The Petrographic Thin-sectioning Lab offers a well-established service for the production of thin-section microscope slides. We can produce large 5 x 7 cm or small 2.5 x 4 cm thin sections of around 30 µm in thickness. We also make polished thin sections, which are used primarily in the observation of microstructures in reflected light.
Thin sections facilitate microscopic study under bright field or polarized transmitted light to determine the composition, textural and/or structural relationship of minerals in rock, unlithified sediment, sediment or concrete cores, archaeological material and ceramics. Samples, if unlithified, are dried, impregnated with resin and then processed into thin sections for the client.
Here is what a recent customer said about our service: “Again thank you for the thin sections. Not only were you fast, but you did a beautiful job. The sections are clearly labeled with a sticker, as opposed to being etched into the slide, thereby making them easier to read. Moreover, the rock chips and cut surfaces serve as nice “maps” for locating that part of the rock from which the section was cut. A beautiful job!!!” (August, 2009).
- Descriptions and interpretations of thin sections are also available. A sample report is provided here.
