Abstract

Kinichilite, a new mineral from the Kawazu mine, is hexagonal with a=9.419 Å, c=7.666 Å, space group P63 or P63m. The empirical formula derived from the chemical analysis is: (Fe2+1.13Mg0.47Zn0.43Mn2+0.17)Σ2.20(Te2.97Se0.03)Σ3.00 O9.00(H1.38Na0.22)Σ1.60·3.2H2O, corresponding to Fe2+ dominant analogue of zemannite.
It is dark brown in colour. Subadamantine luster and brown streak. No cleavage. Density (calc.) 3.96 g/cm3 from normalized empirical formula and Z=2.
