Name:Named after the colour of the "type" specimen, which has been determined to be a mixture with no relationship to modern Lavendulan (Ondruš et al., 2006). Present day Lavendulan does not exhibit a lavender colour.
Dimorph of:Lemanskiite


Lavendulan Group

A polymorph of Lemanskiite, the Ca analogue of Zdenekite and the arsenate analogue of Sampleite.

Data regarding this species have been significantly defined in recent years [Ondruš et al (2006) and Giester et al (2007)], including a re-examination of Breithaupt's type specimen. That effort disclosed that the "type specimen" of Lavendulan was a mixture unrelated to present day Lavendulan. The second locality from which "Lavendulan" was found is Jachymov (Joachimsthal), Czech Republic; therefore, the type locality of the species was changed to the latter locality, pending any formal declarations to the contrary.
