Abstract

In order to investigate the structural evolution and the capability of resistance to -ray irradiation of natural minerals, the zircon from metamorphic rock in the middle region of Hainan was investigated. The morphologic characteristic of cracked rocks was observed and zircon crystals were selected under a multifunctional microscope. All the samples were irradiated using a 60Co -ray source to 576 kGy. Phases and structures of the as-gained samples were characterized by X-ray diffraction (XRD) and Raman spectroscopy (Raman) before and after -ray irradiation. Moreover, the chemical compositions of zircons were analyzed by electron probe micro-analyser (EPMA) as well. The results show that the as-gained crystals which come from metamorphic rock undergone near 1483 million years geological evolvement and still contained UO2 and ThO2 with the contents of 0.3074 wt%. In addition, the samples had good crystallinity. No obvious damage to the structure is found in the zircon irradiated by -ray with 576 kGy, however the disorder degree of crystal has a slight increase.
