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.

Textbook desert sandstone microscope thin section ideal for educational use.These thin sections exhibit well rounded quartz clasts as you would expect from an aeolian transported sediment. 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.

Kimmeridge clay thin section slide exhibiting the incredibly fine grained nature of this rock. Despite being so fine, individual clay grade minerals can be identified along with organics arranged in an obvious orientation. The slides are 30 microns thick and measure 46 x 27 mm in size and have a cover slip of the section along with a protective cardboard sleeve.

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.

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.

Portland Limestone thin section slide exhibiting micro oolites. Portland stone formed in sub-tropical seas where wave action resulted in the formation of micro oolites during the Tithonian stage of the Upper Jurassic.

Red marl thin section slide taken from Lower Triassic strata belonging to the Mercia Mudstone Group, formerly known as the Keuper Marls. Marl describes rock which is a calcium carbonate rich i.e. 35% – 65% CaCO3 with the remainder being clay with varying amounts of silt

Rock gypsum thin section slide exhibiting a range of textbook gypsum petrographic features. The slides are 30 microns thick and measure 46 x 27 mm in size and have a cover slip of the section along with a protective cardboard sleeve; perfect for educational use.

Shale microscope slide showing thin black lenses of organic matter (in XPL view) which fell from suspension in very low energy environments. 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.

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.
