| 摘要: |
| A study on the isotopic geochemical exploration in the yushui-yinsi copper and polymetallic mineralization belt,guangdong |
| 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. |
