Zonal crystals of golden-brown Fluorbarytolamprophyllite owergrow cores of Fluorlamprophyllite within leucocratic Aegirine-Sodalite-Microcline syenite with disseminated impregnation of primary Villiaumite. Fluorine contents in these intergrowths vary from 4 to over 8 mas.%. Minor crystals of Loparite also presents in the rock. Collected by Mikhail Uchitel' in 2012 in dumps of adit #11 of the Kedyk area of the mine. Pavel M.
