摘要：
Positron lifetime spectroscopy was conducted for natural minerals to investigate open-nano pores. Positronium (Ps) formation occurs with ortho-positronium, (o-Ps) intensities ranging from a few % to 20 % and size distributions of nano pores are evaluated from o-Ps lifetimes. The results will be discussed with respect to formation processes of nano pores influenced by earth's environment.
