THIN SECTIONS Archives - Geology Superstore

Introducing our range of Geological Thin Sections. Each of these microscope slides have been produced from our very own stock of rocks and minerals, ensuring their authenticity. Each slide is made to a thickness of 30 microns and measures 46 x 27 mm in size. Every thin section also features a glass cover slip. They are suitable for use with petrological microscopes in both plain and cross polarised light (PPL and XPL).

Additionally, we also possess the ability to create thin sections for use with a scanning electron microscope (SEM). These slides are highly polished and feature no glass cover slip. Since this is a custom service, it is available for bulk orders only. Please contact us via email or through our Contact Us page if this is something you are interested in.

Custom Geological Thin Sections
For bulk purchases (in the region of 20+ slides), we possess the ability to have geological thin sections custom made to meet your requirements. This isn’t limited to just our standard polarising microscope slides. We can have samples prepared for a range of different analysis methods. This includes:
- EMPA (Electron Microprobe Analysis)
- EBSD (Electron Backscatter Diffraction)
- SEM (Scanning Electron Microscope)
- Fluid Inclusion Wafers
All microscope slides are made from our own stock of geological specimens that we keep at our premises in Bolton. This ensures that all of our thin sections are genuine, with each one being traceable to the locality it was collected from.

We recently fulfilled an order for 24 custom thin sections and corresponding hand specimens for educational use. These sections were highly polished, made with no glass cover slip, and to be used by a college for SEM and EDS (Energy Dispersive X-Ray Spectroscopy) analysis.

Should you have any questions about custom thin sections, then don’t hesitate to contact us via email info@geologysuperstore.com. Alternatively, you can fill in our contact form by clicking
