The lithium content was determined for some saline spring waters in Japan. The concentration factor of Li, C<sub>Li</sub>=(Li/Cl)<sub>sp</sub>/(Li/Cl)<sub>sw</sub> (sp=spring water, sw = seawater) was calculated and the dissolution experiments of Li-minerals in NaCl solutions were carried out to elucidate the enrichment of lithium in the waters. The concentration of chlorides and temperature of waters were proved to be important as the factors controlling the Li concentrations. It could be concluded from the relation between the values of C<sub>Li</sub> and C<sub>Mg</sub>, and from the results of dissolution experiments that lithium had been brought in the saline spring waters by the interaction of rocks or sediments with saline solutions such as seawater.
