Named in honor of Yuriy Pavlovich Men'shikov (Юрий Павлович Меньшиков) (28 December 1934, Sayda-Guba, Murmansk - 21 March 2013) famous Russian mineralogist and roentgenoscopist from Apatity. He worked at the Geological Institute of the KF USSR Academy of Sciences (KSC RAS) and made mineralogical studies of the Kovdorsky, Lovozersky, and Khibinsky mountain ranges and other geological objects on the Kola Peninsula. He described or co-described 50 new minerals.
