Lamprophyllite Group from
Graulay (Graulai; Graulei; Grauley), Hillesheim, Vulkaneifel, Rhineland-Palatinate, Germany

Classification
Species:'Lamprophyllite Group' (not an IMA approved species)
Formula:A2PM2HM4O(Si2O7)2(XMO)2(XAO)2
Comments:Barytolamprophyllite (from the Eifel localities) was originally mentioned by Hentschel. He used this name to describe Ba-rich members of the Lamprophyllite-group. These minerals were investigated in more detail during the last years and turned out to be new Ba-rich species of the Lamprophyllite-group. (Schüllerite, Lileyite and the Fe-Analogon of Lileyite)
In the recent investigations Barytylamprophyllite sensu stricto was not detectable.
Confirmation
Validity:Believed Valid
