|
| Species: | Epidote |
| Formula: | (CaCa)(AlAlFe3+)O[Si2O7][SiO4](OH) |
| Comments: | Single crystals are found loose in pocket clay and as inclusions within Quartz crystals. Epidote crystals from the Valley Springs area can be quite similar in habit to those from the New Melones Reservoir to the south. Less commonly found in pockets are unusual, dense clusters of unterminated crystals associated with Quartz. The terminations of these groups being found loose in the pocket clays. |
