Abstract

Dolerite samples taken from Sandford Cliffs, Antarctica were used as meteoritic analogues for cold desert residence and studied to investigate subsequent alteration of noble gas inventories. The ⁸⁴Kr/¹³²Xe and ³⁶Ar/</sup>132Xe ratios were seen to decrease with increased amounts of weathering, the δ¹⁵N showed little change. The most weathered dolerite showed a signature close to Martian interior.
