Thin Section Laboratory
The Thin Section Laboratory, located in the Department of Geology and Geological Engineering, provides sample preparation services for students, faculty, and other researchers at CSM, as well as federal agencies and industry clients. Outfitted with a host of slab saws, trim saws, grinders, epoxy impregnation stations, lapping machines, and polishing machines, the lab is equipped to produce a wide variety of thin sections and related mounts for geoscience investigation. The price sheet below lists our current capabilities.
The preparation of thin sections represents a fundamental step required for the study of minerals and rocks in geoscience. As such, the majority of the equipment in the Thin Section Lab is available for use by properly trained CSM students. Undergraduate and graduate students also work in the lab and assist in the production of thin sections.
Equipped with Logitech semi-automated lapping and polishing machines, the Thin Section Lab is able to hold roughly a one-micron flatness tolerance during the critical phases of thin section preparation. Our production methods result in precise target sample thickness and the ability to directly measure sample thickness throughout the production process. Our thorough billet preparation techniques ensure excellent mineral retention, and multi-step diamond polishing yields a superb polish.
