About AnniteHide

09118920017271921341712.jpg
Cape Ann, Massachusetts, USA
Formula:
KFe2+3(AlSi3O10)(OH)2
Colour:
Black, brown
Lustre:
Vitreous
Hardness:
2½ - 3
Specific Gravity:
3.3
Crystal System:
Monoclinic
Name:
Originally named in 1868 by James Dwight Dana for a ferrian mica, but redefined as a ferroan mica by Alexander N. Winchell in 1925. Both authors named a mineral after the same locality at Rockport, Cape Ann, Essex Co., Massachusetts, USA.
Mica Group. Biotite series, forms a series with Phlogopite and other micas.
The Fe analogue of phlogopite, shirozulite, and hendricksite. The Al analogue of tetraferriannite. The hydroxyl analogue of fluorannite. Also the K analogue of the rubidium-dominant species UM2003-31-SiO:AlHLiRb.
Chemically similar to (the Al-richer) siderophyllite.

Compare the structurally and (somewhat) chemically related meifuite.

nα = 1.625 - 1.631 nβ = 1.69 nγ = 1.691 - 1.697
2V:
Calculated: 12° to 36°
Max. Birefringence:
δ = 0.066
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.

Surface Relief:
Moderate
Dispersion:
weak to distinct (r < v)
Comments:
brown (X), dark brown (Y=Z)
Comments:
Orientation: Y=b; measured 2V according to the Handbook of Mineralogy is from 0 to 5 deg.

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) 7.6382% 2,368 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!

DistanceDose rateRisk

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
