Geological and isotopic evidence from Martian meteorites and thermal modeling supports the conclusion that the Martian mantle is heterogeneous and shaped by active mantle convection processes.

The analysis

Papers [0] and [6] directly discuss mantle convection, partial melting, and geochemical heterogeneities within the Martian interior, directly supporting the claim.

The paper notes that the presence of distinct volcanic provinces and specific Hf-isotope compositions indicate a primitive and convecting mantle reservoir alongside deep-seated mantle plumes on Mars.
