Description: In the context of geothermal gradient, liquid contained in inclusions in crystals and mainly in pores between them moves towards increasing temperature. The liquid is accumulating elements with distribution coefficients <1 with respect to major rock minerals, volatile and rare, particularly for platforms, elements âE" material for forming magmas of kimberlite composition. Inflow of volatiles to depth implies a decrease in temperature of solid rocks transition in semi-liquid state, pressure increase, and, upon exceeding the "roof" strength, leads to eruption. Inflow of aqueous solutions to volcanic magma chambers is one of the reasons for their awakening. Cycle of water movement is distinguished: atmosphere-soil-pores-mantle (volcanoes)-atmosphere. The phenomenon of water transfer into magma is directly related to the preparing Yellowstone Supervolcano eruption.
