Abstract
X-ray fluorescence analysis using synchrotron radiation (SRXFA) has be en applied for determination of trace elements in the highland lunar r ocks (Luna 20 and Apollo 16). On the basis of the distribution of Rb, Sr, Y, Zr, and Nb in 69 lunar highland fragments six geochemical group s of rocks with various aluminium and trace element contents were dist inguished for each station. They have various levels of trace element content. This suggests the various petrological processes: cumulation of rock-forming minerals and partial melting of source rocks. The last process lead up to enriching in trace elements in rocks formed from t hese melts. The distribution of trace elements in highland and mare ro cks of the Moon were compared.
