| Abstract: | The amount of trapped inert gases present in rock 66095, as well as the elemental and isotopic composition of these gases can be explained by “contamination” of this rock - on the lunar surface - with as little as 0.2% of fines There is no compelling evidence that these gases come from the impact of a comet or a carbonaceous meteorite on the Moon, or that they represent genuine primordial lunar gas.The21Ne radiation age of 66095 is (1.1 ± 0.5) × 106yr, which strongly suggests that this rock was excavated by the South Ray Crater event. |
