Actinolite, Epidote, Albite, Axinite-(Fe)

Locality: New Melones Dam, Copperopolis, Calaveras Co., California, USA

A choice cabinet specimen of fibrous Actinolite measuring 10 X 12.5 cm. with individual fibers reaching 15 mm.
This very dense grouping of Actinolite fibers causes an undulating, chatoyant "wave" effect
when rotated in the hand.
The matrix consists of a thick plate of crystalline green Epidote with prismatic
crystals to 4 mm.
Minor Axinite-(Fe) and small, gemmy Albite crystals are also present.
