In continuation of our work about springs in the São Paulo State, this paper has the finality to analyse, from the chemical and geological point of views, the sources of waters in the region of Aguas de Lindóia. A totality of 26 springs has been studied, all belonging to the crystalline complex of metamorphic rocks known under the name of Amparo gneisses. All of these springs are of feeble discharge with exception of those of the "Balneário de Aguas de Lindóia" which are also hypothermal. From the chemical viewpoint, all waters have similar characteristics as much in major elements as in trace elements. Accordingly to their composition, they can be classified as bicarbonated sodic, calcic and magnesian waters. Some of them is mixed or chloro-sodic. Only the radioactivity at the spring permits to consider them as mineral waters, having in view their low concentration in dissolved solids.Resumo indisponível.
