Name:
The naming of the mineral is often attributed to Henry James Brooke and Arthur Connell in 1840. The original description was actually made by Robert Jameson who first described greenockite, and the first description was in “his journal”: The Edinburgh New Philosophical Journal. The mineral was named for Lord Greenock - later Earl Charles Murray Cathcart, 2nd Earl Cathcart [December 21, 1783, Walton-on-the-Naze, Essex, England, UK - July 16, 1859, St Leonards-on-Sea, Hastings, England, UK]. Earl Charles Murray Cathcart was a general in the British army and served as Governor of the Province of Canada. He was also the author of two papers: one on igneous rocks in Edinburgh, Scotland and one on coal in southern Scotland.
Dimorph of:
Typically found as yellow to red hemimorphic pyramidal crystals and earthy coatings. Caution should be used in sight identifying yellow cadmium sulfide coatings as hawleyite (dimorph of greenockite) is not a very rare species and occurs in identical appearing coatings and identical environments; furthermore some of these coatings can be X-ray amorphous ("xanthochroite").

Forms a series with wurtzite, hexagonal ZnS.

Optical Data of GreenockiteHide

Type:
Uniaxial (-)
RI values:
nω = 2.529 nε = 2.506
Max. Birefringence:
δ = 0.023
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.
Pleochroism:
Weak
Comments:
Uniaxial + for wavelengths red to blue-green
