Gagarinite-(Ce)
http://dbpedia.org/resource/Gagarinite-(Ce) an entity of type: Thing
La gagarinita-(Ce) (inicialment anomenada zajacita-(Ce)) és un mineral de la classe dels halurs. Anomenada en honor de Iuri Gagarin, el primer cosmonauta. Inicialment anomenada zajacita-(Ce) en honor del Dr. Ihor Stephan Zajac, el geòleg que va liderar l'exploració que va localitzar el mineral. Un sinònim del seu nom és el codi IMA1993-038. és l'anàleg de ceri de la gagarinita-(Y).

Gagarinite-(Ce) previously zajacite-(Ce) is a rare radioactive fluoride mineral with formula Na(REExCa1−x)(REEyCa1−y)F6. REE refers to rare-earth elements, mostly those belonging to the lanthanide series. It crystallizes in the trigonal rhombohedral system and has a white vitreous appearance with a conchoidal fracture. It has a Mohs hardness of 3.5 and a specific gravity of 4.44 to 4.55. Zajacite is transparent with refractive indices nω = 1.483 and nε = 1.503. Gagarinite-(Y) is a yttrium-rich analog.

It occurs as creamy to white anhedral to subhedral grains in pegmatite and aplite pods or lenses in a peralkaline igneous intrusion. It was discovered in 1993 at , Quebec – Labrador, (56°20'N, 64°10'W) and was initially named for , who led the expedition responsible for its discovery, and who first recognized the presence of the new mineral. The mineral was renamed gagarinite-(Ce) in 2010 by the IMA. The new name is for Russian cosmonaut Yuri Gagarin (1934–1968).
