✦ Synopsis
The role played by the petrophysical characteristics of the rock matrix in the radioelement transfer phenomena through the geosphere is considered. The aim of this paper is to correlate information provided by the microcrack network, mineralogy and U-micromapping studies which can be used to quantify the extent of radioelement migration/retention in the granite. The experimental procedure combines complementary microscopic techniques. Data on preferential fissure zones in relation to mineralogy, and the correlation between these data and uranium microdistribution are obtained. These results are discussed in terms of radionuclide mobility and can be used for evaluating the retardation capacity of the crystalline rock matrix around a high-level radioactive waste repository.
