摘要：

The damage in zircon structure is caused by α-decay which is associated with radiation of uranium and thorium in zircon. Over the narrow dose range from 0.3×10to 0.8×10α-events mg, natural crystalline zircon begins to convert to metamict state. When α-decay dose reaches 0.8×10α-events mg, the crystalline zircon would be changed to completely metamict state through several million geological years, and the metamict state zircon ap-
