| 中文摘要:文章总结了大量的Sr，Nd，S，Pb多元同位素资料，据此认为，中亚造山带的铜、金多金属矿床与区域花岗岩在形成时代和物质来源上基本吻合，具有一定的继承性。从古生代直至中生代，地幔来源物质参与了成岩成矿作用，即便是钨、锡、稀有金属矿床，也受到地幔来源物质的明显影响，从而揭示了地幔来源物质在中亚造山带金属成矿作用中的重要意义。 |

| Abstract:The Central Asian Orogenic Belt (CAOB) is one of the most important regions for Cu, Au and polymetallic as well as rare metallic (Li,Be,Nb,Ta) mineralizations in the world. Sr, Nd, S and Pb isotopic data available indicate that the mineral deposits of the CAOB are consistent with the regional granites in metallogenic epochs and sources. Data available also suggest that mantle sources might have played an important role in the Paleozoic to Mesozoic mineralization in the CAOB. |
