The PetroThin Thin Section Machine is a precise easy-to-use precision thin section cutting machine for re-sectioning and thinning a wide variety of samples, such as rocks and minerals, ceramics, concrete, bone, and teeth for performing materials characterization.
The tests presented in this study were carried out with a 17″ constant cross-section disc cutter with a tip width of 15.8 mm, penetration depths ranging from 1.27 to 6.35 mm (1/20″ to 1/4″) and a cutting speed of 1 m/s.
A cast thin-section rock sample in this case is pigmented by a coloured (e.g., ... Similarly, the unrealistically small rock matrix areas removed by applying T 2 are shown in Fig. 11 c. The proportion of removed "rock matrix" is 0.30%. ... A rock sample from an outcrop or a drill core is cut into a block of size 25 mm × 25 mm × 5 mm. The ...
The technique of using a microtome to cut thin or ultrathin sections of tissues embedded in a supporting substance. The microtome is an instrument that hold a steel, glass or diamond knife in...
They mounted that slice to a glass slide, and then they ground down the other face of the slice until light could pass through the remaining rock. This is called a thin section. Put it underneath a microscope, and here's what it looks like: Apollo 11 sample 10062 thin section in ordinary transmitted light Image: NASA / JSC
1) Cut the rock into a thick rectangular prism, or plaquette, with more or less parallel front and back faces and a thickness of 2 cm or more. 2) Polish one face of the plaquette. If the face is very rough or uneven, start with 120 grit, but if not use ca. 220 grit, change to ca. 400 grit, and finish with 600 grit on a glass plate.
For example, considering the extinction features of rock thin section itself, Hu et al. proposed a sequence image analysis system for rock thin sections based on continuous extinction feature ...
The production of thin sections is a multistep process which requires highly specialized equipment. Combining the equipment, the consumables, the work process, and …
The saw microtome cuts materials slowly using a rotating, diamond-coated saw. You can not produce very thin sections with a saw microtome, but, as long as the blade is in excellent condition, you should be able to cut sections that are 20 µm or more in thickness. 7. Cryostat Blade.
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 …
The best hammer for rockhounding is the Geologist's hammer, while a good chisel should always have a carbide tip, it all depends on what type of rock you want to …
Turn on the thin section machine. 2. While carefully but firmly holding a glass slide, touch one corner of the slide to the flat. surface of the cup wheel for a second or so, just enough to grind off a bit of the corner. This. mark will let you orient the slide properly on …
The most widely used method for mineral type classification from a rock thin section is done by the observation of optical properties of a mineral in a polarized microscope rotation stage....
1. Introduction. The polarizing microscopic thin sections of rocks reflect the mineral composition, structural characteristics, grain size, and other characteristics providing geological information for subsequent exploration and development, which are crucial in petroleum geology, exploration, and mining research on account of this is a kind of …
Analyses of rock failure mechanisms beneath disc cutters are presented. Full-scale cutting tests are conducted to assess the global energy input in comparison with rock chips and excavated volume. Small-scale cutting tests are subsequently used for macro- and microscopic analyses of rupture modes and crack propagation. A high …
The lab recently acquired a Pelcon Automatic Thin Section machine. This machine allows one operator to create 10 to 30 thin sections per day while maintaining a high level of quality. The thin sections maintain a consistent and even thickness while minimizing plucking and damage. ... Rock Cutting: $5.00/cut. Polishing: $15.00/face ...

The Pelcon Automatic Thin Section Machine is designed for the production of thin section specimens of concrete, rocks, sand or aggregate samples to be used for optical …
A thin section is a pre-prepared 30 µm (= 0.03 mm) +/- 2µm thin slice of solid material, having at least one glass slide glued to one of its sides with epoxy. Placed between two polarizing filters at the right angle, the in-situ minerals' different optical properties alter the colour and intensity of the reflected light.
This study covered a total of 13 rock types (andesite, granite, peridotite, gabbro, rhyolite, tuff, diorite, phonolite, basalt, syenite, limestone, sandstone, and schist) of 92 representative rock samples in igneous, sedimentary, and metamorphic categories.
2) The thin section cut must be marked (for example 28 x 48 mm) including the focus on one of the two cutting surfaces (front or back) of the specimen . 3) Formatting the sample.
Cutting Rocks with the Rock Saw Rocks need to be cut to remove weathering surfaces, to cut thin sections, and to select portions for pulverizing. Wear an apron, goggles and ear protection.
