A coarse grained, felsic intrusive rock. The minerals which make up a granite are typically quartz, feldspars and micas. In the case of biotite muscovite granite, the constituent minerals are milky (white) quartz, plagioclase feldspar and biotite and muscovite mica crystals. The biotite appears as small black ‘flecks’ on the surface of the specimens. These particular samples come from Liskeard, Cornwall, UK. Specimens are supplied in a polythene bag in lots of 1 kg with a label.

Shap granite igneous rock specimens from Shap Fell, Cumbria, UK which exhibit typical coarse grained crystalline textures expected of intrusive felsic rocks, being composed of quartz, plagioclase and orthoclase feldspar and biotite mica. This popular granite is very sought after for a variety of applications and has a colourful appearance. It is believed to have formed during the early Devonian period as a plutonic intrusion in the area and is quarried extensively. Samples are ideal for collectors of all levels and ages as well as all educational levels as the minerals can be easily described with the origin and processes being suitable to teach higher level students. Samples are available in three sizes and come supplied in a card tray with an information label.
We also supply Shap Granite thin sections for microscope study which are available to buy HERE.
Graphic Granite is a leucocratic igneous rock found predominantly in granitic pegmatites. It’s coarse intergrowths of feldspars display a Runic or Cuneiform configuration hence the term “graphic”

Micro Granite is a variation of the granite group of rocks, composed of the minerals quartz, feldspar and mica. These particular samples were collected from Threlkeld quarry, Cumbria, UK. Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Adamellite granite also known as shap granite from Cumbria, famous for its large pink feldspar crystals his granite is well known. The samples come from the Shap Quarry, Shap Fell, Cumbria and are supplied in a polythene bag in lots of 1 kg with a label.
Biotite muscovite granite specimens from St. Austell in Cornwall, UK of Permian age is a coarse grained igneous rock composed of quartz, plagioclase feldspar, biotite and muscovite. The rock is part of the St. Austell pluton which formed 280 million years ago. An off white colour with gold and black flecks of micas, the rock has a unique chemistry and resulted in the rich mineralisation of ores in the area. The samples are suitable for collectors and educational use to show granite variants, available in three sizes. Each piece will come supplied in a card tray with an information label.

Larvikite is an igneous plutonic rock and variant of monzonite from Larvik, Norway, due to its chemistry, it is composed mainly of orthoclase, albite and anorthite along with plagioclase which gives the rock a blue to silver shimmering effect. The igneous pluton formed during the Permian period, 292 – 298 million years ago during the the Variscan orogeny. A beautiful rock to observe due to its coarse crystalline texture and schiller effect, the samples are ideal for general interest, collectors and educational use with specimens being available in three sizes and come supplied in a card tray with an information label.
We also supply Syenite thin sections for microscope study which are available to buy HERE.

Greisen metamorphic rock specimens from Caldbeck Fells, Cumbria, composed mainly of quartz and mica with an off yellow colouration. The rock is known as an endoskarn and forms when hydrothermal fluid and heat alter a granitic body, resulting a heavily altered rock which may contain trace amounts of rare elements. These samples are suitable for advanced collectors and higher level education and are available in three sizes, each pieces will come supplied in a card tray with a label.

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.
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.

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.

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.

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.
