Plumbomicrolite : (Pb,Ca,U)_2-x(Ta,Nb,Sn)₂O₆(O,[]), Albite (Var: Cleavelandite) : Na[AlSi₃O₈], Fluorite (Var: Yttrofluorite) : (Ca_1-xY_x)F_2+x where 0.05< x <0.3
	Ploskaya Mt, Western Keivy Massif, Kola Peninsula, Murmanskaja Oblast', Northern Region, Russia This is the first my real plumbomicrolite specimen - fragment of large enough monocrystal with well visible partition. This is more rare on the locality brownish-green variety of the mineral. Associating macro minerals are: beige tabular albite (var. cleavelandite) and crusts of late formed yttrofluorite-III (low yttrian, almost REE-free). ...
