Physical chemistry of deformation and phase transitions within minerals:
Thermodynamics and stress
Theory and models of coherent transformation reactions within crystals: coherent exsolution, shear-induced coherent transitions, order-disorder transitions
Physical chemistry of deformation of polymineralic rocks under crustal conditions of temperature, pressure, humidity, etc.:
Physical chemistry of diffusion transfer in rocks, induced by stress (alias pressure solution) or by metamorphic reactions
Modelling and interpretation of textures caused by interaction of deformation with diagenetic and metamorphic reactions
Development of tectonic layering and cleavage
Fluid flow within and toward shear zones
Migmatization, migmatites, melting under stress
