Barytolamprophyllite ?
Formula: (Ba,Na)2(Na,Ti,Fe3+)4Ti2(Si2O7)2O(OH,F)
Description: 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, barytolamprophyllite sensu stricto was not detectable.
