Fe-rich smectite is a clay mineral commonly found on Mars, particularly in the lowest
stratigraphic sequences. The presence of smectite is of interest because of its implications …

Transmission electron microscopy linked with energy-dispersive X-ray spectroscopy (TEM-
EDX) was applied to characterize mineralogical signals of weathering processes in the Di …

Bentonite is the candidate buffer and backfill material in the deep geological repositories.
Montmorillonite (Mt) is the major clay minerals of bentonite. Over a long period of time, the …

Radioactive waste is usually sealed in steel canisters surrounded by a layer of compacted
clay back-fill, and permanent buried in a deep geological repository. Unavoidably, the …

We investigated the chemical and mineralogical characteristics of a weathering profile of the
Nui Nua serpentinized ultramafic-mafic massif (Thanh Hoa Province, Vietnam) using TEM …

Bentonites are suitable candidates as buffer and backfill materials in HLW-repositories. A
target of this research is to define the mineralogical alteration of bentonite caused by its …

Because of their isolating capacity, smectite-rich clays have been proposed as buffer and
backfill materials in high-level radioactive waste repositories. These repositories have to …
