Inheritance control on tectonic plate boundaries

Tectonic plate boundaries are constantly (re)used to assemble and breakup supercontinents through geological time. This is known as the Wilson Cycle, a concept that describes how sutures and mountains are reactivated to open oceanic basins, which are in turn subducted leading to continental collision and the rise of orogenic belts. The successive rifting and shortening events modify the lithosphere along plate boundaries with structural, compositional, and thermal heterogeneities. In each tectonic event, these inherited heterogeneities are considered to play a key role in localizing strain, defining the structural style, the magmatic budget, and the final architecture of the crust. Thus, elucidating the structural and rheological nature of the heterogeneities and how they interact with far-field tectonic forces to localize deformation remains a key component of interpreting both active and prior deformation patterns.
In the session we welcome contributions that use field observations, geophysical data, analogue and/numerical modelling to investigate all aspects of inheritance and how it controls the tectonic processes involved in shaping convergent and divergent plate boundaries. We are interested in studies that examine deformation across a wide range of spatial and temporal scales (microstructural- to lithospheric-scale), and address the impact of inheritance through structural, geophysical, experimental, or computational approaches.
