Results of INAA for samples from the 76001 drive tube

Concentrations of 24 chemical elements obtained by instrumental neutron activation analysis (INAA) in regolith samples taken at half-centimeter dissection intervals (N=62) of the 76001 drive tube (31 cm) taken at station 6 (North Massif) of the Apollo 17 landing site. Concentrations of 23 chemical elements obtained by instrumental neutron activation analysis (INAA) on fines (<0.25 mm) and lithic fragments (0.1-3.9 mg each) from regolith samples collected on the Luna 16 (N=23), Luna 20 (N= 33), and Luna 24 (N=18) missions.
