35695 abstract Apatites in low-Ti mare basalts from the Apollo 15 landing site display a large range of OH content from about 100 ppm up to ~ 2000 ppm. The D/H ratios measured in these apatites yielded δD values of ~ 550-1050 ‰. On the other hand, apatites in the KREEP basalt 15386 have less than 250 ppm OH and yielded δD values in the range ~ 20-500 ‰. These data suggests that the source of KREEP basalts was much drier than the mare basalt mantle sources, implying a late addition of H-bearing species into the mare source regions.
