In-Situ (U-Th)/He Dating of Martian Apatites: Low-Temperature Thermal Processes in the Late Amazonian Martian Regolith Recorded by NWA 7034

Apatite – Ca5(PO4)3(OH,F,Cl) – is a common accessory mineral in many terrestrial rocks and has a low (~75˚C) closure temperature for He retention[1]. As such the (U-Th-Sm)/He thermochronometer has ...
