摘　　要： The geographical distribution and physical properties of Qionglei tektites from South China are described in the present paper. 12 samples of Qionglei tektites have been determined for major and minor elements such as A1; Ba, Ce, Co, Cr, Cs, Eu, Fe, Gd, Hf, La, Mg,Na, O, Rb, Sb, Sc, Si, Sin, Ta, Tb, Th, U, Yb, etc. by NAA techniques. The family to which the tektites belong correlations between main oxides and SiO2, relative REE abundances, REE distribution patterns, Th/U ratios, and their bearing on the evolutionary history and genesis of Qionglei tektites are also discussed.
