Short summary
Short summary
Extension leading to the formation of ocean–continental transition can be highly oblique to the main direction of crustal thinning. Here we explore the case of a continental margin exposed in the Betics that developed in a back-arc setting perpendicular to the direction of the retreating Gibraltar subduction. We show that transtension is the main mode of crustal deformation that led to the development of metamorphic domes and extensional intramontane basins.

Short summary
Short summary
Continental rifts form by linkage of individual rift segments and disturb the regional stress field. We use analog and numerical models of such rift segment interactions to investigate the linkage of deformation and stresses and subsequent stress deflections from the regional stress pattern. This local stress re-orientation eventually causes rift deflection when multiple rift segments compete for linkage with opposingly propagating segments and may explain rift deflection as observed in nature.

Short summary
Short summary
This study investigates one of the key processes that may lead to the destruction and destabilization of continental tectonic plates: the infiltration of buoyant, hot, molten rock (magma) into the base of the plate. Using simple calculations, I suggest that heating during melt–rock interaction may thermally perturb the tectonic plate, weakening it and potentially allowing it to be reshaped from beneath. Geochemical, petrologic, and geologic observations are used to guide model parameters.

Short summary
In this study we present a method to compute a reference pressure based on density structure in which we cast the problem in terms of a partial differential equation (PDE). We show in the context of 3D models of continental rifting that using the pressure as a boundary condition within the flow problem results in non-cylindrical velocity fields, producing strain localization in the lithosphere along large-scale strike-slip shear zones and allowing the formation and evolution of triple junctions.

Short summary
The local topographic slope of an accretionary prism is often used to determine the effective friction on subduction megathrust. We investigate how the brittle–ductile and the smectite–illite transitions affect the topographic slope of an accretionary prism and its internal deformation to provide clues to determine the origin of observed low topographic slopes in subduction zones. We finally discuss their implications in terms of the forearc basin and forearc high genesis and nature.

Short summary
Knowledge about the stress state in the upper crust is of great importance for many economic and scientific questions. However, our knowledge in Germany is limited since available datasets only provide pointwise, incomplete and heterogeneous information. We present the first 3D geomechanical model that provides a continuous description of the contemporary crustal stress state for Germany. The model is calibrated by the orientation of the maximum horizontal stress and stress magnitudes.

Short summary
Short summary
The borders between oceans and continents, called margins, can be convergent, divergent, or horizontally sliding. The formation of oceans occurs in a divergent context. However, some divergent margin structures display an accommodation of horizontal sliding during the opening of oceans. To study and understand how the horizontal sliding part occurring during divergence influences the margin structure, we performed 3D high-resolution numerical models evolving during tens of millions of years.

Short summary
We constructed a three-dimensional numerical geomechanics model to obtain the continuous slip rates of active faults and crustal velocities in the northeastern Tibetan Plateau. Based on the analysis of the fault kinematics in the study area, we evaluated the possibility of earthquakes occurring in the main faults in the area, and analyzed the crustal deformation mechanism of the northeastern Tibetan Plateau.
We constructed a three-dimensional numerical geomechanics model to obtain the continuous slip...
