Rao --- Inhalt: englischer Text,  The results of an integrated study of physical and chemical properties of lunar samples returned to earth by the automatic Soviet stations Luna 16 and 20 carried out with a view to dilineate the evolutionary history of moon, are reported. The nature of the Luna 16 and Luna 20 landing sites and lunar samples, and the manner in which the integrated analyses were planned and executed, are discussed. It is noted that the two lunar missions have provided a wealth of new information in unravelling the early history of planetary formation. (A.K.) KK-PS22-5
