Ancient Martian Meteorite Unveils Secret
A new study has revealed that the ancient Martian meteorite, known as NWA 13441, discovered in Algeria and estimated to be about 1.273 billion years old, represents the earliest analyzed sample of Shergottite rocks to date. This discovery is significant because it sheds light on a time period that is underrepresented in the Martian rock record, providing direct evidence of volcanic and magmatic activity during an era previously little understood. Additionally, analysis showed that the magma from which the rock formed originated from a new, previously unknown reservoir deep within Mars. This reservoir bears a unique isotopic signature indicating that its chemical composition dates back to the initial stages of the solar system's formation, deepening scientists' understanding of Mars’ internal history, its diversity, and its geological evolution over billions of years.
