Specimens of Phyllite, collected from Cumbria, UK. Phyllite is a rock that comes from when a slate or pelitic protolith undergoes further metamorphism. This results in the mica minerals achieving a preferred orientation. Phyllite features foliation, which are repetitive layers within metamoprhic rocks. Specimens come in lots of 1kg, in a heavy duty polythene bag. Pieces are of various sizes.

Metaquartzite specimens found in Anglesey, Specimens are supplied in a polythene bag in lots of 1 kg with a label.
Specimens of Phyllite collected from Kinlochleven in Scotland. This metamorphic rock has a silky, sometimes golden finish to its surface. Specimens are available in multiple sizes and comes in a white card tray with an information label.
We also supply Phyllite thin sections for microscope study which are available to buy HERE.
Lewisian Gneiss; Pre- Cambrian metamorphic rocks that outcrop in the North West of Scotland. Formed by high grade regional metamorphism of granites & sedimentary rocks. Supplied in lots of 1 kg.
Slate is a fine-grained, foliated, homogeneous metamorphic rock derived from a shale-type protolith composed of clay or volcanic ash through low-grade regional metamorphism. Supplied in lots of 1 kilos, with an information label.
Specimens of Pegmatite collected from the East Coast of Scotland. This igneous rock is similar in composition to granite but with large crystals reaching up to metres across. Specimens are available in multiple sizes and comes in a white card tray with an information label.
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.
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.
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.
Specimens of Accretionary Lapilli Tuff collected from Longsleddle in Cumbria, UK. This igneous pyroclastic rock forms when material from volcanic activity ejects into the air. Specimens are available in multiple sizes and comes in a white card tray with an information label.
Specimens of Syenite, collected from Southern Norway. Syenite is a plutonic igneous rock, and its composition is almost entirely made of feldspar. Specimens come in lots of 1kg, in a heavy duty polythene bag. These specimens range from blue to dark green in colour. Specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Syenite thin sections for microscope study which are available to buy HERE.
Specimens of Banded Rhyolite collected from Glen Coe in Scotland. This variation of rhyolite shows the flow banding from the action of the lava which forms the rock. Specimens are available in multiple sizes and comes in a white card tray with an information label.
Specimens of Rhyolite Felsite collected from Fife in Scotland. This variation of rhyolite contains mostly quartz and feldspar giving the rock its pale pink colour. Specimens are available in multiple sizes and comes in a white card tray with an information label.
Specimens of Gabbro Big Feldspar collected from Carrock Fell in Cumbria, UK. This rock is similar in composition to gabbro but with very coarse minerals giving a speckled look. Specimens are available in multiple sizes and comes in a white card tray with an information label.
We also supply Gabbro Big Feldspar thin sections for microscope study which are available to buy HERE.
Syenite thin section slide. The thin sections show a dominant feldspar mass ( orthoclase ) with occurrences of hornblende, amphibole and clinopyroxene. Biotite mica may also be present however its occurrence is rare, The thin section is supplied in a protective card sleeve with a label, ideal for microscopy and educational purposes.
