GadoliniteCe

Gadolinite-(Ce) is a mineral belonging to the gadolinite group. It is a silicate of cerium, yttrium, iron, and beryllium. The chemical formula for gadolinite-(Ce) is Y2FeBe2(SiO4)2O2. It is characterized by the presence of cerium (Ce) as the dominant rare earth element, distinguishing it from other members of the gadolinite group like gadolinite-(Y). Gadolinite-(Ce) typically occurs as prismatic crystals, often exhibiting a vitreous luster and a color ranging from black to brownish-black or dark green. It is relatively dense and hard. This mineral is found in pegmatites and granite intrusions, often associated with other rare earth minerals. Notable occurrences include those in Norway, Sweden, Greenland, and the United States. Gadolinite-(Ce) is primarily of scientific interest due to its complex chemical composition and its role as a source of rare earth elements, particularly cerium and yttrium. Its economic significance is generally limited compared to other rare earth minerals.
