摘要: A two-dimensional mathematical model is proposed to describe the crystallization of magmatic bodies with roof complicated by apophyses, around which fluidogenic ore deposits could be formed during retrograde boiling cotectic melts. The most favorable environments for formation productive ore-forming systems were numerically simulated Among them are gas flows and fluid mixed type. Magmatic related melts in presence localized sink volatiles into permeable zones from apophyses chamber would evolve two ways: (1) at L2/h 1, central part stock overcooled system ceases active after all dissolved upper half has been exhausted. Such cases
