El sistema granito-mineralización de uranio de El Berrocal como análogo natural de un almacenamiento de residuos radiactivos

Abstract

This work summarizes the analogical study of the radioactive elements and rare earths are deposits applied to the modelling and validation of the migration/retention processes of the high level radioactive artificial isotopes in a geological environment.

The geological, mineralogical and geochemical characteristics of the El Berrocal granite- U mineralization system suggest that this system cannot be considered as a global natural analogue for a radioactive waste repository. However, the low-temperature hydrothermal processes, which affected it, including that one which originated the uraniferous mineralization, as well as the weathering processes, can be considered as geochemical processes analogous to those that could take place in a high level radioactive repository.
