Abstract

With accessory minerals of the Ce-group as well as the Y-group elements, the Black Cloud deposit near Divide, Colorado, is unique for the area. This lensoid pegmatite in the Pikes Peak granite measures 350 X 110 ft. and is sharply zoned with a 50 ft. thick quartz core. Irregular fluoritic and albitic replacement lenses, about 4 ft. long, contain allanite, gadolinite, thorite, beryl, bertrandite, smarskite, yttrotantalite, fergusonite, monazite, xenotime, fluocerite, and 3 types of fluorite. This is the second recorded occurrence of fluocerite and yttrotantalite. X-ray, chemical, and microscopic data are given for fluocerite.
