grinding, the thin rock section beneath a bubble is unsupported and may disintegrate. Removal of bubbles from the resin in a vacuum chamber is a slow, usually incomplete process requiring a fairly strong house vacuum or a separate vacuum pump and chamber.
06/04/2020 · The Earth Planetary Sciences' Rock Preparation Facility is fully equipped to aid researchers in petrographic section making, rock crushing, sample sieving, and mineral separation, with a fulltime technical staff member to oversee the functioning of this facility. The facility includes equipment for: thin sectioning (slab saws, rollingtable trim saws, thinsection cutoff saw and grinder ...
A thin section is a 30 µm (= 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. The epoxy ideally has an index of refraction of, although our epoxy is slightly higher, perhaps

The Department maintains extensive facilities for sample preparation producing thin sections, polished sections, rock powders and mineral separates. There are several saws for making cuts at different scales. There are automatic and manual grinders and polishers using diamond, SiC, alumina and colloidal silica. A variety of epoxies and temporary adhesives are available for

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 ground optically flat. It is ...

3. Investigate grinding and polishing of rock to thin section finish quality 4. Investigate epoxy and backing material application. Surface roughness: A substitute method for the quality control of thin sections could be done with profilometry, the measurement of surface roughness at very fine scales. To test this new method, profilometry
· Detailed Description. Photomicrograph of gabbroic inclusion in Ogres Brow basaltic andesite. A rock thin section is created by gluing a small piece of rock onto a glass slide, then grinding it down to a thickness of 30 microns (the average human hair is about 100 microns in diameter) so that light shines through it when examined under the microscope.
02/05/2018 · See the section on abrasion and appliion at the end of this book for more information on that. To make good sidewalls for your flat lap, either build wooden edges all the way around the wheel, above the level of the wheel face, or cut the bottom out of a plastic pan or box, leaving enough of the bottom around the edges to use as boltdown. Set the pan or box over the wheel, then screw down ...
