It is becoming increasingly apparent that Wilson Cycle processes (i.e. processes controlling rifting, drifting and inversion) involve complexities not easily explained by standard models, especially in oblique and transform settings. In rifted margins, oceans and orogens, abundant data showcases the significance of inherited geological structures, lithospheric rheology, time-dependence, surface processes, magmatism, obliquity, and geometry in processes of rifting, drifting and inversion, yet our understanding of the role and interaction of these factors remains far from complete. Unexpected discoveries, such as continental material far offshore (e.g. at the Rio Grande Rise) and wide-magmatic rifted margins (e.g. the Laxmi Basin), challenge conventional models and exemplify the need for further work on Wilson Cycle processes. This session aims to bring together new observations, models, and ideas to help us understand the complex factors influencing rifting, drifting, and inversion, at orthogonal, oblique and/or transform settings. Works investigating time-dependence, inheritance, plate kinematics, strain localisation, magmatism, obliquity, interior plate deformation, driving forces, sedimentation, surface processes, and the interaction/feedback between processes controlling the Wilson Cycle are therefore welcomed to this session. Contributions from any geoscience discipline, including geophysics, marine geophysics, seismology, ocean drilling, geochemistry, petrology, plate kinematics, tectonics, sedimentology, field and structural geology, numerical and analogue modelling, or thermo and geochronology etc., are sought. We particularly encourage cross-disciplinarity, innovative studies, the spanning of spatio-temporal scales, and thought-provoking ideas that challenge conventions from any and all researchers.

Solicited speakers for this session are Pauline Chenin and Gianreto Manatschal.
