| CaCO3
- Weakly flourescent, sharp, clear to opaque white crystals. Most are etched. Fine grained calcite (associated with fine grained quartz and Fe carbonate) is pseudomorphic after aragonite. | |
| FeS2 - Late stage pyrite coats drusy quartz and calcite. Some pyrite appears to have precipitated along a common side of the earlier formed minerals. | |
| SiO2 - Flourescent banded chalcedony (blue, grey, brown, white). Quartz is also present as drusy (some light amethyst, some sceptered). Late stage drusy is gemmy and can be found coating earlier formed calcite crystals. |
