About WurtziteHide

03667220017271927752653.jpg
Charles Adolphe Wurtz
Formula:
(Zn,Fe)S
Colour:
Dark reddish-brown to black, orange-brown
Lustre:
Resinous
Hardness:
3½ - 4
Specific Gravity:
4 - 4.1
Crystal System:
Hexagonal
Member of:
Name:
Named in 1861 by Charles Friedel in honour of Charles Adolphe Wurtz (26 November 1817, Wolfisheim, near Strasbourg, France - 10 May 1884, Paris, France), French chemist who promoted ideas of atomic structure and organic chemistry. Wurtz was a laboratory assistant for Jean Baptiste Dumas at the École de Médecine and succeeded Dumas and was later appointed Professor of organic and mineral chemistry and eventually promoted to dean of the college. Wurtz was appointed chair of organic chemistry at the Sorbonne. Wurtz was one of the most influential chemists in the world, he received many honours in his lifetime, and his name is one of 72 scientists, mathematicians, and engineers whose name is on the Eiffel Tower. Biography by Rocke (2001).
Polymorph of:
Usually found as black to dark reddish-brown massive resinous to sub-metallic material, also as botryoidal banded crusts, and more rarely as hemimorphic pyramidal, or tabular, crystals.
Several polytypes are known; the hexagonal 2H polytype is the most common. Haussühl and Müller (1963) also mention the 4H, 6H, 8H, 10H, and 15R ones.

Wurtzite has a lower surface energy than sphalerite, which causes a reversal in phase stability at the nanoscale, with wurtzite energetically stable for particle sizes below 10 nm. The sphalerite-wurtzite transformation is a function of particle size and temperature, which can explain the occurrence of the zinc sulfide polymorphs in environments as diverse as ore bodies and planetary atmospheres (Subramani et al., 2023).

Forms a series with greenockite, hexagonal CdS.

Optical Data of WurtziteHide

Type:
Uniaxial (+)
RI values:
nω = 2.356 nε = 2.378
Max. Birefringence:
δ = 0.022
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:
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.
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.
Internal Reflections:
Yellow to dark brown
