مطالعه ی تولید و مهاجرت مذاب در مناطق فرورانش به کمک شبیه سازی جریان دو فاز

In this study we investigate the production and migration of melt in subduction zones with the aid of a numerical simulation. We solve the governing equations of the flow of a fluid melt phase through a porous and deforming mantle rock. We investigate the volume of melt produced and its subsequent movement under a variety of conditions. We find that the nonlinear dependence of the mantle rock permeability on its porosity is the defining factor in the time variations of melt production and the pattern of migration through the mantle. Furthermore, we investigate the importance of other parameters, such as the age of the subducting plate, and subduction dip and velocity.
