Metamictisation

Metamictisation (sometimes called metamictization or metamiction) is a natural process resulting in the gradual and ultimately complete destruction of a mineral's crystal structure, leaving the mineral amorphous. The affected material is therefore described as metamict. Metamict minerals can have their crystallinity and properties restored through prolonged annealing.
