Remanent crustal strain on Mars in non-poikilitic olivine of NWA 7721
The paper 'Remanent crustal strain on Mars in non-poikilitic olivine of NWA 7721' examines how internal stresses survived a massive impact. Researchers analyze the rock's bimodal microstructure, concluding that pre-existing geological stress was not erased by the collision. This provides a detailed record of Mars' dynamic history.
