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.

Welded tuff thin section slide exhibiting a jumbled mass of irregularly sized broken clasts held in situ by finer ash particles which have become welded together. This material was collected from Cumbria, the original rock is likely rhyolite, and indeed in hand specimen the tuff almost still looks like rhyolite and appears to show a form of banding.

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.

Cordierite 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 crystals of cordierite can be seen scattered throughout the fine matrix.

Hornblende Gneiss thin section slide exhibiting an abundance of the mafic mineral hornblende, accompanied by less abundant biotite mica, quartz and feldspar. This material was collected by staff from Southern Norway. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size, ideal for microscopy and educational purposes.

Norwegian gneiss thin section slide exhibiting a dominant felsic composition i.e. quartz and plagioclase with less prominent mafic bands. We collected this material from Evje, Norway. Each section is made to 30 microns thickness and the glass is 46 x 27 mm, ideal for microscopy and educational purposes.

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.

Gabbro thin section exhibiting some of the textbook features one would expect from this coarse, mafic igneous rock. These slides supplement the hand specimens nicely and are useful for interpreting the crystalisation history of the rock.
