The relationship between mantle potential temperature and oceanic lithosphere buoyancy

Abstract:

The Earth's mantle potential temperature (TP)is thought to have cooled by ∼250 ∘C since the Archean, causing a progressive change in both the structure and composition of oceanic lithosphere. These variables affect the negative buoyancy of subducting slabs, which is known to be an important force in driving plate motions. However, the relationship between TP and slab buoyancy remains unclear. Here, we model the formation and subduction of oceanic lithosphere as a function of TP, to investigat...
