| 摘 要： | 对个旧锡矿床的铅、硫同位素进行了研究,研究结果表明,矿石中的铅、硫同位素主要来自基性岩,少量来自花岗岩,矿床的形成经历了印支期的基性火山成矿作用(铅模式年龄200-280Ma)和燕山期花岗岩的叠加改造成矿作用(铅模式年龄80-160Ma).进一步表明,个旧锡矿床为一个多成因多物质来源的矿床. |

| Abstract: | Lead and sulphur isotopes of Gejiu tin deposit have been studied.The results show that lead and sulphur isotopes in ores came mostly from basic rocks while some came from granite.Formation of the deposit underwent Indo-Sinian basic volcanic mineralization(mode age of lead isotope from 200 to 280 Ma) and Yanshanian granitic superimposition mineralization(mode age of lead isotope from 80 to 160 Ma).It is further proved that Gejiu tin deposit is a compound genesis type. |
| Keywords: | tin ore deposit lead isotope sulphur isotope Gejiu Yunnan province |
