Microscope thin section slides of limestone breccia from India, showing large clasts of limestone cemented in a matrix. Breccia is formed when large angular fragments are cemented together in a matrix of smaller particles with a mineral cement. It is formed by mechanical weathering processes that create angular fragments, if fragments are eroded to become more rounded then the rock formed would be classed as a conglomerate. 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.

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.

Specimens of Breccia, collected from the Manifold Valley in Staffordshire. Breccia is a term that describes coarse grained sedimentary rocks, with large angular clasts, surrounded by a finer grained matrix. Calcrete binds the clasts in these specimens, forming on calcareous materials in response to climatic fluctuations in arid and semi-arid regions. These specimens are available in multiple sizes and come supplied in a white card tray with information label.

Specimens of Breccia, collected from Yorkshire. Breccia is a term that describes coarse grained sedimentary rocks, with large angular clasts, surrounded by a finer grained matrix. These specimens date to the Holocene period, approximately within the last 11ooo years. These specimens are available in multiple sizes and come supplied in a white card tray with information label.
