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.

Soluble in water
Special Storage/
Display Requirements:
Display Requirements:
Although calciodelrioite has a structure that is very similar to rossite, with which it is commonly associated, rossite is almost always partly to completely altered to the lower hydrate, metarossite, whereas calciodelrioite exhibits no evidence of such alteration.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
