About WavelliteHide

Formula:
Al3(PO4)2(OH)3 ยท 5H2O
May contain some F replacing OH.
Colour:
Green to yellowish-green and yellow, greenish white, yellowish-brown, brown, brownish-black, blue, white and colourless; colourless in transmitted light.
Lustre:
Vitreous, Greasy, Pearly
Hardness:
3½ - 4
Specific Gravity:
2.36
Crystal System:
Orthorhombic
Member of:
Name:
Named by William Babington in 1805 in honour of Dr. William Wavell (20 December 1750, Newchurch, Isle of Wight, England, UK - 15 May 1829, Barnstaple, England, UK), a physician, botanist, historian, and naturalist in Harwood Parish, Devonshire, England, who discovered the mineral. Non-contemporary accounts suggest that Dr. Wavell discovered phosphate in the mineral, a constituent that was previously missed in analyses of hydrargilite. Dr. Wavell was educated in Edinburgh and was in medical partnership with Dr. William Curtis (1746, Alton, Hampshire, England, UK - 1825, Barnstaple, Devonshire, England, UK) on Gracechurch Street, Barnstaple. Dr. Curtis was also an energetic botanist and also a correspondent with many naturalists (Curtis and Hooker, 1827).
A secondary mineral found most often in aluminous, low-grade metamorphic rocks. Usually found as radiating "starburst" clusters of green to yellow-green fibrous crystals on fracture surfaces in the matrix, these may grade into globular aggregates; more rarely in chalcedony-like or opaline masses, or stalactic; very rare as good distinct crystals.

The OH analogue of fluorwavellite.

Note: Allanpringite is a monoclinic-pseudoorthorhombic Fe3+-analogue of wavellite.

Optical Data of WavelliteHide

Type:
Biaxial (+)
RI values:
nα = 1.518 - 1.535 nβ = 1.524 - 1.543 nγ = 1.544 - 1.561
2V:
Measured: 60° to 72°, Calculated: 60° to 70°
Max. Birefringence:
δ = 0.026
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 ยตm 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.

Surface Relief:
None to Very Low
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.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
