Name:
Named in 1925 by Charles Palache and Helen E. Vassar in honor of US geologist, Raphael Pumpelly [September 8, 1837 Owego, New York, USA – August 10, 1923 Newport, Rhode Island, USA]. The chemical suffix was added in 1973 by the IMA. Pumpelly was an active mining consultant and was professor of Mining Science at Harvard University. He was appointed director of the New England branch of the U. S. Geological Survey in 1884.

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.
