| Abstract: | The dynamo explanation of Mercury's magnetic field leads to constraints on the thermal evolution of the planet. A heat-source density at least comparable to the Earth's mantle-wide average must have been retained throughout Mercury's mantle, if the core is still molten, and if Mercury's mantle possesses rheological properties similar to those of the Earth's upper mantle. |
