Highlights of a first effort in sorting out rare gases in lunar material are solar wind rare gases in abundance; variable 20Ne/22Ne but constant 21Ne/ 22Ne ratios in fractions of the trapped neon; cosmogenic rare gases similar to those found in meteorites, except for copious 131Xe in one rock but not in another; at Tranquillity Base a rock 4.1 x 109 years old which reached the surface 35 to 65 million years ago, amid soil whose particles have typically been within a meter of the surface for 109 years or more.
