| contents | The Wilson Cycle, a fundamental paradigm in plate tectonics, describes the episodic opening and closing of ocean basins and supercontinent assembly and dispersal. While driven by mantle convection, the specific mechanisms linking deep mantle processes to surface plate motions, particularly the initiation and termination of subduction, remain subjects of active research. This paper proposes that the subduction engine, characterized by the dynamic interaction between subducting lithospheric slabs and the ambient mantle, plays a pivotal role in orchestrating the various stages of the Wilson Cycle. We explore how slab pull, slab resistance, slab rollback, and slab stagnation modulate mantle flow patterns, induce trench migration, influence continental rifting, and facilitate arc magmatism. Through a synthesis of geophysical observations, geodynamic modeling, and geological evidence, we elucidate the feedback loops between slab dynamics, mantle rheology, and surface plate kinematics. Understanding these intricate interactions is crucial for a comprehensive appreciation of Earth's long-term tectonic evolution. |
