Q Gases

Major part of ‘planetary’ Ar, Kr, and Xe. These components (labeled Ar-Q, Kr-Q, and Xe-Q) usually dominate Ar, Kr, and Xe in primitive meteorites. Q gases are isotopically heavier than solar wind gases and are most likely of ‘local’ origin (probably trapped in the solar nebula by an ill-defined carbonaceous carrier ‘phase Q’).
