Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another. This melting generates magma that makes its way to the surface ...

Mars’ thick crust may have been a hidden engine of geological activity, producing granitic magmas and sustaining underground water reservoirs. A new study suggests that radioactive heating in the plan ...

Over time, cooling-induced convection as well as partial melting have subsequently played a pivotal role in generating additional chemical heterogeneities in this vast reservoir. Formation of ...
