Formula:
PbFe3+2(AsO4)2(OH)2
Fe3+ may be replaced by minor Zn.
Colour:
Orange-brown, red-brown; rarely green
Lustre:
Adamantine
Hardness:
4
Specific Gravity:
5.365 (Calculated)
Crystal System:
Monoclinic
Name:
Named in 1989 by Allan Pring E. Maud McBriar and William Birch in honor of Sir Maurice Alan Edgar Mawby (August 31, 1904, Broken Hill, Austalia - August 4, 1977, East Melbourne, Australia) for his contribution to the Australian mining industry and expertise in the minerals from Broken Hill. He was a metallurgist and mining executive. He identified 17 species from Broken Hill that had not previously been reported from there. He was knighted in 1963.
Dimorph of:
Tsumcorite Group.
The monoclinic dimorph of Carminite.

May be confused with arsenbrackebuschite, also a Pb-Fe-arsenate, but which a much higher Pb content.

Type:
Biaxial (-)
RI values:
nα = 1.94(2) nβ = 2.00(2) nγ = 2.04(2)
2V:
Measured: 80° (5), Calculated: 76°
Max. Birefringence:
δ = 0.100
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.

Surface Relief:
Moderate
Dispersion:
relatively weak
Pleochroism:
Weak
Comments:
brown to reddish brown
