About LavoisieriteHide

Antoine Lavoisier
the full (crystal chemical) formula is: Mn2+8[Al10(Mn3+Mg)](SiO4)4(Si2O7)2(PO4)(Si3O10)(OH)12.
Specific Gravity:
3.576 (Calculated)
Crystal System:
Named in 2012 by P. Orlandi, C. Biagioni, M. Pasero and M. Mellini in honor of Antoine-Laurent Lavoisier (26 August 1743 – 8 May 1794), a French chemist and biologist. He is considered the 'father of modern chemistry'.
Related to sursassite and closely related to ardennite (= ardennite-(As) or ardennite-(V)). Also related to pumpellyite.

Complex multianion silicate-phosphate.

Lavoisierite represents a structural link between sursassite and ardennite.

Type Occurrence of LavoisieriteHide

General Appearance of Type Material:
Acicular and prismatic-tabular crystals, elongated on [010] and flattened on {001}, up to a few millimeters in length.
Place of Conservation of Type Material:
Museo di Storia Naturale e del Territorio, Università di Pisa, Calci (Pisa), Italy, catalogue number 19637, and the Museo Regionale di Scienze Naturali, Torino, Italy, catalogue number M/U16359
Geological Setting of Type Material:
In piemontite-bearing micaschists. The crystallization of lavoisierite is related to the Alpine tectono-metamorphic events involving (Mn, Al)-rich metasediments.
