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.

Accretionary lapilli tuff is an igneous pyroclastic rock which is often formed when material produced by the volcanic activity is ejected into the air, although it can also be used to describe similar material which has been ejected and falls from the air during meteorite impacts as well. It is seen as more of a size distinction, with material between 2 – 64 mm being being lapilli, anything less is referred to as ash and anything greater volcanic bombs or blocks. These particular specimens how ever also exhibit an accretionary feature which is sometimes known as ‘birds eyes’. They appear as numerous elongated glassy dots on the surface of the specimens and are formed when volcanic particles in an ash cloud mix with moisture in the air which eventually form a sort of hailstone, composed mostly of ash and volcanic material, held together by moisture. As the particles get heavier, they fall downward onto the material below, creating a ‘dotted’ feature on the rock. These rock specimens come from Longsleddle, Cumbria, in the UK. They are ideal for collectors due to their unique speckled feature and formation process, but also suitable for educational use of all levels as the samples are both informative for explaining volcanic processes to higher level students and intriguing for young students. Available in various sizes which you can choose from, and will come in a card tray with an information 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.
We also supply Biotite Muscovite Granite thin sections for microscope study which are available to buy HERE.

Andesite igneous rock specimens of late Ordovician age which form part of the Barrowdale volcanic group. The rocks come from Cumbria, UK and have a dark colouration with a blue tint and may contain augite crystals. The rocks are intermediate in chemistry and suitable for higher level education to explain the difference in various igneous groups. Samples are available in 3 sizes and will come supplied in a card tray with an information label.
We also supply Andesite thin sections for microscope study which are available to buy HERE.
Rhyolite Felsite, a highly felsitic composed variation of Rhyolite, found in Fife, Scotland, an extrusive igneous rock composed of sodium, quartz and feldspar, thus often having a pale white to pink colouration. Available in various sizes and supplied in a card tray with an information label.

Agglomerate igneous rock specimens from Scotland, UK. A coarse grained, hard blocky rock exhibiting a conglomeration of various minerals and igneous material of volcanic origin. These samples formed part of the Glen Coe caldera and are apart of the upper streaky andesite unit, the exhibit poor sorting and orientation of material which indicates a somewhat violent origin but this can vary from agglomerates by location and is mainly down to the chemistry of the igneous material. The samples are available in 3 sizes and come supplied in a card tray with a label, they are suitable for educational use to show the different types of volcanic rocks produced as well as those interested in collecting rock samples.
The Estwing E6-24PC geological hammer, also known as the ‘Big Blue’ hammer is a pointed tip strike tool which features a wider flat face, delivering more force per strike, making breaking and crushing of rock much easier. It also features a pointed tip, suitable for picking and prying material as well as allowing careful extraction of fossils or crystals from matrix. The hammer is made from a single piece of drop forged American steel and utilises a anti shock vinyl handle for comfort.

Quartz monzonite igneous rock specimen from Ratagan, Scotland. Associated to granites, yet containing only 5% to 20% quartz, making it a monzonite, these intrusive felsice rocks are igneous in origin and are available in different sizes, supplied in a white card tray with a label.

Granodiorite specimens from Cumbria, UK. These rocks originate from the Ordovician era, dating back roughly 443 to 448 million years. This Granodiorite, derived from Eskdale granite outcrops, exhibit a coarse-grained texture and represents a blend of granite and diorite characteristics.. While sharing mineral components like quartz, feldspar, and mica with granites, its distinctiveness lies in the elevated levels of plagioclase and mafic minerals like biotite, hornblende, and augite. Notably, this specific Granodiorite variety boasts a significant biotite content. Available in three different sizes, these specimens come supplied in a white card tray with information label.
We also supply Granodiorite thin sections for microscope study which are available to buy HERE.
An off white coloured streak plate made form porcelain, they are used by field geologists and students as a means of performing streak tests on minerals. This test simply involves one, scratching the surface of the tile with a particular rock or mineral, the coloured streak left behind then assists the user in determining the mineral, or minerals within a rock sample.
Specimens of clear quartz crystal beds within basalt from Barras, Kincardineshire, Scotland. Pieces are supplied in a card tray with an information label. These are ideal samples for collectors of British minerals and rocks.

A ten specimen metamorphic rock set produced by our selves at our warehouse in the UK, the set comprises of ten samples picked out to details textures and features such as foliation, banding, high temperature or pressure minerals and more pertaining to the various grades of metamorphism. The samples sit within a plastic cell inset which its self is housed within a blue sturdy card box with a lid. The inside of the lid also has a colour photo key chart which exhibits pictures of the specimens as well as names and locations they are from. An excellent basic set for educational use or as a gift.

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.
