In order to characterize water/rock interactions of granite, we performed laboratory experiments and Pb-Li isotopes tracing. The aim of the present work is to better constrain the processes of water/rock interactions both in terms of source and extent of weathering, by measuring major and trace elements as well as Pb and Li isotope signatures.
