About NephelineHide

Formula:
Na3K(Al4Si4O16)
Colour:
Colourless, white, grey, yellowish
Lustre:
Vitreous, Greasy
Hardness:
5½ - 6
Specific Gravity:
2.55 - 2.66
Crystal System:
Hexagonal
Name:
From the Greek "nephele" for "cloud" since it turns cloudy when treated with strong acid.
Dimorph of:
A very important change concerning nepheline is found in the recent (42nd) IMA Newsletter: potassium is essential in nepheline and the formula is changed to that recognized by Mindat. See https://www.mindat.org/mesg-437726.html for details, and CNMNC Newsletter No. 42, April 2018.

A rock-forming mineral, and classed as a feldspathoid. Common in nepheline syenite, an igneous rock often found in alkaline complexes.

Can bear some water (admixture).

Likely polymorphous with so-called carnegieite and 'α-carnegieite'.

Compare the related kalsilite and 'UM1967-10-SiO:AlHNa', the latter being possibly a natural analogue of "nepheline hydrate".

The presence of satellite reflections seems to be a universal property of nepheline (Vulić et al., 2011); most samples show a practically complete Si-Al-ordering, but some exhibit disorder up to 20%.

Under subsolidus conditions, nepheline is intensively replaced by numerous secondary minerals, of which various zeolites (mainly natrolite, analcime, gonnardite), as well as cancrinite, muscovite and Al-O-H phases (gibbsite, böhmite, nordstrandite) are the most common.

eBay Warning: Some dealers on eBay are selling aragonite specimens as 'nepheline'. Avoid any orange-brown hexagonal clusters listed from China as they are not nepheline at all.

Optical Data of NephelineHide

Type:
Uniaxial (-)
RI values:
nω = 1.529 - 1.546 nε = 1.526 - 1.542
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.

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 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.

RadioactivityHide

Radioactivity:
Element % Content Activity (Bq/kg) Radiation Type
Uranium (U) 0.0000% 0 α, β, γ
Thorium (Th) 0.0000% 0 α, β, γ
Potassium (K) 6.6912% 2,074 β, γ

For comparison:

  • Banana: ~15 Bq per fruit
  • Granite: 1,000–3,000 Bq/kg
  • EU exemption limit: 10,000 Bq/kg

Note: Risk is shown relative to daily recommended maximum exposure to non-background radiation of 1000 µSv/year. Note that natural background radiation averages around 2400 µSv/year so in reality these risks are probably extremely overstated! With infrequent handling and safe storage natural radioactive minerals do not usually pose much risk.

Interactive Simulator:

Note: The mass selector refers to the mass of radioactive mineral present, not the full specimen, also be aware that the matrix may also be radioactive, possibly more radioactive than this mineral!

Activity:

DistanceDose rateRisk
1 cm
10 cm
1 m

The external dose rate (D) from a radioactive mineral is estimated by summing the gamma radiation contributions from its Uranium, Thorium, and Potassium content, disregarding daughter-product which may have a significant effect in some cases (eg 'pitchblende'). This involves multiplying the activity (A, in Bq) of each element by its specific gamma ray constant (Γ), which accounts for its unique gamma emissions. The total unshielded dose at 1 cm is then scaled by the square of the distance (r, in cm) and multiplied by a shielding factor (μshield). This calculation provides a 'worst-case' or 'maximum risk' estimate because it assumes the sample is a point source and entirely neglects any self-shielding where radiation is absorbed within the mineral itself, meaning actual doses will typically be lower. The resulting dose rate (D) is expressed in microsieverts per hour (μSv/h).

D = ((AU × ΓU) + (ATh × ΓTh) + (AK × ΓK)) / r2 × μshield
