Röntgenite-(Ce) : Ca₂(Ce,La)₃[F₃\|(CO₃)₅], Huanghoite-(Ce) : BaCe[F\|(CO₃)₂], Aegirine : NaFe³⁺[Si₂O₆], Fluorite : CaF₂
	East Mine, Bayan Obo (Bayun-Obo; Baiyunebo) deposit, Bayan Obo, Darhan Muminggan United Banner, Baotou League, Inner Mongolia Autonomous Region, China Massive brown röntgenite-(Ce) grains with minor yellow finegrained rims of huanghoite-(Ce) in aegirine metasomatite with dark-violet fluorite. Empyrical formula of the röntgenite is (Ca1.78Sr.19)1.97(Ce1.30Nd1.08La.34Pr.20Sm.11)3.03[CO3]5(F2.97O.03)3. FOW ~6x4 mm. Pavel M. Kartashov microprobe identification, collection and photo.

Röntgenite-(Ce) : Ca₂(Ce,La)₃[F₃\|(CO₃)₅], Apatite-(CaF) : Ca₅[F\|(PO₄)₃]
	Tomtor Massif, Polar Yakutia, Saha Republic (Sakha Republic; Yakutia), Eastern-Siberian Region, Russia SEM image. Bright in BSE inclusions of rontgenite-(Ce) in fluorapatite crystal from heavy concentrates of rare metal ore. It is well visible, that apatite continued growth some time after rontgenite formation. Apparently this is the first occurrence of rontgenite in Russia. Andrey V. Mokhov photo. Pavel M. Kartashov identification.
