Abstract

Slab dynamics poses a critical hurdle for understanding mantle convection and plate tectonics on Earth in general and subduction zone processes, such as intraslab earthquakes, mantle wedge flow, and volatile recycling, in particular. A significant effort has been made for the development of a series of numerical and analog experiments and the synthesis of observational constraints on slab dynamics. This chapter is dedicated to guiding the reader through the current state of our knowledge and some of the long-standing and recently raised questions that resulted from these studies.
