About Ardennite-(Si)
Formula:
~Mn2+4Al4(AlMg)(SiO4,AsO4)(SiO4)2(Si3O10)(OH)6
Member of:
Unapproved name for a member of the ardennite group, in which the As site (T4) is predominantly occupied by Si. This substitution is coupled to an increased content of six-coordinated Mn3+.
Orlandi et al. (2013) assume that this phase could be structurally related to lavoisierite.
Originally described by Pasero & Reinecke (1991), with Si:As up to 9:1 on the As site.
