Name:
Named for the chemical composition, in accordance with whiteite group nomenclature. The suffix indicates sequentially the dominant atom in the X, M1, and M2 structural positions. The root name is for John Sampson White, Jr. (30 September 1933, Monessen, Pennsylvania, USA -), associate curator of minerals, Smithsonian institution; founder, editor, and publisher (1970-1982) of the Mineralogical Record.
The fully manganian whiteite.

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.
