Making Petrographic Thin Sections By Machine Mod 4 1. it is generally best to prepare friable or porous samples by first cutting them into pieces about the size of a thin section chip (about 3.5 x 2.5 x 1.5 cm). most friable samples contain excess water in between grains, adsorbed on clays, in zeolites, and elsewhere. The general procedure for creating thin sections has remained nearly the same since the modern version was created nearly 200 years ago. in this section, we review examples of modern thin section making procedures.
Making Petrographic Thin Sections Guide The following is a description of how to make thin sections using the facilities in the union college geology department. thin section facilities at other schools will probably have somewhat different equipment, supplies, and rules, but these instructions will be largely correct in anywhere. Put the section rock side down into the slurry and, while pressing on it with your fingers, move the section in circles or figure 8's to grind away the thickest parts. A crucial aspect of this analysis is the preparation of thin sections, which involves transforming a rock sample into a translucent slice suitable for microscopic examination. this article delves into the techniques and methodologies involved in preparing high quality petrographic thin sections. Indispensible prerequisites for the success of investigations using transmitted or reflected light microscopy are good thin sections or polished sections.

Thin section facilities at other schools will probably have somewhat different equipment, supplies, and rules, but these instructions will be largely correct in anywhere. making thin sections is both an art and a science. The experiment involves cutting rock samples into thin sections, mounting them on microscope slides, and examining the samples under a petrographic microscope to identify rock types and their mineral constituents. A thin sliver of rock is cut from the sample with a diamond saw and ground optically flat. it is then mounted on a glass slide and then ground smooth using progressively finer abrasive grit until the sample is only 30 μm thick. The petrothin thin section machine is a versatile, 8in [203mm] tabletop cutter and grinder, perfectly suited for crafting thin sections of a wide range of materials, including bone, ceramics, concrete, petrographic samples, and more.
