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.

Not fluorescent.
Other Information
IR Spectrum:
IR absorption shows absorption bands for H2O. A strong intensity band at 3293 cm-1 with a shoulder at 3123 cm-1 due to O-H stretching. A medium intensity band at 1665 cm-1 due to H-O-H bending. Also a very strong band at 1042 cm-1 and a medium strong band at 1143 cm-1 due to fundamental stretching for phosphate.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
