Norwegian gneiss thin section slide exhibiting a dominant felsic composition i.e. quartz and plagioclase with less prominent mafic bands.The dark mafic minerals are typically biotite mica and pyroxene however in thin section view, at such a small scale, it is harder to discern these concentrated mafic accumulations as bands. In hand specimen the alternating light and dark bands, known as ‘ gneissic banding ‘ are much more clear. The alternative views of hand specimen and thin section supplement each other to allow for the most detailed rock descriptions and interpretations to be delivered. Due to the fact that this gneiss contains more feldspar and quartz and less of the dark mafic minerals, it is sometimes known as migmatitic gneiss. We collected this material from Evje, Norway. 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 and educational purposes.

Biotite gneiss is a metamorphic rock found in Evje, Norway. These specimens exhibit alternating bands of black and white minerals, derived from quartz, plagioclase feldspar and biotite mica. Giving a surreal appearance, similar to the stripes of a zebra. The samples are available in various sizes and comes supplied in a card tray with a label.

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.

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.

Lewisian gneiss from Northwest Scotland, formed during the Pre-Cambrian period, making it among the oldest rocks in the UK, pushed to the surface during an oregenic event, Lewisian gneiss exhibits banded like most gneisses but is comprised of more dark, dense minerals, often igneous in origin. Specimens are available in 3 different sizes.
Gneiss from Evje, Norway, containing more feldspar and quartz than Lewisian gneiss from Scotland, giving it a pink colour, these specimens show excellent banding and text book crystal structure, supplied in 3 sizes, ideal for educational use.
We also supply Gneiss thin sections for microscope study which are available to buy HERE.

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.

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.

Glaucophane Schist thin section microscope slide exhibiting a clear fabric and a wonderful blue hue under plane polarised light. This material was collected from the Isle of Anglesey, North Wales. Each section is made to 30 microns thickness and the glass is 46 x 27 mm, ideal for microscopy and educational purposes.

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.

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.

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.

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.

Stunning peridotite thin section exhibiting the bright and beautiful colours of olivine and pyroxene punctuated by relatively abundant plagioclase. Peridotite is a dense, coarse grained, ultramafic igneous rock consisting largely of olivine and pyroxene.

Big feldspar gabbro thin section exhibiting exactly what its name describes, feldspar crystals much larger than those present in the ordinary gabbro which we supply. Characteristic twinning in the plagioclase and the bright colours of the pyroxene make for an attractive thin section, perfect for educational use.
