Rock Thin Section Preparation for Limestone Limestone is a sedimentary rock composed largely of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO3). Many limestones are composed from skeletal fragments of marine organisms such as coral or foraminifera.

The preparation of thin sections represents a fundamental step required for the study of minerals and rocks in geoscience. As such, the majority of the equipment in the Thin Section Lab is available for use by properly trained CSM students. Undergraduate and graduate students also work in the lab and assist in the production of thin sections.

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.

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 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.

A thin section is a 30 µm (= 0.03 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.

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. We have sufficient equipment so that the art aspects are relatively minor, but every rock is different and technique can best be

In optical mineralogy and petrography, a thin section (or petrographic thin section) is a laboratory preparation of a rock, mineral, soil, pottery, bones, or 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.

A slice of rock was affixed to a microscope slide and then ground so thin that light could be transmitted through mineral grains that otherwise appeared opaque. The position of adjoining grains was not disturbed, thus permitting analysis of rock texture. Thin section petrography became the standard method of rock study.
