Tectonic models represent hypothesised approximations of past geological events that best fit and explain a pre-defined collection of data points. Incorporation of geological observations with an understanding and consideration of geodynamic concepts, geological processes, and physical properties of geological materials ensures that empirical models are consistent with physics and mechanics, and that numerical models are consistent with field observations and petrological constraints. Integrating these constraints and concepts within a plate kinematic framework that considers the size, distribution and past and present motions of tectonic plates ensures that models are consistent with global plate tectonics. Incorporating this information with interpretations of the distribution of subducted slabs and plumes in the upper and lower mantle allows for construction of tectonic models that consider the global tectonic-mantle system. We welcome state-of-the-art, multi-disciplinary, and multi-scale studies that combine geological and geophysical constraints from the bedrock record with interpretations of deep mantle structure and/or plate kinematic datasets to investigate geodynamic events of past and present. These may include, but are not limited to studies of rifting and ocean spreading, subduction, orogeny and terrane accretion, and dynamic topography. We expect this session to include a diverse range of multi-disciplinary studies united by a common goal of understanding the geological evolution of our planet’s tectonic-mantle system.
