Simple Field Kit (Geology)
Back to Geology · Back to Minerals & Identification
In plain terms
A field kit helps you make repeatable observations—so your ID isn’t just a guess.
Recommended items
- 10× hand lens for grains and crystal faces
- Streak plate (unglazed porcelain)
- Small magnet for magnetism checks
- Hardness picks or common substitutes (coin, steel, glass)
- Dilute acid (handled safely) for carbonate reaction
- Notebook + pencil (write even when wet)
- Sample bags + labels for context and chain-of-custody
Key takeaways
- Context notes are as important as the sample.
- Use tests to rule out lookalikes.
- Label immediately—don’t trust memory.
- Handle acids and sharp tools carefully.
- Confirm important IDs with references or lab methods.
