Thin Sections (Petrography)
Back to Geology · Back to Methods
In plain terms
A thin section is a rock slice so thin that light passes through—turning minerals into readable patterns.
Key takeaways
- Confirms minerals that are ambiguous in hand sample.
- Texture shows growth history and deformation.
- Polarized light reveals optical properties.
- Common in petrology and provenance studies.
- Pairs well with geochemistry for robust interpretation.
