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.
