Crystalline Materials for Actinide Immobilisation
Self-irradiation provides equilibrium between two competing processes: gel
crystallisation largely into zircon and zircon metamictisation (Burakov et al., 2006)
. natural gels' high chemical durability is caused by two competing processes that
...

... conditions of the crystal lattice, e.g. the grade of metamictisation and therefore
the uranium content and the age of the mineral. The metamict crystal will lose
lead at fairly low temperatures, at which the lattice will be healed. Radiogenic
lead ...

Radioactivity in geology: principles and applications
The degree of metamictisation depends upon the number of a-particle sources in
the mineral, the strength of bonding, the openness of the structure and the
chemical stability of the mineral, a-particles may cause damage in crystal lattices

Berichte der Deutschen Mineralogischen Gesellschaft
The dependence of CL generation on the degree of metamictisation, however, is
not yet completely understood. In order to study the origin of CL in crystalline and
metamict zircon, we combined CL spectroscopic investigations on natural and ...

Radiogenic Isotope Geology
In other words, unaltered zircon lattices lose very little or no lead, whereas
altered zircon (promoted by metamictisation) loses lead very readily. Any given
zircon crystal may contain both kinds of material. For example, Fig. 5.7 shows
alteration ...
