Scales of mass transfer and differential mobility of major and rare-earth elements in metapelites during collisional metamorphism

摘要

Joint study of multicomponent chemical zonality of rock-forming minerals with actual metamorphic reactions in metapelite of Yenisey Range had been completed. Calculations of chemical equations, analysis of substance balance and peculiarities of changing of mineral composition during collision metamorphism of pelite attest to isochemical character of the processes in most of the system components.
