Silicon oxynitride, a new mineral, has been discovered in the Jajh deh Kot Lalu enstatite chondrite. Nitrogen and oxygen have been measured quantitatively with an electron microprobe by means of prototypes of newly developed curved crystal detection systems. X-ray diffraction patterns were obtained from silicon oxynitride separated from the meteorite and from synthetic Si2N2O.
