Calculated relative values outcome of SiO (sub 2) , Fe (sub 3) O (sub 4) , MgO, Al (sub 2) 0 (sub 3) , Na (sub 2) O, K (sub 2) O, H (sub 2) O, F and of some metals from ore-giving phase pluton Akthatay. The received results testify that ore-forming "fluids" represented melt-fluid silica and alkalis. Structure of a melt-fluid separated from residual magma, as a first approximation, looks as follows, %: SiO (sub 2) --63,5; Fe (sub 2) O (sub 3) --8,6; MgO--1,32; Al (sub 2) O (sub 3) --7,0; H (sub 2) O--12,3; Na (sub 2) O--1,7; K (sub 2) O--3,7; F--1,5; Sigma Metals-0,3.Other references
