About TinticiteHide

Formula:
Fe3+3(PO4)2(OH)3 · 3H2O
Colour:
Creamy white with yellowish or brownish tint, bright ocher-yellow
Lustre:
Dull
Hardness:
Specific Gravity:
2.8 - 2.94
Crystal System:
Triclinic
Name:
Named after its discovery locality, a cave near the Tintic Standard Mine, East Tintic District, Dividend, Utah, USA.
Isostructural with:
The phosphate analogue of kamarizaite.

Structurally related to afmite.

Chemically similar to allanpringite, santabarbaraite; further relation to mixed-valence Fe phosphates like beraunite, ferristrunzite, giniite, and others.

Structure details (Kolitsch et al., 2016): (1) 3 octahedrally coordinated (O) Fe(Al) sites, 2 tetrahedrally coordinated (T) As sites; (2) zigzag chains (along [1-10]) of dimers formed by 2 edge-sharing FeO6 octahedra, that corner-link to another octahedron; (3) mixed O-T framework formed by corner-linking of chains and tetrahedra; (4) layering || (001); (5) channels along [010].
