Fluorine (by combined distillation‐spectrophotometry) and chlorine (by X‐ray fluorescence spectrometry) contents were determined in normal and Muong Nong‐type tektites. Contents of F (78–285 ppm) and Cl (3–44 ppm) in normal tektites are about 4 and 10 times lower, respectively, than in the Earth's continental crust and this is attributed to selective volatilization during impact melting. Muong Nong‐type tektites are characterised by similar F (124–312 ppm) but higher Cl (65–205 ppm) contents and may have resulted from a lower temperature event.
