    How to make rock thin sections, without much equipment

    Begin by breaking your rock sample into a size small enough to cut on your diamond saw. Then, holding it tightly (use a sliding brace if you have it), cut the rock into a rectangular block with dimensions smaller than a slide. If you are just learning

    coverslip or a ruler, mark off a coverslip-size area on the rock slab that you want to see in thin section. Several chips can be marked at once on a big slab this way. Remember that the trim saw blade makes cuts about 1.5 mm thick (about 1/16 ). 2. Make sure the small trim saw has enough coolant in its tank. Turn on the saw and make sure

    rock can be made into a thin section, unless it is very soluble, friable, or poorly cemented. Those must be treated in advance by impregnating them with epoxy or another hardener. From your rock sample, break off a piece a few inches in size, using a rock hammer, ball-peen hammer, or mason (brick) hammer -- not a nail hammer! With the diamond

    Cut several strips from the thickest stock about 1/4 to 3/8 wide and the full length of at two times the width of the slide. Take one of the thickest strips and a blank or scrap microscope slide and wrap the piece of shim stock around the short dimension of the slide

    Rock Thin Sections (Petrographic 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

    This is a thin section of a rock largely made of crystals of plagioclase feldspar and pyroxene. Small amounts of amphibole and opaque iron oxides also occur. It shows a porphyritic texture. Images in this resource could be used to practise microscope drawing skills

    why do geologists use thin sections of rocks

    Nov 29, 2021 How do you make a rock thin section? This process is a simple one: Make sure the section is clean and free of grit or dirt. Place it on the hot plate. Mix up a small batch of epoxy and hardener. Place a small drop of epoxy on the section. Drop a cover slip on the drop. Move it around to expel bubbles and fully coat the section. Let it cure

    Dry the thin section on the hot plate for 5 minutes. Place a thin line of epoxy down the center of the thin section. Make sure to use a small amount of epoxy. Take a single cover slip (careful, they often stick together) and place onto thin section. Use a pencil eraser to gently slide around and remove bubbles

    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

The rocks were also just the right size for a first attempt. See photo 1. Making thin section slides, according to the articles on the web, requires patience and a very flat work surface

    Aug 04, 2021 Rock thin-sections are the essential tools for studying geology at K12 or college-level classrooms. They can change boring lectures about rocks to fascinating practices. However, due to the difficulties of preparation, there are a few attempts to use rock thin sections as teaching tools in K12 classrooms

    Jul 26, 2017 Thin sections are slices of rock, mounted on glass, that are ground thin enough to transmit light. This allows microscopic examination of crystals, grains, fossils, and rock fabrics. Thin sections are of special value to three groups of paleontologists: 1) taxonomists studying groups whose classification rests on internal features or skeletal

    The first stage in the thin-section preparation is cutting the sample to a suitable size for processing. This small section must first be removed from a larger rock sample. The GTS1 Thin Section Cut-off and Trim Saw is ideal for geological applications and allowing users to cut hard or soft rocks, concretes or cement, with equally high efficiency

    Nov 21, 2018 The general procedure for creating thin sections has remained nearly the same since the modern version was created nearly 200 years ago. In this module, we review two examples of modern thin section making procedures. If you have read the history of thin section preparation (section 2.3), you should be already familiar with most of the process
