Name:
Named simply chernovite in 1967 by B. A. Goldin, N. P. Yushkin, and M. V. Fishman in honor of Aleksandr Aleksandrovich Chernov (Александр Александрович Чернов) (11 (23) July 1877, Solikamsk, Russian empire – 23 January 1963, Syktyvkar, USSR), geologist, Institute of Geology, Syktyvar, Russia, explorer of the Polar Urals and professor at the Moscow State University and Academy of Sciences of the USSR. The suffix/modifier was added in 1987 to conform to the Levinson rule for species with essential REE indicating, in this case, a predominance of yttrium.
