Optical Data of MagnesiteHide

Type:

Uniaxial (-)

RI values:

n_ω = 1.7 n_ε = 1.509

Max. Birefringence:

δ = 0.191
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.

Thickness: 30 µm Order divisions

Rotation:

Surface Relief:

High (positive)
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.

Focus:

In focus

Interference Figure:

This shows the idealized uniaxial interference figure - the conoscopic (convergent-light, Bertrand-lens-in) view, for a grain cut with the optic axis centred and vertical. The coloured rings are isochromatics, computed with the same physics as the Michel-Lévy bar above; the dark cross is the isogyre.

For a genuinely uniaxial mineral viewed this way, that cross stays perfectly stationary if you rotate the stage - unlike a biaxial mineral, where it splits apart on rotation. That invariance is itself the standard diagnostic test for telling uniaxial and biaxial minerals apart at the microscope.

Thickness: 30 µm

Dispersion:

Very strong

Pleochroism:

Visible

Comments:

Cobaltian material dichroic:
E = Violet-red
O = Flesh-red

Fluorescence of MagnesiteHide

In UV light:

May exhibit pale green to pale blue fluorescence and phosphorescence.

Other InformationHide

Notes:

Triboluminescent at times.

Slightly affected by cold acids. Readily soluble in warm HCl with effervescence. Slightly soluble in water with the solubility increasing with the presence of NaCl, Na2SO4, or CO2.

Health Risks:

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
