Clino-Zoisite
Clinozoisite is a complex calcium aluminium sorosilicate mineral with formula: Ca₂Al₃O. It forms a continuous solid solution series with epidote by substitution of iron(III) in the aluminium and is also called aluminium epidote.
Clino-Zoisite is found in numerous locations throughout South Africa, Zimbabwe, Namibia and Swaziland.
