== Models of subduction polarity reversal ==

Even though many geologists agree that after the involvement of buoyant [[continental crust]], subduction polarity reversal may occur, they have different opinions towards the mechanisms leading to the change of subduction direction. Thus, there is no single model to represent subduction polarity reversal. How geologists develop the models depends on the parameters they focus on.<ref name=":142" /> Some geologists attempt to construct models of subduction reversal through laboratory experiments<ref name=":113" /><ref name=":322"/><ref name=":23" /> or observations.<ref name=":132222"/><ref name=":103" /> There are three common models: [[#Slab break-offdetachment|slab break-off]],<ref name=":132222" /> [[#Double convergence model|double convergence]]<ref name=":103"/> and [[#Lithosphere break-up|lithospheric break-up]].<ref name=":113" />

The models of slab-break up<ref name=":132222" /> and double convergence are based on observations by geologists,<ref name=":103"/> and the lithosphere break-up model is based on experimental [[simulation]].<ref name=":113" />
