1977 Amer. Mineralogist 62 407/1 [Report of the Subcommittee on Pyrochlore Nomenclature of the IMA Commission on New Minerals and Mineral Names.] Obruchevite (Kalita, 1957) is a name later shown to have been given to two different species (Gorzhevskaya and Sidorenko, 1969). One of these, brown obruchevite, after heating to 700°C, crystallized to the samiresite S phase... The other, black obruchevite, was subsequently renamed yttropyrochlore (Kupriyanova, 1970, unpublished). The Soviet Union's Commission of New Minerals (KNM) and Mineralogical Terminology have recommended the name yttropyrochlore replace this type of obruchevite.
