摘要
本文以铅同位素组成为线索，讨论了与中酸性侵入岩有关的接触交代矽卡岩型铜铅锌多金属矿床的矿质来源，得出了该类矿床矿质的岩浆源、岩浆与围岩混合源及多源混合源三种来源。
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.
