An andesite slide, a volcanic rock found in the Andes Mountains of South America. It has an intermediate, fine-grained groundmass and occasional phenocrysts of plagioclase feldspar. Andesite is an extrusive rock with a composition between rhyolite and basalt. It is similar to diorite and contains 52-63% silica, as well as pyroxene (augite) and feldspars (plagioclase). Andesite lava has moderate viscosity, resulting in thick lava flows and domes. This sample was collected from Borrowdale in the Lake District, UK, and is from the Late Ordovician period. The glass andesite slide measures 46 x 27 mm and comes with a protective card sleeve and label, making it ideal for microscopy, petrography, and education.

Diorite rock specimens from Cockermouth, Cumbria, is an intrusive igneous rock from the Ordovician period with a coarse, phaneratic texture composed of plagioclase feldspar, biotite mica as well as hornblende with intermediate chemistry. Found with the Skiddaw group, the rock samples are more suited for serious collectors and higher level education to describe the chemistry and mineralogy of various igneous groups. Available in 3 sizes and supplied in a card tray with an information label.
We also supply Diorite thin sections for microscope study which are available to buy HERE.

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.
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.

Biotite granite thin section exhibiting abundant biotite crystals within a typical granite crystal mass. These thin sections supplement the hand specimens nicely and allow the crystallisation history of the rock to be interpreted.

Diorite thin section slide. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar (typically andesine), biotite mica, hornblende, and/or pyroxene. This particular material was collected in Cumbria.

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.

Bytownite basalt thin section slide exhibiting phenocryts of bytownite feldspar within a fine basaltic groundmass. These thin sections depict beautifully a textbook porphyritic texture. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size.

Tufa thin section slide. Tufa is a variety of limestone, formed by the precipitation of carbonate minerals from ambient temperature water bodies. This particular material is from the Flandrian epoch of the Quaternary Period and it was collected in Caerwys, North Wales.

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.

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.

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.

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.

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.

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.

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.

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.

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.
