PETROGRAPHIC THIN SECTION PREPARATION
We specialize in preparation of thin sections for petrographic study. We provide lab services for geoscientists in government and environmental agencies, university programs, concrete and material research and development departments.
- Standard thin section is a 30 µm-thick slice of rock, concrete, etc., mounted with epoxy onto a 26 × 47 mm glass slide. This type of thin section is best suited for routine petrography.
- Polished thin section which has a scratch-free, highly reflective surface. Polished thin sections can be used for electron microprobe or SEM analysis, or to identify by reflected-light petrography the various kinds of opaque, metallic minerals present in most rocks.
- Polished ore sections are thick, polished plates mounted on transparent resin or standard 27 × 46 mm slides for reflected-light microscopic analysis of opaque metallic minerals (ore minerals).
