Rb-Sr systematics of Luna 20 and Apollo 16 samples
Abstract
Lunar soils from all missions indicate that an early lunar differentiation process occurred in the interval 4.3-4.6 AE and resulted in the formation of a crust rich in K, Rb, U and Th. An attempt has been made to identify rocks which were formed during this early differentiation event.
