Barytolamprophyllite is a complex barium potassium titanium silicate. Barytolamprophyllite is a member of the lamprophyllite group, itself part of the seidozerite supergroup (Sokolova & Cámara, 2017). The name barytolamprophyllite acknowledges its barium content and relationship to lamprophyllite (Dudkin, 1959). The root name lamprophyllite combines Greek lampros and phyllon, for shining and leaf respectively, in recognition the mineral's lustrous cleavage (Hackman, 1894). Chemical analyses of barytolamprophyllite from this locality appear in Chakhmouradian & Mitchell (2002).
Barytolamprophyllite forms brown blades to 13 mm in a matrix of green aegirine and microcline. From the collection of E.R. Laskowski (1949-2020), a mining engineer who retired to Tucson, Arizona.
