A Martian meteorite found in Algeria (NWA 13441) has been dated to about 1.27 billion years old, filling a nearly 2-billion-year gap in Mars’ geological history and offering clues about volcanic activity and deep Martian reservoirs that remained relatively unaltered in that era.
A Martian meteorite found near Rafsa, Algeria (NWA 13441) has been dated to 1.273 ± 0.021 billion years using samarium-neodymium isotopes, placing it in a long gap for shergottites between about 600 million and 2.4 billion years ago. The date is a crystallisation age on Mars, not the time of ejection or Earth arrival, and while it reveals a previously unsampled window in Mars’ magma history, it does not rewrite the planet’s entire history.
