Thin sections are used to identify minerals, their structural aspects (cleavage, fractures, mineral zoning) and rock textures that indicate the mode of formation of the rock. A thin section is a sample polished on two sides and ground to ~30 m thickness; the thin section is typically glued to a microscope slide.
Thin sections are just very thin slices cut from a rock that can then be viewed under an optical microscope. When you see sections like this that have all sorts of beautiful colours, it's because the microscope is using what is called cross polarized light.

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.
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.
Alibaba offers 33 rock thin section products. About 24% of these are other educational supplies. A wide variety of rock thin section options are available to you, such as free samples.
The thin section is then viewed with a polarizing microscope. The view in plane polarized light is the same as looking at the thin section through a pair of sunglasses. If you place a second pair of sunglasses behind the thin section and hold it perpendicular to the first pair, then you are viewing the thin section through cross polarized light.

How to make rock thin sections, without much equipment! What you need: • petrographic glass slides and cover slips. • Epoxy. • small diamond saw (a tile saw will do fine). • lap for grinding -- a 10 to 12" square of plate glass will work if you don't have a wheel lap.
One side of the rock chip is flattened (by sawing and grinding) and is glued to a glass slide, usually with epoxy. The rock chip is trimmed with a special rock saw, and then thinned on a grinder. This produces a thin slab of rock glued to the glass, which is thinned to 30 micrometers on a polishing wheel. Once the section is 30 micrometers .
Aug 21, 1973 · Study of the thin rock section under a polarizing microscope enables color identification of the mineral constituency of the rock. The cutting of thin rock sections for such analysis requires extreme precision as variance from a desired thickness will render color indication of the rock constituents extremely difficult.
