Augite Granophyre is an igneous rock of fine to medium grain size and forms typically in sub volcanic to igneous intrusive bodies. This particular rock is composed mainly of quartz and feldspar crystals which interlock with one another and give the rock a granophyric texture and gives it an overall pale, off pink colouration, however, as the name implies. it also contains small, dark green and black augite crystals, a pyroxene mineral which give the pieces a slightly heavier weight due to the density of augite, which sets a nice contrast in colour between the mainly dull pink colour with speckles of dark green and black. The specimens are from Carrock Fell in Cumbria and is part of the Carrock Fell igneous complex, which comprises of multiple dyke-like intrusions of Llanvirnian age, which occurred during the Ordovician period, approximately 464 million years ago. These samples are excellent igneous pieces and are suitable for more established collectors of higher level education, such as colleges and universities, each piece comes supplied in a white card specimen tray with an information label and are available in 3 optional sizes.

Specimens of Basalt, collected from Northern Ireland. Basalt is a common, extrusive igneous rock, that forms when magma erupts and cools quickly on the Earth’s surface. These specimens are part of the Antrim lava group and date to the Tertiary period, around 60 million years ago. This is the same as the Basalt that makes up the famous Giant’s Causeway. The chemistry of these specimens suggests that the rock is olivine basalt, and comprises plagioclase feldspar, olivine and augite. These specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Basalt 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.
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.

Brockram Breccia specimens sourced from Hoff, Cumbria, UK. Breccia, a type of clastic sedimentary rock, is characterized by its coarse-grained and poorly sorted nature, containing large angular fragments embedded in a finer-grained matrix.
Brockram is a basal breccia, composed of cemented limestone and sandstone fragments originating from the Permian period. The Permian was the last period of the Paleozoic era and occurred approximately 299 – 251 million years ago.
These samples are available in various sizes and are presented in a white card tray along with accompanying information label.
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.

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.

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.
Trachyte, a common igneous rock composed of various minerals including quartz, feldpsars, micas and olivine, rock specimens come from East Lothian, Scotland and are available in optional sizes, supplied in a card tray with a label.
Metagabbro specimens from Lom, Central Norway. Also known as scapolite-hornblende due to the absence of feldspar in the rock are available in 3 optional sizes and come supplied in a card tray with a data label.

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.

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.
Garnet peridotite igneous rock specimens found in the Gusdal Olivine Pit, Åheim, Norway is an ultra mafic rock which contains high pressure and temperature minerals such as olivine and garnet crystals. Exhibiting a green colouraiton with striking red spots, these samples were pushed up to the earths crust during the Caledonian orogeny during the Ordovician and Devonian period over 400 million years ago. The specimens are dense as expected and are ideal for children and serious collectors because of the colourful appearance as well as for higher educational use to describe deep mantle material as well as orogenic processes. The hand samples are available in various sizes and come supplied in a card tray with an information label.
We also supply Garnet Peridotite thin sections for microscope study which are available to buy HERE.
