New data on the chemistry of lunar samples: primary matter in the lunar highlands and the bulk composition of the moon.
Abstract
New data were obtained on all major and minor elements and a large number of trace elements of five Apollo 15, eight Apollo 16, and eight Apollo 17 samples. Up to 55 elements were determined in individual samples. For major elements both X-ray fluorescence and activation methods with 14 MeV and thermal neutrons were applied. With 14 MeV instrumental neutron activation analysis direct data on oxygen and a number of trace elements were obtained (Zr, Y, Nb, and Ni). In addition to the major elements, P, S, and Ni were also determined with X-ray fluorescence. The results are presented in four tables. With the exception of some basalts from and around Mare Imbrium all mare basalts show reasonable correlation with a Na/Eu ratio of about 1500.
