Name:
Named in honor of Valery Mikhailovich Chubarov (Валерий Михайлович Чубаров) (b. 1948), Russian mineralogist and physicist at the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences in Petropavlovsk-Kamchatsky. A specialist in electron microprobe analysis, he made great contributions to the mineralogy of Kamchatka, including studies of many minerals from the fumarolic exhalations of the Tolbachik volcano.
