Heterogeneous ejection temperatures recorded in a “low-shock” Martian meteorite by (U-Th)/He thermochronology and a high-pressure phosphate polymorph

Key Points

• Heterogeneous ejection temperatures indicate complex geological processes on Mars, showcasing temperature variation.
• Key evidence showed temperatures ranging from 60 to 130 degrees Celsius, revealing how the meteorite formed over time.
• Analysis performed using U-Th/He thermochronology, focusing on a high-pressure phosphate polymorph present in the meteorite.
• These findings underline the significance of ancient Martian processes and highlight the potential for future exploration.
