An outline is presented of lunar chronology and evolution based on analyses of the isotopic parent-daughter systems Rb-87-Sr-87, U-Th-Pb-206-Pb-207-Pb-208, and K-40-Ar-40. The samples which were investigated represent mare basalts (returned by Apollo 11, 12, 15, and 17 and by Luna 16) and terra rocks which include non-mare basalts, anorthosites, troctolites, and norites, but are predominantly comprised of complex breccias (returned by Apollo 12, 14, 16, and 17 and Luna 20)
