Formula:
Mg(CH3SO3)2 · 12H2O
Colour:
Colourless
Lustre:
Waxy
Specific Gravity:
1.364 (Calculated)
Crystal System:
Trigonal
Name:
Named in 2013 by F. E. Güner Genceli, T. Sakurai, and T. Hondoh in honor of Ernst A.J. Burke (August 19th 1943, Kortrijk, Belgium), mineralogist specializing in opaque minerals and Raman spectrometry of fluid inclusions, and professor at the Vrije Universiteit Amsterdam, Netherlands. Former Head of the IMA Commission on New Minerals, Nomenclature and Classification.
The first and only methanesulphonate mineral. One of a few Mg-S-C-H minerals. Third natural compound of only magnesium and an organic acid, after dashkovaite and glushinskite. Known as a synthetic compound with the chemical name magnesium methanesulphonate hydrate.

Optical Data of ErnstburkeiteHide

Type:
Uniaxial (+)
RI values:
nω = 1.402(1) nε = 1.408(1)
Max. Birefringence:
δ = 0.006
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:
Moderate
Pleochroism:
Non-pleochroic
Comments:
Optical properties were collected on synthetic material.
