Hydroxycalciopyrochlore, Niobophyllite, Monazite-(Ce)
SEM image of Nyobophyllite particle from from hand-picked concentrate of Ernst Nickel's part of holotype specimen. Note abundant inclusions of medium-bright in BSE octahedral crystals of Hydroxycalciopyrochlore. More rare brightmost irregular grains are Monazite-(Ce). Analytical data are available on daughter photos. Pavel M. Kartashov collection and photo; Locality: Mann 2, Seal Lake alkaline complex, Labrador, Newfoundland and Labrador, Canada;
