Crinoidal Limestone thin section slide exhibiting a cross sectional view of crinoid stems and ossicles held within a calcite cement. Not all of the intricate detail has been preserved in the crinoids but this offers an opportunity to interpret the diagenetic history of the rock by analysing the nature, shape and relationship of the minerals present. This crinoidal limestone from Derbyshire was laid down in a shallow tropical sea around 300 million years ago in the Carboniferous. The 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.

Magnesian Limestone thin section microscope slide. This material belongs to the Zechstein Formation; a highly studied sedimentary formation which was laid down in the epeiric Zechstein Sea during the Mid to Late Permian Period. This material was sourced around Tadcaster in North Yorkshire and was deposited when the UK was situated at an equatorial latitude.

A small hand sample of fossil limestone containing numerous small Scyphocrinites crinoid stem fragments. Crinoids are fossilised sea lilies, these particular sample come from South Morocco. Often the stems are only preserved in fragments as can be seen. Samples measure approx in 3″ size and come in a small card tray with a label.

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 quartz clasts are visible but these have recrystallised to form a fine, interlocking mosaic of quartz within the original grain cast.

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.

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.

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.
