About Steenstrupine-(Ce)Hide

Knud J. V. Steenstrup

Formula:

Na₁₄Mn²⁺₂Fe³⁺₂Ce₆Zr(Si₆O₁₈)₂(PO₄)₆(PO₃OH)(OH)₂ · 2H₂O

Colour:

black, dark brown, red-brown

Lustre:

Vitreous, Greasy

Hardness:

4 - 5

Specific Gravity:

3.38 - 3.47

Crystal System:

Trigonal

Member of:

Steenstrupine Group

Name:

Named in honor of Knud Johannes Vogelius Steenstrup (7 September 1842, Høstemark Mill, Mou, Northern Jutland, Denmark – 6 May 1913, Frederiksberg, Denmark), geologist and explorer of Greenland, who discovered the mineral. He worked at the University of Copenhagen Geological Museum from 1866 to 1889, making nine journeys to Greenland, one of which lasted 2.5 years. He proved that the iron at Disko was from native extrusions and not from meteorites. From 1889 until his death, he was state geologist at the Geological Survey of Denmark.

Originally named simply steenstrupine. The suffix was added in 1987 (Nickel and Mandarino) to denote the dominant rare earth element, according to the Levinson rule.

Type Locality:

ⓘ Kangerluarsuk Fjord, Ilímaussaq complex, Kujalleq, Greenland

Optical Data of Steenstrupine-(Ce)Hide

Type:

Uniaxial (-)

RI values:

n_ω = 1.665 - 1.667 n_ε = 1.662 - 1.663

Max. Birefringence:

δ = 0.003 - 0.004
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:

Very 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

Pleochroism:

Weak

Comments:

brown and yellow tints.
