To compare the sorptive properties of fracture-filling and other secondary minerals in the rock matrix, radionuclides representing the alkali metals ( 137 Cs). Alkaline earths ( 90 Sr), rare-earth elements ( 147 Pm), higher actinides ( 241 Am), and one anionic fission product ( 95m Tc) were sorbed on thin sections of rock containing fractures. The results indicate a general enhanced sorption by the secondary minerals compared to that of the primary minerals in the rock matrix.--Modified journal abstract.
