This paper considers the geological characteristics and stable isotopic compositions of sed-imentary-reformed Pb-Zn deposits of China, the physical and chemical properties and sourcesof reformed fluids, and the experimental studies of migration and deposition of Pb and Zn inthem. It is suggested that after ore substances were synchronously deposited with source beds,they were reformed through later geological events, thus making the sedimentary deposits fur-ther enriched. There is no obvious genetic relation between ore formation and magmaticactivity.
