  • Rocks in thin section

    Thin section 6. This video shows a thin section of a rock made of calcite and which is largely composed of non-skeletal grains. The properties of the main rock-forming minerals as seen under a polarising light microscope are described. Images in this resource could be used to practise microscope drawing skills. .

  • Thin section Introduction

    Rock specimens are often friable and brittle by nature therefore thin section preparation requires meticulous, reliable slabbing, grinding, lapping and polishing machines. thin section samples: Typical rectangular thin sections are 26 mm x 46 mm, although Vinci equipment permits size customization.

  • Thin section preparation

    In optical mineralogy and petrography, a thin section is a laboratory preparation of a rock, mineral, soil, pottery, bones, even metal sample for use with a polarizing petrographic microscope, electron microscope and electron microprobe. A thin sliver of rock is cut from the sample with a diamond saw and ground optically flat.

  • Petrographic thin sections for sale

    Thin-sections are carefully prepared glass slides suitable for mineralogical and petrology studies when viewed through a microscope. They are thin slices that have been carefully ground down and polished so thinly that light can pass through the mineral structures..

  • Igneous minerals in thin section

    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". Cross-polarized light, field width is 6 mm. 4.7.84G

  • General : Rock thin sections for polarising microscope

     · A good way to start is to get a classic British petrology text such as Harker (Petrology for Students) or more recent Nockolds, Knox and Chinner (Petrology) and then seek out the well-described rocks for your own thin sections. .e.g Harker describes and illustrates dolerites from Fair Head, Antrim.

  • Petrography

    Thin section petrography became the standard method of rock study. Since textural details contribute greatly to knowledge of the sequence of crystallization of the various mineral constituents in a rock, petrography progressed into petrogenesis and ultimately into petrology.

  • PREPARATION OF ROCK THIN SECTIONS* CoNrrxrs Abstract …

    PREPARATION OF ROCK THIN SECTIONS 1185 describes the procedures involved in making thin sections of ordinary, firm, non-friable materials as well as clays, coals, gypsum, water-soluble minerals, and minerals decomposed by water. The preparation of thin sections, which was described by Sorby (1882)'' was well developed by 1860.

  • How to make rock thin sections, without much equipment

    A hard, quartz-rich rock like granite or gneiss will take longer than a softer sedimentary or metamorphic rock. I mostly make thin sections of basalt, which is the dark gray type of lava. It is fine-grained with little or no quartz, so basalt grinds down quickly and evenly. To finish, cement a cover slip onto the rock, being careful to once again
