- Large titanite euhedra are abundant along with apatite and zircon, with allanite and epidote less so.
- Most such specimens are partially coated with a druse of calcite, epidote, and small, clear needle quartz crystals.
- Fine lustrous epidote crystals to 15 cm long have been collected at the Julie claim near Hawthorne, Mineral County, Nevada.

adjective

Origin

Early 19th century: from French épidote, from Greek epididonai 'give additionally' (because of the length of the crystals).
