About WitheriteHide

07326980017271927714305.jpg
William Withering
Formula:
BaCO3
Colour:
Colourless, white, greyish, light yellow; colourless in transmitted light.
Lustre:
Vitreous, Resinous
Hardness:
3 - 3½
Specific Gravity:
4.289 - 4.293
Crystal System:
Orthorhombic
Member of:
Name:
Named by Abraham Gottlob Werner in 1789 after William Withering (17 March 1741, Wellington, Shropshire, England - 6 October 1799, Birmingham), English physician and naturalist, who first described the mineral.
The Ba analogue of strontianite and aragonite.
Found in low-temperature hydrothermal vein deposits.
Forms a series with strontianite.

Compare 'UM1974-03-CO:BaCaMg'.

Note on the type locality:
It was for a long time assumed to be Alston Moor, Eden, Cumbria, but Cotterell (2022) demonstrated that there is "evidence to show that Alston Moor was 'fabricated' as the Type Locality and that the real source was Anglezarke in Lancashire" (https://www.mindat.org/mesg-625213.html).

Optical Data of WitheriteHide

Type:
Biaxial (-)
RI values:
nα = 1.529 nβ = 1.676 nγ = 1.677
2V:
Measured: 16° , Calculated: 8°
Max. Birefringence:
δ = 0.148
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:
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.
In focus
Interference Figure:
This shows the idealized biaxial acute bisectrix (Bxa) interference figure - the conoscopic view for a grain cut perpendicular to the acute bisectrix, using this mineral's 2V. The two small white dots mark the melatopes - the points where the two optic axes emerge - and are shown only when they fall within the field of view. The coloured bands are isochromatics, and the dark bands are isogyres.

Rotate the stage: at 0°/90° the isogyres form a cross through the melatopes; at 45° they pull apart into curved hyperbolas. That splitting on rotation - absent in a uniaxial figure - is the standard diagnostic test for telling biaxial minerals from uniaxial ones. If 2V is large, the melatopes may fall outside the field of view, as they often do at the microscope too.
Dispersion:
relatively weak

Other InformationHide

Thermal Behaviour:
Inverts under CO2 pressure to a hexagonal (?), and then an isometric modification upon heating.
Notes:
Soluble in dilute HCl.
Health Risks:
Barium Carbonate is toxic if ingested, and it has been used as a rat poison. Handling of Witherite is not a major cause of concern as long as you avoid breathing in dust (such as may be generated by grinding, sawing or trimming specimens) and you wash your hands after handling.

MSDS Data sheet on Barium Carbonate - NOTE this refers to the powder which is more dangerous to handle than crystalline Witherite.
Oral ld50 between 100 and 300mg/kg.
