Hydration states and dehydration reactions within mantle minerals modify thermal conductivity and control heat transport processes in Earth's interior.

The analysis

The retrieved papers provide solid empirical and mineral physics evidence that water content, hydration, and dehydration reactions significantly affect thermal conductivity and heat transport mechanisms in Earth's interior (such as within subducting slabs and the mantle transition zone).
