As of 1963 he is affiliated with the Institute of Geology and Mineralogy, Siberian Branch of the Russian Academy of Sciences (Novosibirsk). He published more than 250 papers and 8 monographs, dedicated to geology, petrology, petrochemistry , mineralogy, geochemistry, and metallogeny of mafic-ultramafic associations of Chukotka, Kamchatka, Sakhalin Island, Transbaykalia, Mongolia, Urasl, Tian-Shan, Northern Pamir, and other regions. Zusammenfassung Providing an overview of the world's literature on analytical data and theoretical concepts of the regularities of rare earth elements in ultramafic and mafic rocks of different chemical and mineral compositions, the book is intended for specialists and students in petrology and geochemistry of ultramafic, mafic, and other types of igneous rocks. Inhaltsverzeichnis Rare earth elements in ultramafic rocks from mafic-ultramafic massifs of folded regions. Rare earth elements in ultramafites from deep xenoliths in alkali basalts. Rare earth elements in hypabyssal and subvolcanic rocks high in magnesium composition. Rare earth elements in plutonic mafic rocks. Rare earth elements in rock-forming minerals from ultramafic and mafic rocks. Indicator properties of rare earth elements and their role in studies of genesis of rocks and minerals from mafic-ultramafic complexes.
