Microscope slides of Quartz from Madagascar, these slides display the crystal structure of the mineral on a microscopic level which assists in the identification of this mineral in other slides. Quartz is the most common mineral found at the surface of the earth and rock crystal is one of the most common, colourless, it is fairly hard and on some of the larger surfaces may show a conchoidal fracture. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size, supplied in a protective card sleeve with a label, ideal for microscopy & educational use.

Milky quartz mineral specimens from Norway, with a pale white colouration, hence the name, sometimes also known as white quartz, snow quartz or simply quartz. These particular samples were collected by staff from Iveland, Norway. This locality is also where we collected the smokey quartz from. It is in a massive form and has a very fine crystalline texture, this also results in it sometimes being sharp, so caution is advised when handling these samples. It is available in various sizes and supplied in a card tray with an information label.
Rutilated quartz is a variation of quartz which contains thin fibrous rutile crystals within it, often randomly orientated. Rutiles are a titanium mineral, dense and black, it is a common accessory mineral in high-temperature and high-pressure metamorphic rocks and in igneous rocks but found in very few locations around the world. These mineral specimens are of a dull, sometimes yellow coloured quartz which contain the rutile crystals.Where as most minerals devalue when they contain impurities or inclusions, rutilated quartz is in fact often prized for this very reason. These samples are available various sizes and will come supplied in a card tray with an information label.
Smokey quartz mineral specimens collected from Iveland, Norway, these highly crystalline samples are a dark grey colour and may have sharp edges, caution is advised. The colour is due to natural irradiation during the formation process, samples are available in various sizes and come supplied in a card tray with a data label.
Rock crystal mineral specimens from Madagascar, part of the quartz family of minerals, rock crystal is the clear or transparent variation of quartz, the most common mineral at the earths surface. These samples may show a conchoidal fracture and are suitable for collectors, enthusiast or educational use. Supplied in a card tray with an information label.
Rose quartz is a well know variation of quartz, easily identifiable due to its rose pink colouration, these fine crystalline mineral specimens are ideal as gifts, collectors, enthusiast and for use in education. These samples come from Namibia, Africa and the colour is due to iron impurities during the time that the quartz was forming, which tends to be a hydrothermal mineral and forms in veins. These specimens are very crystalline and may have sharp edges, care is advise when handling. They can be supplied in a range of sizes and supplied in a card tray with an information label.

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.

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.

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.

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.

Metaquartzite thin section slide exhibiting a fine, interlocking mosaic of quartz crystals characteristic of this metamorphic rock. Each section is made to 30 microns thickness and the glass is 46 x 27 mm, ideal for microscopy and educational purposes.This material was collected near Holyhead on the Isle of Anglesey, North Wales.

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.

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.

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.
