| Description | Zirconolite, CaZrTi2O7, is a mineral with excellent resistance to hydrothermal alterations. It usually remains unaltered in geological environments for hundreds of millions of years or even longer periods despite of high contents of unstable elements like U and Th. For this reason synthetic analogue of zirconolite doped with components of spent nuclear fuel is suggested to be used as a form for immobilisation of high level nuclear waste. In this work we studied both the natural and experimental alterations of metamict zirconolites from Hakestad and Stalacker quarries in Norway in order to describe behaviour of this phase in contact with hydrothermal fluids – the mobility of elements and the alteration features. |
