Tufa thin section slide. Tufa is a variety of limestone, formed by the precipitation of carbonate minerals from ambient temperature water bodies. This particular material is from the Flandrian epoch of the Quaternary Period and it was collected in Caerwys, North Wales. It forms in both fluvial and lacustrine environments but also subterranian passages ( dripstone, stalagmites & stalactites ). Geothermally heated hot springs sometimes produce similar (but less porous) carbonate deposits known as travertine. Tufas are commonly characterised by their macrobiological component however in our specimens there are no signs of biological remains. The thin section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip. Supplied in a protective card sleeve with a label, ideal for microscopy.

Travertine thin section slide. Travertine is a form of limestone deposited by mineral rich springs, especially hot springs. It is formed by the rapid precipitation of calcium carbonate, often at the margins of a hot spring or in a limestone caves.

Specimens of Tufa, collected from Caerys, North Wales. Tufa is a variety of limestone, which forms by the precipitation of carbonate minerals from ambient temperature water bodies. These specimens date to the Quaternary period, specifically, the Flandrian epoch. It forms in fluvial channels or lacustrine environments & subterranian passages (dripstone, stalagmites & stalactites). This rock specimen is a classic tufa, light in weight, spongy, and containing many plant, preserved in the rock. Specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Tufa thin sections for microscope study which are available to buy HERE.

Marble thin section microscope slide exhibiting and a high birefringence, twinning and an interlocking nature setting it apart from the sedimentary quartzite rocks which we also supply. The glass is 46 x 27 mm in size, supplied in a protective card sleeve with a label, ideal for microscopy, petrography & educational use.

Specimens of Limestone, collected from Derbyshire. Limestone is a common, well known sedimentary rock. It consists of the calcium-rich shells, bones, and skeletons of the fauna that dominated during that period. It was laid down approximately 350 million years ago in semi tropical seas and comes from the Dinantian epoch of the Lower Carboniferous. This rock is very pure, about 98% soluble in rainwater (over time) leaving only residual clay. Its uses include aggregate, building stone, the manufacture of cement, paper & calcium carbide. Available in various sizes, each piece comes supplied in a white card tray with information label.
We also supply Limestone thin sections for microscope study which are available to buy HERE.

Dolomite microscope slide with extreme birefringence in XPL and varied relief in PPL. Excellent to observe the nature of the minerals and interpret the history of the rock. The glass slide is 46 x 27 mm in size, suitable for enthusiasts, educational use and more, it will come in card sleeve with a label.

Specimens of Travertine, collected from Yorkshire,UK. Travertine is a type of limestone which forms by the rapid precipitation of calcium carbonate, often at the margins of a hot spring or in limestone caves. It often has a fibrous or concentric banded appearance. Travertine is typically white or buff in colour, but can range through to orange and brown occasionally. It tends to be much denser and more compact than Tufa, and has notable uses as a decorative stone. Specimens are available in multiple sizes and come supplied in a white card tray with an information label.
We also supply Travertine thin sections for microscope study which are available to buy HERE.

Pumice thin section slide exhibiting the highly vesicular nature of this extrusive igneous rock. Pumice lavas tend to be silicic or felsic which are highly viscous thus do not allow the gas bubbles to escape efficiently.This material was collected from the Lipari islands of Italy.

Old red sandstone microscope slide exhibiting the well sorted nature of this particular sediment. Excellent to observe the nature of the minerals and interpret the history of the rock. The glass slide is 46 x 27 mm in size, suitable for enthusiasts, educational use and more, it will come in card sleeve with a label.

Amygdaloidal basalt thin section slide exhibiting amygdaloids of varying sizes within a fine grained basaltic ground mass. This particular material was collected from the Isle of Skye, Scotland. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip. Supplied in a protective card sleeve with a label, ideal for microscopy.

Purbeck Limestone thin section slide exhibiting densely pack shells of varying fauna. This rock is particularly interesting in thin section; numerous shells from varying organisms such as bivalves and gastropods along with numerous signs of mineral replacement and dissolution offers an opportunity to interpret the complex diagenetic history of the rock.

Hornblende Gneiss thin section slide exhibiting an abundance of the mafic mineral hornblende, accompanied by less abundant biotite mica, quartz and feldspar. This material was collected by staff from Southern Norway. Each section is made to 30 microns thickness and the glass is 46 x 27 mm in size, ideal for microscopy and educational purposes.

Big feldspar gabbro thin section exhibiting exactly what its name describes, feldspar crystals much larger than those present in the ordinary gabbro which we supply. Characteristic twinning in the plagioclase and the bright colours of the pyroxene make for an attractive thin section, perfect for educational use.

A thin section of mylonite which was collected from the metamorphic region of Lom, Central Norway. Mylonite is a fine-grained, compact rock produced by dynamic recrystallisation of the constituent minerals resulting in a reduction of the grain size of the rock.

Lignite thin section slide. Lignite coal and indeed all other varieties of coal are classed as organic sedimentary rocks. It has a high carbon content 25 – 35% & a moisture content up to 66%. The high volatile component of lignite is clearly reflected in the thin section view, particularly when compared with those of higher grade coals.

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.

Cordierite Hornfels thin section microscope slide exhibiting a dark colour and a characteristic none crystalline form. Fine grains fit together like the fragments of a mosaic, this is often referred to as rough pavement or pavement structure. Larger crystals of cordierite can be seen scattered throughout the fine matrix.
