Selected rocks and minerals are ground and polished to a thickness of 20 – 30 ?m. The preparations are mounted with Canada balsam on slides of 45×30 mm. In order to identify forms, colours, refractions and fossil inclusions, the slides can be observed with any normal microscope in transmitting light. Additional information is obtained by using microscopes with polarized-light equipment.
