Study Uncovers Evidence of Mars’ Turbulent Early History in Mantle

Fast Summary

• NASA’s InSight mission has provided seismic data revealing Mars’ mantle contains ancient fragments preserved from its violent early history.
• mars’ mantle lies between its crust and core and offers critical information about planetary formation and evolution.
• Unlike Earth, which has active plate tectonics, Mars features a single-plate surface allowing less mixing in the mantle.
• Researchers analyzed eight marsquakes to study delayed high-frequency P-waves in the deeper portions of the Martian mantle, showing kilometer-scale compositional variations.
• These variations are remnants of early planetary impacts that fractured the interior and mixed foreign materials into Mars’ mantle during a global magma ocean phase.
• The crystallization process after these impacts froze chaotic features as convection slowed beneath Mars’ stagnant lid crust.
• Findings suggest fractal distributions caused by energetic planetary collisions can persist for billions of years without erasure.
