Stone notes
- Carbonates & evaporites: Limestone and related sedimentary rocks are common in many arid coastal settings; salt and other evaporite minerals are also regionally important.
- Basement rocks: Older metamorphic and igneous rocks occur in upland areas and can host small-scale mineralization.
- Collecting context: Many specimens encountered in trade are labeled broadly by region; confirm locality and matrix when possible.
