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.

A thin section of mylonite which was collected from the metamorphic region of Lom, Central Norway. During formation, high temperatures and pressure allowed quartz crystals to recrystallise, become finer and allow the rock to flow, subsequently producing mylonite. In thin section the larger clasts are usually feldspar because they do not recrystallise as easily as quartz. Thin platy minerals of mica show a degree of alignment and can be recognised by their bright colours under crossed polars. 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.

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.

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.

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.

Rhyolite thin section slide exhibiting the fine grained nature of this felsic igneous rock. The thin section shows a silica rich mineral assemblage of fine grained quartz and plagioclase. Accessory minerals present include biotite mica and hornblende. This material was collected from Cumbria, UK.

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.

Rare eclogite thin section slides cut from our Norwegian eclogite hand specimens. Eclogite is a rare rock, composed of mainly two minerals, reddish-brown garnets and Omphacite (green pyroxene), our thin sections exhibit this clearly.

Oolitic limestone thin section slide exhibiting textbook ooid grains, some with a clear nucleus and concentric calcareous layers. These microscope slides supplement the hand specimens nicely and allow for a more detailed view of the ooid grains and an opportunity to intepret the diagenetic history of the rock.

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.

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.
