Member of:Alluaudite Group
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).
