Laws of conservation

Basic equations - conservation of mass, momentum and energy, rheological relationship, equation of state, boundary conditions.

Thermal convection in the Earth's mantle

Boussinesq approximation. Dimensionless quantities; Prandtl, Rayleigh and dissipation numbers. Boundary conditions. Static solution. Decomposition of a solenoidal field. 2-D modelling - stream function.

Basic characteristics of thermal convection

Linearized theory - onset of convection. Dependence of the style of the convection on the Rayleigh number. Influence of inner heating, compressibility, pressure- and temperature-dependent rheology and phase transitions.

Rheology and dynamics of subducted lithosphere

Seismic imaging of subducted lithosphere in the mantle. Rheology of subducted slabs. Phase transitions. Numerical modelling of subduction.
