| Title | Aragonite on calcite |
|---|---|
| Description | Aragonite and calcite are both CaCO3. Here we see white aragonite popcorn on top of clearer calcite crystals. This specimen comes from an unknown cave. Samples like this are rarely collected today because collecting them damages natural cave beauty. This photo is about 4 cm across. |
