True and Apparent Polar Wander From Sluggish to Active Lid Tectonics
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.Abstract It has been proposed that to satisfy a wide range of geological observations, early Earth mantle convection operated in “sluggish‐lid” tectonics before transitioning to modern‐day, “active‐lid” tectonics. The former is the result of a weaker asthenosphere relative to the latter and manifests itself in a partially decoupled plate‐mantle system.

Journal of Geophysical Research: Planets, Volume 130, Issue 9, September 2025.Abstract We present a comprehensive study of a new Martian meteorite, Northwest Africa (NWA) 16788, found in the Sahara Desert in July 2023. This specimen constitutes the largest known individual meteorite of Martian origin, with a total weight of ⁓25 kg. A detailed mineralogical and geochemical investigation identifies NWA 16788 as an enriched olivine
