Colourless, light tan; colourless in transmitted light.
Lustre:
Sub-Vitreous, Pearly
Hardness:
3

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.

Optical Data of MooreiteHide

Type:
Biaxial (-)
RI values:
nα = 1.533 nβ = 1.545 nγ = 1.547
2V:
Measured: 50° to 50°
Birefringence:
0.014
Max. Birefringence:
δ = 0.014
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.

Surface Relief:
None to Very Low
Relative to Canada balsam mounting medium (n ≈ 1.537).

This shows the grain boundary and Becke line effect under plane-polarised light, based on the contrast between this mineral's average refractive index and the mounting medium. It does not take into account mineral colouration.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
Dispersion:
weak
Optical Extinction:
