About ShcherbakoviteHide

Dmitri Ivanovich Shcherbakov (1893-1966)

Formula:

(K,Ba)KNa(Ti,Nb)₂(Si₄O₁₂)O₂

Colour:

Dark brown

Lustre:

Vitreous, Greasy

Hardness:

6½

Specific Gravity:

2.968

Crystal System:

Orthorhombic

Member of:

Batisite Group

Name:

Named by E.M. Es'kova and M.E. Kazakova in 1954 in honor of Dmitri Ivanovich Shcherbakov (13 January 1893 - 25 May 1966, Moscow, Russia) geochemist and mineralogist.

Type Locality:

ⓘ Apatitovyi Tsirk, Rasvumchorr Mine, Rasvumchorr Mt, Murmansk Oblast, Russia

Batisite Group.
Easily confused with batisite.

Note: the "shcherbakovite" described by Mitchell (1990) is in fact noonkanbahite.

Optical Data of ShcherbakoviteHide

Type:

Biaxial (-)

RI values:

n_α = 1.707 n_β = 1.745 n_γ = 1.776

2V:

Measured: 82° , Calculated: 82°

Max. Birefringence:

δ = 0.069
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

Rotation:

Surface Relief:

Moderate

Dispersion:

r > v

Pleochroism:

Visible

Comments:

X = pale yellow; Y = yellow; Z = brownish yellow.

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)	14.6640%	4,546	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!

Mass of radioactive mineral:

Shielding material:

Activity: –

Distance	Dose rate	Risk
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 (μ_shield). 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 = ((A_U × Γ_U) + (A_Th × Γ_Th) + (A_K × Γ_K)) / r² × μ_shield
