Chert microscope slide exhibiting the interlocking crystals of quartz characteristic of this silica rich microcrystalline, cryptocrystalline sedimentary rock. The crystals are relatively large in this Foss Mine ( Scotland ) variety of chert and individual crystals of quartz can easily be distinguished in XPL view. Chert can occur as a primary deposit however it frequently occurs as a replacement mineral during diagenesis e.g. Flint nodules in Chalk. The 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.

Chert is classified as a sedimentary rock and is a hard cryptocrystalline form of silica. It is found as nodules and bands within the Cretaceous Chalk, with these samples coming from Norfolk in the UK. It is well known for its glassy crystalline texture which allows pieces to be knapped and for this, the rock was used by stone age humans to make various cutting tools and weapons as it often break, leaving sharp edges. The specimens exhibit an earthy brown colour with a waxy lustre and are available in various sizes, which will come supplied in a card tray with an information 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.

Shale microscope slide showing thin black lenses of organic matter (in XPL view) which fell from suspension in very low energy environments. The 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.

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.

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.

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.

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.
