DeepDyn | Radiative heat transport across the core-mantle-boundary: GFZ

Radiative heat transport across the core mantle boundary | Transparent_Opaque

The DFG-funded SPP 2404 unravels how the long-term evolution of the lower mantle and core affects the geodynamo. (https://www.geo.lmu.de/deepdyn/de/)

How transparent is the Earth’s lowermost mantle? How significant is radiative heat transport at the core-mantle boundary?

Heat flow out of the Earth’s core fuels many planetary-scale geological processes. The main goal of this project is to quantify the radiative contribution to the total thermal conductivity at the base of the mantle. To this end, we perform time-resolved spectroscopic experiments in laser-heated diamond anvil cells. Our results will help constrain heat flux patterns across the CMB, which is a key to linking deep mantle structures, their dynamics, and geodynamo. This project is part of the DFG SPP DeepDyn.
