Epidote - Clinozoisite

Alchuri, Shigar Valley, Gilgit-Baltistan, Pakistan

Reference: 1935

Exceptional epidote/clinozosite specimen showing classic faden growth with a length of 55mm yet a thickness of only 5-6mm. The crystal is classic olive green with a high level of transparency. Some sites offer Alchuri material as clinozoisite some as epidote - most are probably somewhere between but i haven't had this one tested.

Formulas: Epidote {Ca₂}{Al₂Fe³⁺}(Si₂O₇)(SiO₄)O(OH); Clinozoisite {Ca₂}{Al₃}(Si₂O₇)(SiO₄)O(OH)
