We observed adsorption structure of cesium in weathered biotite, illite and pyrophyllite by using XAFS technique. In case of weathered biotite and illite which incorporate cesium ions into interlayer site, the interatomic distances of second coordination are decrease at low concentration samples. On the other hand, pyrophyllite which doesn't incorporate cesium ions into interlayer site, has no concentration dependence of the interatomic distance of second coordination.
