Webboundaries and hotspots) temperature increases at a rate of 25-30°C per km in the lithosphere. The kink in the geothermal gradient indicates the lithosphere-asthenosphere boundary which occurs at ~1300°C. For rocks to melt the geothermal gradient (or geotherm) must cross the solidus (blue line). The solidus marks the transition from solid WebThe temperature gradient within the lithosphere varies depending on the tectonic setting. Gradients are lowest in the central parts of continents, higher where plates collide, and … WebThe temperature gradient for adiabatic compression (i.e., the change of temperature due to a change of pressure alone, without exchange of heat with its invironment) is much smaller than the gradient in the conducting thermal boundary layer. 2.
