| 中文摘要:玉水-银屎铜多金属矿带是粤东北重要的铜、铅锌、金、银等多金属成矿远景区（带）之一。已发现铜、铅锌、金、银、铁、锰等矿床、矿点多处，其中玉水铜矿、银屎铅锌矿是近几年发现并评价的富铜、铅锌中型矿床，在这两个矿床的外围还有若干矿点及异常区。本文应用铅、硫及碳氧同位素示踪，对玉水-银屎矿床及其外围若干矿点及远就（异常）区进行对比研究，在阐明矿床成因、物质来源、成矿时代、演化历史的基础上，总结已知矿床和矿点的同位素特征，提出找矿评价的稳定同位素标记，对远景区（异常区）进行找矿评价。 |

| Abstract:The “target practice”is made by using 206Pb/204Pb and 206Pb/207Pb ratios as the exploration markes.After the determination of standard target value of the Yushui copper deposit and Yinsi leadzine deposit,the isotopic exploration assessment is made in the abnormal areas outside the deposits inclusing Baiwa,Kuiling,Qianshanli and Fenshui ect.3-4 praspective exploration target areas are seleted as faverable areas.In the light of the lead isotopic characteristics,couplod with the field observations,the 206Pb/204Pb and 206Pb/207Pb ratios of the Baiwa and Kuiling are essentially consistent with the values of Yushui copper deposit and are the most proising areas for finding the Yushui type copper deposit.The lead isotopic composition of the Qianshanli just fall in the vange of the values of the Yinsi Pb-Zn deposit and is the promising areas for finding Yinsi type Pb-Zn deposit.The lead isotopic composition of the Fnshui area lies between the values of the Yushui and Yinsi,therefore is the most promising area for maybe finding the deposit with the characteristics of both Yushui and Yinsi deposits. |
