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).
Type Locality:
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).

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.

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.
