16. Mössbauer spectroscopy under high pressures and temperatures
Abstract : Iron plays a very important role in Earth materials. 57Fe- Mössbauer spectroscopy provides valuable information on the oxidation state and the near surrounding of iron atoms in crystal structures. READ MORE

17. Diagenesis and Sequence Stratigraphy : an integrated approach to constrain evolution of reservoir quality in sandstones
Abstract : Diagenesis and sequence stratigraphy have been formally treated as two separate disciplines in sedimentary petrology. This thesis demonstrates that synergy between these two subjects can be used to constrain evolution of reservoir quality in sandstones. READ MORE

18. Thin sheet approximations for geodynamic applications
Abstract : Thin sheet approximations are widely used in geodynamics because of their potential for fast computing of 3D lithospheric deformations using simple numerical techniques. However, this simplicity imposes limits to boundary conditions, rheological settings and accuracy of results. READ MORE

19. The West Ny Friesland Terrane : An exhumed mid-crustal obliquely convergent orogen : by Patrik W. Nilsson
Abstract : Ny Friesland, in northeastern Svalbard, is the type-area for transpressive orogeny. The West Ny Friesland Terrane (WNT) is composed of a c. 12 km thick basal succession of amphibolite-grade schists and gneisses, previously thought to be the lower of a c. 20 km thick succession of concordant, volcano-sedimentary strata.

20. Deformation zones in models and nature
Abstract : Field studies encounter several complicating factors not studied in the models. Examples are oblique convergence, heterogeneous materials and thermal softening by intruding magmas. READ MORE
