About WinchiteHide

Formula:
◻(CaNa)(Mg4Al)(Si8O22)(OH)2
The winchite-group minerals are defined as sodium-calcium amphiboles with A(Na+K+ 2Ca)<0.5 apfu and with C(Al+Fe3++2Ti)<1.5 apfu. The W position may contain (OH),F or Cl.

Winchite is defined with
C2+ position: Mg dominant
C3+ position: Al dominant
W position: (OH) dominant.
Colour:
Cobalt-blue to violet-blue, lavender-gray, gray, colorless
Lustre:
Vitreous
Hardness:
5 - 6
Specific Gravity:
2.97 - 3.175
Crystal System:
Monoclinic
Name:
Named in honour of Howard James Winch (1877, Buckhurst Hill, Essex, England - 1964, Essex, England) analytical chemist, mineralogist, metallurgist, and mining engineer with the Kajlidongri quarry, who discovered of the mineral. He also discovered hollandite.
Compare the chemically similar richterite.

The Kajlidongri mine, Madhya Pradesh, India, is generally considered to be the type locality for winchite, but since Fe3+ >> Al the mineral composition of the mineral found here corresponds to a ferri-winchite composition. See locality page for further information.

Optical Data of WinchiteHide

Type:
Biaxial (-)
RI values:
nα = 1.629 nβ = 1.643 nγ = 1.650
2V:
Measured: 64° (2)
Max. Birefringence:
δ = 0.021
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.

Surface Relief:
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.
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.
Dispersion:
weak
Pleochroism:
Visible
