About TinaksiteHide

Formula:
K2Na(Ca,Mn2+)2Ti[O|Si7O18(OH)]
Colour:
Yellowish, grayish-white
Lustre:
Vitreous
Hardness:
6
Crystal System:
Triclinic
Name:
The name reflects its composition: titanium (Ti), sodium (Na) potassium (K) and silicon (Si).
Isostructural with:
Tokkoite
The K analogue of senkevichite. Chemically somewhat similar to faizievite and odintsovite. When compared to tokkoite, it has smaller lattice constants (mainly the parameter b), shorter distances, shorter M1-M3 and O20-O2 bonds, and less distorted M1 polyhedron. There is some Fe3+ in the structure.
