Garnet mica schist a foliated, medium-grained metamorphic rock containing small pink garnet porphyroblasts in a matrix of quartz, plagioclase feldspar, muscovite and biotite. Two lithologies are present, a quartz-rich and a mica-rich lithology. The quartz-rich lithology is dominated by quartz with subordinate plagioclase feldspar and minor biotite and muscovite. Biotite is the most abundant mica in the quartz-rich layers. The mica-rich lithology is dominated by muscovite, with minor (<20 vol%) biotite, quartz and plagioclase. Garnet porphyroblasts are present in both lithologies. These examples come from the Loch Tay region of Scotland. Specimens are supplied in labelled card trays. Supplied in 1 kilogram bags with labels.

Glaucophane Schist is also known as Blueschist. The blue-green colour comes from the dominant presence of the minerals Glaucophane (amphibole) & Lawsonite. These samples are supplied in lots of 1 kilogram and come with an information label.

Garnet mica schist from Loch Tay, Scotland, showing in excellent detail the effects of regional metamorphism along plate boundaries, the garnets push the mica crystals around it due to being stronger, the specimens are available in various sizes or as a cut and lacquered piece, supplied in a card tray with a data label.

Large Pink Gneiss rock specimens collected from Evje, Norway. Specimens also contain some Biotite and show banding. Supplied in 1 kilogram polythene bags with a data label.
Samples of graphitic schist from the Pre-Cambrian Dalradian formation, making them among the oldest rocks in the country. The samples come from the Ben Eagach schist formation at Foss mine, Scotland, UK and were collected by our own members of staff. The rock contains mica and graphite, which gives the specimens their unique mica appearance and greasy graphitic texture and lustre.

Rhyolite Felsite, a highly felsitic composed variation of Rhyolite, found in Scotland. Specimens are supplied in a polythene bag in lots of 1 kg with a 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.

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.

Pumice specimens from the Lipari islands, Italy. Pumice is an igneous rock with a highly porous structure resulting from trapped gas bubbles as the lava was being ejected. The rock is usually very light & buoyant in water. Specimens are supplied in a card tray with label.

Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.

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.

This Mahogany obsidian is sourced in the United States of America. Impurities of magnesium and iron give this variety a red or brown appearance hence the name ‘mahogany obsidian’ or oak obsidian. Specimens are supplied in a polythene bag in lots of 1 kg with a label.

Graphic granite is an igneous pegmatite rock from Iveland, Norway, which forms in intrusive batholithic bodies that have a felsic composition. As such, the rock is mainly composed of quartz and orthoclase feldspar crystals and lacks any mica, making the rock leucocratic. These samples have what is known as a graphic texture, due to the formation of the crystals, which result in an appearance similar to that of cuneiform text which was once used by ancient human cultures. A brightly coloured, eye catching rock, the samples are suitable for collectors and educational use at higher levels and come available in three sizes. Each specimens is supplied in a card tray with an information label.
