About Zinclipscombite
William Nunn Lipscomb, Jr.
Formula:
ZnFe3+2(PO4)2(OH)2
Colour:
Dark green to brown
Lustre:
Vitreous
Hardness:
5
Specific Gravity:
3.65
Crystal System:
Tetragonal
Name:
Named as the zinc analogue of lipscombite.
The species lipscombite itself was named in honour of William Nunn Lipscomb, Jr. (9 December 1919, Cleveland, Ohio, USA - 14 April 2011, Cambridge, Massachusetts, USA), American inorganic and organic chemist, University of Minnesota, Minneapolis, Minnesota, USA, who determined the crystal structure of the synthetic compound. The name was originally given to synthetic material. Lipscomb was awarded the Nobel Prize in Chemistry in 1976 “for his studies on the structure of borates, illuminating problems of chemical bonding”.

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.
