Overview of Services

Basic info for Thin Section, Core and Sample Preparation (Location 15-00-12).

This lab operated to produce Thin Section, Core and Sample Preparation. Most of sample are from rock but also accept sample e.g.: Steel, Composite etc.

This lab consists of 14 major equipment and numbers of consumable items.

1. GEOCUT
2. MICRACUT 175
3. FORCIPOL 300-IV & FORCIMAT-TS
4. BUEHLER PETROTHIN
5. VACUUM CHAMBER (FOR FRAGILE MATERIAL E.G: SANDSTONE) (2 unit)
6. GSP210/250CORE TRIMMER/CUT-OFF MACHINE (2 unit)
7. C350 SPECIMEN CUTTING MACHINE (450 mm BLADE) (FOR LARGE SAMPLE) (2 unit)
8. NALIK CORING MACHINE
9. ROTAP SEIVE SHACKER RX-29
10. COREX S25-fas CORING MACHINE
11. WDM WET AND DRY CORING MACHINE

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 then mounted on a glass slide and then ground smooth using progressively finer abrasive grit until the sample is only 30 μm thick. The method involved using the Michel-Lévy interference color chart. Typically, quartz is used as the gauge to determine thickness as it is one of the most abundant minerals.

When placed between two polarizing filters set at right angles to each other, the optical properties of the minerals in the thin section alter the color and intensity of the light as seen by the viewer. As different minerals have different optical properties, most rock forming minerals can be easily identified. Plagioclase for example is a clear mineral with multiple parallel twinning planes. The large blue-green minerals are clinopyroxene with some exsolution of orthopyroxene.

List of consumable
1. Diamond sheet polisher
2. Carbide powder
3. Resin (for fragile rock)
4. Hardener (for fragile rock)
5. Dye (for porosity measurement)

Coring Operation
Coring is a process where to produce cylinder sample for testing. We offer size range from 1-inch to 3-inch size in diameter and maximum length 4-inch depend on sample size. 
Example of testing for cylinder sample are:
1. Porosity and Permeability test
2. Compression test
3. Triaxial test
4. Tensile test
5. P and S wave measurement
6. Point load test and many more

Sample Preparation
For sample preparation, specification of sample is referring to equipment user use for analysis or testing. For example, SEM (normally this instrument)
