Chalk thin section microscope slide composed of the debris of calcareous planktonic algae i.e. minute calcite shells known as Coccoliths which detach from micro-organisms known as Coccolithophores. Chalk is a soft, white, porous sedimentary carbonate rock; a form of micritic limestone. It forms under relatively deep, low energy conditions where the gradual accumulation of these calcareous organisms is permitted. These thin sections exhibit abundant coccolithophores within an even finer micritic matrix. This material is Cretaceous in age and it came from Yorkshire. The glass is 46 x 27 mm in size, supplied in a protective card sleeve with a label, ideal for microscopy, petrology & educational use.

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.

Oolitic limestone thin section slide exhibiting textbook ooid grains, some with a clear nucleus and concentric calcareous layers. These microscope slides supplement the hand specimens nicely and allow for a more detailed view of the ooid grains and an opportunity to intepret the diagenetic history of the rock.

Shelly limestone thin section slide exhibiting the calcareous remains of various fauna. These thin sections complement the hand specimens nicely and allow for more precise paleoenvironmental interpretations to made. The thin section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip

Specimens of Chalk, collected from Yorkshire, in the UK. Chalk is a soft, white, porous sedimentary carbonate rock and form of limestone. It forms in reasonably deep marine conditions, by the gradual accumulation of minute calcite plates, known as coccoliths, which shed from micro-organisms called coccolithophores. Additionally, it is not uncommon to find flint or chert nodules embedded in chalk. These specimens are Cretaceous in age, available in multiple sizes, and supplied in a white card tray with information label.
We also supply Chalk thin sections for microscope study which are available to buy HERE.

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.

Stunning peridotite thin section exhibiting the bright and beautiful colours of olivine and pyroxene punctuated by relatively abundant plagioclase. Peridotite is a dense, coarse grained, ultramafic igneous rock consisting largely of olivine and pyroxene.

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.

Torridonian sandstone thin section slide exhibiting a fine grained arenaceous nature. The Torridonian Sandstones date from the Pre-Cambrian & are amongst the oldest rocks to be found in the UK. The section is made to 30 microns thickness and the glass is 46 x 27 mm in size with a cover slip.

Diorite thin section slide. Diorite is a grey to dark-grey intermediate intrusive igneous rock composed principally of plagioclase feldspar (typically andesine), biotite mica, hornblende, and/or pyroxene. This particular material was collected in Cumbria.

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.

Rare eclogite thin section slides cut from our Norwegian eclogite hand specimens. Eclogite is a rare rock, composed of mainly two minerals, reddish-brown garnets and Omphacite (green pyroxene), our thin sections exhibit this clearly.

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.
