| Title | Prehnite |
|---|---|
| Description | The green crystals here are prehnite. Prehnite is a hydrous, calcium-aluminum-silicate mineral which is commonly found in cavities and “pillows” and along fractures of basalt and diabase rock. It is often found in association with quartz, datolite, apophyllite, and various minerals of the zeolite group. It is a phyllosilicate mineral having interest to mineral collectors, but presently no economic uses. This sample is roughly 8 mm in diameter. |
