About Nickelzippeite
Formula:
Ni2(UO2)6(SO4)3(OH)10 · 16H2O
The composition is given here in analogy to the compositions of cobaltzippeite, magnesiozippeite and zinczippeite, according to Burns et al. (2003). It is not entirely certain, though, since nickelzippeite has not been part of that study.
Colour:
Tan to brownish yellow, yellow-orange
Hardness:
5 - 5½
Crystal System:
Monoclinic
Member of:
Name:
Named nickel-zippeite by Frondel et al. in 1976 to distinguish it from other similar zippeite group minerals. The hyphen was removed by Burke in 2008.

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.

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.
No measured or calculated 2V is on file for this mineral, so the value used here (73°) is estimated from its recorded refractive indices and optic sign, not from a direct 2V measurement.
