We measured the isotopic abundances of the noble gases in bulk samples and grain-size separates of lunar meteorite Yamato-793274. The presence of relatively high contents of trapped solar wind gases and stable cosmic-ray produced nuclei indicates that Y-793274 consists of submature lunar regolith ma...
