The isotope composition of xenon in the agglutinates, regolithic breccias, and a regolith sampled by Luna 24 spaceprobe from the Mare Crises area is investigated. Depending on the rock type, the concentration of Xe varied (in the range of 1.6 x 10 to the -8th to 2.3 x 10 to the -7th cu cm/g), being the lowest in the regolith and the highest in the regolithic breccias, in which Xe concentration was 2-14 times above that of the regolith. Evidence was found for the presence of captured cosmogenic Xe-126, indicating that the Xe delivered during meteorite impacts was absorbed and redistributed. Isotope analyses indicated that among the trapped Xe there was, in addition to the solar SUCOR-type Xe, an anomalous type of Xe enriched in Xe-136, Xe-134, Xe-132, and Xe-130.
