dc.description.abstract | Peculiarities of behavior of the minor and trace elements, variations of the fluid parameters, isotopic compo-sition of oxygen in rocks and rock-forming minerals are analyzed for three, different in time and composition, plutons related to Svecofennian tectonomagmatic cycle in the Northern Ladoga region. As a result, the relation-ship has been detected between contents of some elements, H/C ratio in the fluid, temperature of the oxygen iso-topic equilibrium in the mineral associations and the isotopic composition of oxygen in the fluid. As far as values of H/C ratio and parameters defined through the distribution of oxygen isotopes correspond to subsolidus and the lower temperature alterations, the conclusion is made about a redistribution of minor and trace elements during the superimposed processes. Intensity of those alterations wasn't considerable enough to eliminate completely indices of the primary composition of magmas, as well as about conditions of their crystallization. | |
