Grinding of rock thin section

Jun 01, 2013 The Grinding Rocks Into Thin Sections (GRITS) system consisted of three stations. These were a grinding and polishing station, the quality control station, and the control station (laptop with control software). The grinding and polishing was done by a dual plunge wheel design, whereby the inner wheel had abrasive material suitable for material

    A thin section is a 30 m (= 0.03 mm) thick slice of rock attached to a glass slide with epoxy. Typical thin section slides are 26 mm x 46 mm, although larger ones can be produced. They are generally covered by another glass slide, a cover slip also attached to the rock with epoxy

    Damage produced during thin section grinding causes speckles of light in the biotite, where the crystal lattice has been deformed. This means that biotite in standard thin sections rarely goes completely extinct. This is called incomplete extinction or sometimes birds eye maple extinction .
