Реферат:	eng: 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 of cotectic melts. The most favorable environments for the formation of productive ore-forming systems were numerically simulated Among them are magmatic gas flows and fluid systems of mixed type. Magmatic fluid systems related to the retrograde boiling of cotectic melts in presence of localized sink of volatiles into permeable zones from apophyses in the chamber roof would evolve by two ways: (1) at L 2/h < 1 for intrusion thickness (L 2) and height of apophysis (h), the systems exist as high-temperature quasistationary fluid systems discharging on the surface of volcanic edifices; (2) at L 2/h > 1, the central part of the stock is overcooled and magmatic fluid system ceases to be active after all gas dissolved in the upper half of the stock has been exhausted. Such cases are favorable for the formation of fluid systems of mixed type. © 2013 Pleiades Publishing, Ltd.
