About AlluauditeHide

01457560017271920909494.jpg
François Alluaud
Formula:
(Na,Ca)Mn2+(Fe3+,Mn2+,Fe2+,Mg)2(PO4)3
Colour:
Dirty yellow to brownish yellow, grayish green; surficially dull greenish black, brownish black, black, when altered
Hardness:
5½ - 6
Specific Gravity:
3.4 - 3.5
Crystal System:
Monoclinic
Name:
Named by Alexis Damour in 1847 in honor of François Alluaud (II) [September 21, 1778-February 18, 1866], of Limoges, France, ceramicist and mineralogist who discovered the Chanteloube material. François Alluaud (I) was director of the Royal Limoges porcelain factory and founded his own porcelain factory in 1798 and died in 1799. His son, François Alluaud (II) was already a ceramicist, presumably working for his father and wrote mineralogical articles, etc. from 1808 through 1855 and received the Legion of Honor in 1858. François Alluaud (II) was mayor of Limoges 1830-1833. (Encyclopedia of Ceramics (1902) by William Percival Jervis.) François Alluaud named hureaulite (1825) and heterosite (1826).
Alluaudite Group. Alluaudite-Ferroalluaudite Series.

The original alluaudite from the type locality did not contain appreciable ferrous iron and was originally defined more or less as it is in the present day, but for new knowledge about mineral structure, etc. In 1937, Percy Quensel unsuccessfully introduced mangan-alluaudite to supersede simple alluaudite and then used alluaudite to accommodate ferrous iron-bearing material. Quensel's usage was rejected in Dana's System of Mineralogy, 7th edition.

Occurs as an alteration product of Varulite and Arrojadite-(KFe).

Optical Data of AlluauditeHide

Type:
Biaxial (+)
RI values:
nα = 1.782 nβ = 1.802 nγ = 1.835
2V:
Measured: 50° to 90°, Calculated: 78°
Max. Birefringence:
δ = 0.053
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:
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.
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:
r > v moderate
Pleochroism:
Weak
Comments:
X = pale olive-green, straw-yellow to greenish yellow; Z = pale olive-greenish to brownish yellow.
