Structural change of minerals in weathering and alteration processes at the surface of the crust is one of the important topics in earth science. In order to reveal its basic mechanisms, transmission electron microscopy (TEM) with atomic resolution is effective. Some examples related to alterations of micas are demonstrated in this paper. One of the obstacles to investigate these hydrous minerals, electron radiation damage, is being solved by new image recording systems, imaging plates and sensitive CCD cameras.
