Seismic detection of a deep mantle discontinuity within Mars by InSight

by cbegheinNewsPosted on Comments are Disabled

The paper “Seismic detection of a deep mantle discontinuity within Mars by InSight” led by Quancheng Huang is out! Summary: The depth and sharpness of a midmantle seismic discontinuity, associated with the phase transition from mineral olivine to its higher-pressure polymorphs, provide essential clues to understanding the temperature and composition of Martian mantle. Using data …
