Peridotite slide, showcasing the prominent presence of olivine and pyroxene, punctuated by relatively abundant plagioclase. Peridotite, a dense and coarse-grained ultramafic igneous rock, consists primarily of olivine and pyroxene. These slides serve as excellent supplements to hand specimens, providing valuable insights into the rock’s crystallization history.
Peridotite derives from the Earth’s mantle, either as blocks and fragments or through crystallization from mantle-generated magma. We personally collected this material from Finland, ensuring its authenticity and quality. Each peridotite slide undergoes meticulous crafting, resulting in a precise thickness of 30 microns. They are carefully mounted on a 46 x 27 mm glass slide and supplied in a protective card sleeve with a labeled cover, perfectly suited for microscopy enthusiasts.

Dunite Peridotite thin section microscope slide. In XPL view these thin sections exhibit the bright and beautiful second order interference colours of olivine. The high relief, lack of cleavage and distinctive fracturing is clearly evident in PPL view making for a very attractive thin section.

Andesite thin section microscope slide exhibiting an intermediate, fine grained groundmass with occasional phenocrysts of plagioclase feldspar.This material was collected from Borrowdale in the Lake District, UK & is of Late Ordovician age. The glass is 46 x 27 mm in size, supplied in a protective card sleeve with a label, ideal for microscopy, petrography and educational use.

Dunite igneous rock specimens from the Gusdal olivine pit in Åheim, southern Norway. Composed of green olivine minerals with chromite and pyroxene crystals, the rock forms as intrusive igneous plutons in the earth mantle down to 400 km deep and displays a coarse texture and green colouration. Overall, the samples are fairly granular and weak due to their chemistry and form part of the basal gneiss complex of southern Norway. Ideal for various levels of collectors and for higher level education and research use, the samples are available in three sizes and come supplied in a card tray with an information label.

Peridotite, found in Finland, is a dense, coarse grained igneous rock. It is commonly used in saunas due to certain porpertie. These rock specimens are ideal teaching aids or collectors specimens. Supplied in a card tray with label, offered in 3 optional sizes.

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.

Purbeck Limestone thin section slide exhibiting densely pack shells of varying fauna. This rock is particularly interesting in thin section; numerous shells from varying organisms such as bivalves and gastropods along with numerous signs of mineral replacement and dissolution offers an opportunity to interpret the complex diagenetic history of the rock.

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.

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.

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.

Microgranite thin section slide exhibiting the medium grained nature of this intrusive igneous rock. The crystals in microgranite are smaller than those of normal granite indicating that it cooled at a quicker rate.
We provide a full range of igneous, sedimentary, metamorphic and mineral thin sections. Click here to view them. Should you require a microscope, they can be found here.

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.

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.

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.

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.

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.
