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.

Specimens of Glaucophane Schist, collected from the Isle of Anglesey, North Wales. Glaucophane Schist is a Blueschist, which forms when basalts and similar rocks undergo high pressure and low temperature metamorphism. Specimens come in lots of 1kg, in a heavy duty polythene bag. Pieces come in various sizes.

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.

Dalradian mica schist is a famous metamorphic rock, composed mostly of the minerals muscovite mica with occurrences of quartz and feldspar, these rock specimens are Pre-Cambrian in age and come from Scotland, supplied in a card tray with an information label.
We also supply Mica Schist thin sections for microscope study which are available to buy HERE.

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.

Obsidian is an extrusive igneous rock, these specimens exhibit a typical black colouration with conchoidal fractures, they come from South East Mexico and are excellent for educational use and collectors due to the quality. This igneous rock forms when magma extrudes onto the earths surface, chemically it is silica rich and impurities give the black colouration. It’s fine crystalline texture and fracture makes obsidian appear glassy and it breaks as such. The pieces are available in various sizes and come supplied in a card tray with an information label.
We also supply Obsidian thin sections for microscope study which are available to buy HERE.
Rhyolite specimens found in Cumbria. Rhyolite is a felsic (silica rich) rock, often formed in highly explosive volcanoes. Specimens are supplied in a polythene bag in lots of 1 kg with a label.

Obsidian is a naturally occurring volcanic glass derived from a rapidly cooled high silica lava. Often associated with the margins of Rhyolitic lava flows. It has little or no discernable crystalline structure. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Accretionary lapilli tuff is an igneous pyroclastic rock, these samples come from Longsleddle, Cumbria in the UK and forms when hot ash and debris is ejected from as volcano. Some of this material is held together by moisture and once heavy enough, falls into the ash below forming small ‘spots’ within the material, creating a speckled rock. The samples are suitable both for young and serious collectors as well as educational use and are supplied in various sizes with a card tray and label.
