Abstract

Numerical investigation of material flow induced by a descending oceanic plate has been carried out. Asymmetrical flow is modeled in two wedge-shaped regions located on different sides of the downgoing slab. The calculation of induced flow is two-dimensional, time dependent, with viscosity dependent on temperature. The calculation is very sensitive to rheological properties of material. Modeling of island-arc volcanism could be realized only by taking into account non-linear rheological behaviour of material like yielding, plasticity, etc. Induced flow then, may be a probable explanation for island-arc volcanism and high heat flow in marginal basins.
