Реферат: eng: The morphology and internal convective structure of continuous roll flows in magma melts were experimentally studied with regard to peripheral (shallow) magma chambers and downgoing circular gravity flows in conduits. We found properties of continuous convective mixing in a magma melt in a peripheral chamber due to convective roll flows. We investigated the mechanism that is responsible for cumulus generation at the bottom of a peripheral chamber when homogeneous and heterogeneous melts are emplaced. We conducted an experimental study of how the contact surface is formed at the cumulus-melt boundary. We made a qualitative study of the mechanism that affects the composition of magma melts over time in a peripheral and a mantle (deeper) chamber owing to crystallization, as well as the special mechanism that is responsible for cumulus generation in the peripheral chamber. © 2011 Pleiades Publishing, Ltd.
