Summary:Quantitative and qualitative estimates of concentrations of various elements and isotopes in anorthosites of the Dzhugdzhur pluton and associated rocks were obtained by NAA. These data were compared to those from other terrestrial and lunar basalts and anorthosites and allowed a test of the hypotheses on magmatic origin to be made. Results clearly revealed the position and relationships of main rock types in the Dzhugdzhur pluton, best explained by assuming a magmatic origin of anorthosite material, which in magmatic chambers may become differentiated with a decrease in T. Observed Au and RE concentrations suggest that the melt originated from material which, at the depths at which melts were formed, differed from lunar rocks. [W.J.F.]
