Thin section preparation for geology.
Thin sections used for petrological and mineralogical observations are made in different sizes and using different techniques for curing, polishing and staining. Our products are made by experienced cutters, using only the finest grinding powders, adhesives, and diamonds. In addition, mineralogical preparations can sink in aluminum rings or ankle carry rocks. Preparations are dedicated to the study of mineralogical, petrological or fluid inclusion. The waiting period is dependent on the quantity ordered preparations. We invite you to cooperation.
We also provide petrographic and mineralogical analysis made preparations. We make observations using a high-quality optical microscope in polarized light. For petrological and mineralogical descriptions we include photographic documentation. We also have excellent access to analytical equipment in the field of X-ray microprobe analysis (EPMA and EDS), the qualitative and quantitative analysis we include photographic documentation made in BSE. We invite you to cooperation.
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 colour 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 colour 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.
