What is "kukharenkoite-"

Kukharenkoite-(Ce) is a barium cerium fluoride carbonate mineral, formula BaCeF(CO). It was identified from samples found in the Mont-Saint-Hilaire alkaline intrusive complex, Quebec, and the Khibiny Massif, Kola peninsula, Russia. It was named for Russian mineralogist Alexander A. Kukharenko (1914–1993).

The similar zhonghuacerite, a cerium containing mineral from China, is considered to be either kukharenkoite-(Ce) or huanghoite-(Ce) rather than a valid mineral.
