About Tinticite
Formula:
Fe3+3(PO4)2(OH)3 · 3H2O
Colour:
Creamy white with yellowish or brownish tint, bright ocher-yellow
Lustre:
Dull
Hardness:
2½
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.
Type Locality:
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].

Biaxial
RI values:
nα = 1.745 nγ = 1.7455
Max. Birefringence:
δ = 0.001
Based on recorded range of RI values above.
Based on recorded range of RI values above.
Interference Colours:
The colours simulate birefringence patterns seen in thin section under crossed polars. They do not take into account mineral colouration or opacity.
Michel-Levy Bar The default colours simulate the birefringence range for a 30 µm thin-section thickness. Adjust the slider to simulate a different thickness.
Grain Simulation You can rotate the grain simulation to show how this range might look as you rotated a sample under crossed polars. Each grain retains its interference colour (retardation) while its brightness falls to black at extinction and reaches a maximum between extinction positions.
