Name:
First described in 1850 from Låven, Langesundsfjorden, Norway by the Norwegian mineralogist Paul Christian Weibye (1819-1865). It was found by him the year before, in 1849. The name is from the Greek κατα = 'with' and πλειον = 'more' and refers to its association with many other rare minerals.

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.
