Name:
Named in 1929 by Lawson H. Bauer and Harry Berman in honor of Gideon Emmet Moore [August 21, 1842 New York, New York, USA - April 13, 1895 New York, New York, USA], American chemist, originally an assayer at Virginia City, Nevada, USA and worked mostly with the Passaic Zinc Company (1872-1895), and who early investigated the minerals of Sterling Hill and Franklin, New Jersey. He named brushite, chalcophanite, cryptokallite, hetaerolite, and the first natural occurrence of metacinnabarite.

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.
