    www.mindat.org/min-3989.html Chemically similar to mountainite, hydroxyapophyllite-(K), shlykovite, rhodesite, and cryptophyllite. The difference from tinaksite is in (1) greater lattice constants (mainly the parameter b), (2) longer distances, (3) longer M1-M3 and O20-O2 bonds, and (4) more distorted M1 polyhedron.Contains significant admixture of Fe 3+.

  • Tinaksite - Wikipedia

    en.wikipedia.org/wiki/Tinaksite Tinaksite (K 2 Na(Ca,Mn 2+) 2 Ti[O|Si 7 O 18 (OH)]) is a mineral found in northern Russia. Tinaksite can be grayish-white, yellowish, orange, or brown, and it is often found in charoite. Its name is derived from its composition: titanium (Ti), sodium (Na) potassium (K) and silicon (Si).International Mineralogical Association first recognized tinaksite as a mineral in 1965.
