| Abstract: | As viewed from a traditional consideration, ore-forming materials of the contact-metasomaticskarn-type Cu-Pb-Zn deposits are derived from magmatic differentiation. In this paper, based onthe comparison of ore lead isotopes with those of magmatic rocks and country rocks,the authorsproposed three types of ore-forming material sources for these deposits, i. e-, magmatic source,mixing source (magma and country rock)and multiple mixing source. |
