Analogue modelling

• Melt formation and accumulation - Study of the production and accumulation of melt on the grain scale. We study the migration of melt in a crystalline aggragates and try to determine how melt migrates and concentrates along grain boundaries, This type of study is important for understanding the formation of basaltic and granitic melts, and to study the way in which melt can be separated from the host rock.
• Stress Corrosion Cracking and Instabilities at Phase Transitions - Study in collaboration with the PGP Center at the University of Oslo . Elastically stressed solids have unstable surfaces that can develop a roughness and crack like features (Anticracks) that can lead to brittle failure. For more information see Daniel’s Homepage.
• Development of Flanking Structures - These structures are important as shear sense indicators. We model them with analogue materials.
• Sandbox models of block rotation and rift interaction - DAAD project where we compare structures that develop in Sandbox models with numerical simulations and patterns in the East African Rift System.

Numerical modelling

• The development of Microstructures in low temperature Environments and their influence on the rheology of the Crust.
• Boudinage and Fracture spacing - study the spacing and development of fractures in competent layers.
• Dymanics of vein forming mechanisms - study in detail the formation and dynamics of veins including hydrofracturing.
• Phase-boundary structures - study in detail structures that develop during dissolution-precipitation creep and other phase-transitions. These structures may be useful as stress indicators.
• Melt-solid reactions and associated structures - study melt solid reactions on the grain - scale to determine stabilties of wetting angles.
• Coupling between different processes during dynamic recristallization - determine deformation mechanism maps of different dynamic processes.
• Accumulation and self-organization in hydrofracture transport of fluids - study of highly dynamic fluid transport systems.
• Lithospheric scale models of rift segment interaction and rift flank uplift.
