Studies of rock fabrics, e.g. porosity and permeability; Studies of texture and age of bones/teeth; About How to Contact Specimen Types Specimen types can be split into four groups: Thin Sections (30µm) (+ cover glass) - for examination in transmitted light or electron microscope/probe; Polished Thin sections - for examination in transmitted ...
Thin section preparation begins with a visual inspection of the rock. A sample is then prepared, and, if necessary, water is extracted using low temperatures, time, or it's replaced with alcohol. …
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, …
A method of manually making thin sections is presented. Simple techniques for maintaining parallelism that avoids direct measurement is described in detail and a number of examples …
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. ... This is the step in which most thin sections go bad. The ...
Welcome to the micROCKScopic.ro project website containing a large thin-section collection of minerals and rocks under the petrographic microscope.. micROCKscopic.ro makes Optical Mineralogy and Petrology be easier to examine a thin section and to understand the characteristic properties of each mineral/rock without a petrographic microscope, which is known to be very …
A thin section is usually a rock, but may also be a soil, pottery, bone, or metal sample used in mineralogy and petrography. The material is cut with a diamond saw to turn it into an incredibly fine object mounted on a glass slide to study its …
A thin section of rock is prepared so mineralogists and petrologists can identify, study, and analyze the material more closely. This is known as thin section preparation. Using this method, you can classify minerals, identify problems in quarries or structures, examine mineral potential in geological environments, and identify the geographical source of archaeological artifacts.

With the stronger bond, failures are minimized, and both coarse and final grinding of the section can be hastened. Large 2- or 3~inch thin sections of rock as well as normal-size thin sections can be prepared on ordinary glass whose …
THIN SECTON PREPARATION PROCEDURE 1. PURPOSE Thm purpose of this procedure is to document the process for the preparation of thin sections from rock samples. Thin sections am …
Preparation of Rock Thin Sections for Limestone Samples. Limestone is a sedimentary rock comprised mainly of the minerals Calcite and Aragonite, which are distinct crystal structures of Calcium Carbonate (CaCO3). This rock type primarily consists of skeletal fragments from marine organisms such as coral and foraminifera, and constitutes ...
Thm purpose of this procedure is to document the process for the preparation of thin sections from rock samples. Thin sections am used for geological analysis on the microprobe, various microscopes, and for other geological analysis. 2. SCOPE This procedure covers any geologic thin sections prepared In ESS Division for the Yucca Mountain
If thin section making is such an "old technology," why do you think we continue to prepare and analyze thin sections in much the same way today? References. Holmes, Arthur (1923), Chapter VI. Preparation of thin sections. Petrographic methods and calculations, London, Thomas Murby & Co, Pt. 2, 231-249.

My first attempt at making rock thin sections by hand #1 Post by The QCC » Fri Mar 06, 2015 8:51 pm To grind or mot to grind. That is the question. I have been purchasing my mineral / rock thin sections for about $8.00 CDN per slide or $700.00 CDN /100. I know it is not cost effective to buy a lapping machine ($650.00 CDN) and make less than a ...
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 learned by perseverance and practice. SUMMARY …

The Rock and Thin Section Preparation Laboratory is operated by Mr. Pike Holman in the basement floor (Room 012) of Lindley Hall. The laboratory provides sample preparation services to students, faculty, researchers, and clients from the public and private sectors. ... Thin sections can be ordered in a standard size (55x65mm or 26x46mm") or ...
Most optical mineralogy today involves specially prepared thin sections (0.03-mm-thick specimens of minerals or rocks mounted on glass slides).Video 1 (linked in Box 5-2) explains how we make thin sections, and Figure 5.1, the opening figure in this chapter, shows an example. Figure 5.4 above shows a microscope view of a thin section that contains several minerals (biotite, …
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 …
A firm rock of mineral of which a thin section is to be made must first be sawed to obtaln a slice approximately 1/8 in. thick. This is then cemented to a numbered glass slide with Canada balsam, pressing the slice at an oblique angle against the glass slide to eliminate bubbles. The slice is then ground on a rotating lap using 1F silicon carbide and finally on a similar lap using # 600 ...
In recent years, the team has come up with a variety of materials and methods to make fluorescent rock-thin sections through repeated trials and achieved good results. View full-text.

Each numbered block of text ... section represents such a small portion of a rock you want to make sure it is representative. Things to mention in your hand specimen descriptions are ...
Some people love making thin sections because the process can be meditative, though not always quiet if you are using a rock saw! Others can find the process frustrating, especially the last step which requires patience to slowly approach the final required rock thickness without destroying the sample.
