Chemical studies of Apollo 16 and 17 samples

Instrumental neutron activation analyses were conducted to nine Apollo 16 samples and 23 Apollo 17 samples. Radiochemical neutron activation analyses were carried out in the case of six Apollo 16 boulder-2 rocks, five Apollo 17 soils, and one Apollo 16 soil. The elemental abundances obtained are presented in tables and the significance of the analytical results is discussed. Attention is also given to interelement correlations.
