Temperature and potential temperature beneath island arcs
Abstract
Potential temperature within a convecting fluid is a useful concept if the distance which heat diffuses in the time taken for the material to overturn is appreciably smaller than the scale height. This condition is satisfied within the mantle, and therefore the equation governing the conservation of energy may be simplified by using potential temperature. The resulting equation can be solved analytically to obtain the actual temperature distribution within the sinking slab beneath island arcs.
