Name:
In in honour of Professor Emanuel Mazor (March 30, 1933, Cottbous, Germany - 2021), who worked at the Department of Environmental Sciences and Energy Research, Weizmann Institute of Science in Israel.
The Ba analogue of tuite (Ca-dominant) and the P analogue of gurimite (V-dominant). One of the chemically simplest Ba minerals. Not directly analogous with farringtonite (Mg-dominant, monoclinic).
Compare alforsite.
Structure details:
* BaO12, BaO10, and PO4 polyhedra
* all the above are ordered along the c-axis, in the sequence PO4-BaO10-BaO12-BaO10-PO4.

Optical Data of Mazorite
Type:
Uniaxial (+)
RI values:
nω = 1.760(3) nε = 1.766(3)
Max. Birefringence:
δ = 0.006
Based on recorded range of RI values above.
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.
