UDC 552.3:550.42(571.151) PETROLOGY OF THE LAMINATED HARLOVSKY MASSIF IN THE GORNY ALTAI
The article considers the petrography, petrology, geochemistry and genesis of the laminated Harlovsky massif in the Gorny Altai. The attention is focused on characteristics and parameters of the fluid regime that have affected the sequence of magmatic liquates and differentiates and their ore content. Petrological aspects of the chambered and deep focal liquation and differentiation, caused the ore genesis in the Harlovsky massif, are distinguished. Data on the mantle source of the melting and intermixture with crustal material are given. The revealed M- and W-types of the tetrad effect of rare earth elements fractionation are closely tied up with the fluid regime characteristics.
Key words: laminated intrusive, ore pyroxenites, melanogabbro, leucogabbro, anorthosites, quartz monzonites, quartz syenodiorites, granosyenites, liquation, differentiation, mantle-crust interaction.
