About WiluiteHide

Formula:

Ca₁₉MgAl₄(Al,Mg)₈(B,◻)₄◻[Si₂O₇]₄[(SiO₄)₁₀]O(O,OH)₉

The formula is a partial simplification of the full structural formula. The large (VII-IX)-coordinated (X4)₂(X3)₈(X2)₈(X1) sites are here combined (e.g. Ca₁₉) and are typically filled with Ca, although other large cations such as the REE may be present. The square-pyramidal Y1 site can host a variety of M²⁺ and M³⁺ ions and is the basis for the distinction of several species. The VI-coordinated Y2 site typically is filled with Al, whereas the also VI-coordinated Y3 site may contain Al, Mg, and other cations of similar charge and size. The tetrahedral T1 site is typically vacant but may contain B (less commonly Al); the trigonal T2 site is also typically vacant but may also contain B. Some of the (SiO₄) may be replaced by (H₄O₄), akin to the Si⁴⁺ ↔︎ 4H⁺ hydrogarnet substitution. Among the oxygen that are not part of the silica tetrahedra, there are eight "O11" that typically occur as OH, two "O10" that are typically O & OH or OH & OH (the latter arrangement notably when Y1 is an M²⁺ cation). There may also be up to three "O12" that in most vesuvianite-group minerals are absent (and are not included here), but may be present particularly when T1 is occupied.

With increased filling of the T2 site by B, various charge balance mechanisms involving either increased O for OH in the "O11" position and/or increased M²⁺ for M³⁺ substitution in the Y3 site are necessary (see idealized formula for full T2 occupancy by B). In lieu of an explicitly defined "end-member" wiluite, more generic representations of site fillings are retained here, pending newer data.

Optical Data of WiluiteHide

Type:

Uniaxial (+)

RI values:

n_ω = 1.721(2) n_ε = 1.725(2)

Max. Birefringence:

δ = 0.004
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.

Thickness: 30 µm Order divisions

Rotation:

Surface Relief:

Very High (positive)
Relative to Canada balsam mounting medium (n ≈ 1.537).

This shows the grain boundary and Becke line effect under plane-polarised light, based on the contrast between this mineral's average refractive index and the mounting medium. It does not take into account mineral colouration.

Focus:

In focus

Interference Figure:

This shows the idealized uniaxial interference figure - the conoscopic (convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis centred and vertical. The coloured rings are isochromatics, computed with the same physics as the Michel-Lévy bar above; the dark cross is the isogyre.

For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.

Thickness: 30 µm
