Abstract
Understanding the stability of radiation-damaged zircon is crucial to the application of zircon to U-Pb geochronology, especially for zircons rich in radioactive nuclides. Electron microprobe and laser Raman spectral analyses show that zircons from the Ejinao sodalite syenite in Southeast China are composed of cores without zonation and oscillatory rims. The cores are rich in uranium and have experienced increased metamictisation. An internal sieved structure and radial cracks were formed by radiation damage and radiation-induced volume expansion. Infrared spectral analyses show that zircon from the Ejinao sodalite syenite contains large amounts of OH and H2O. This finding suggests that the zircon crystals experienced hydrothermal alteration.
