Studies concerning Rb-Sr isotopic relations are discussed together with abundance measurements regarding K, Rb, Sr, and Ba in Apollo 14 and 15 rocks and soils. The studies include age determination by the internal isochron technique on one basaltic rock sample from each of the two missions. In addition, total sample measurements have been made on samples of fines material from both missions. Trace element abundances and Rb-Sr systematics in the various grain size fractions of three of the fines have also been analyzed.
Apollo 14 and 15 samples - Rb-Sr ages, trace elements, and lunar evolution.
