| 中文摘要: |
| 山西堡子湾—九对沟金(钼)矿为一隐爆角砾岩型矿床,堡子湾金矿成矿与二长花岗(斑)岩关系密切,九对沟金钼矿成矿与流纹岩具成因联系。矿区硫化物δ34S值为-4%～+8‰,显示岩浆熔体硫同位素特征；与成矿具成因关系的二长花岗(斑)岩和流纹岩(成矿母岩)Sr-Nd同位素数据表明成矿岩浆来自EM1地幔源区。综合研究区H、O、Pb、Sr-Nd同位素以及稀土元素地球化学特征分析,推测该矿区成矿物质主要来源于I型富集地幔源区,在成矿过程中有壳源物质的加入。 |
| 英文摘要: |
| The Puziwan-Jiuduigou Au (Mo) deposit in Shanxi is a cryptoexplosive breccia type deposit. The Puziwan Au deposit has a close connection with monzonitic granite porphyry, and the Jiuduigou Au(Mo) deposit has a genetic connection with the rhyolite. The result of sulfur isotope in the ore district, δ34S Value ranges from -4‰ to +8‰, which shows the characteristic of sulfur isotope in magmatic system. The data of Sr-Nd isotope from the monzonitic granite porphyry and rhyolite, which has a genetic connection with mineralization, suggests that magma derived from EM1-type mantle. Comprehensive geochemical characteristics of hydrogen isotope, oxygen isotope, lead isotope, Sr-Nd isotope, and trace element from Puziwan-Jiuduigou Au (Mo) ore district, show that the ore-forming materials are mainly derived from EMI mantle, and contaminated by earth crust materials in the ore-forming process. |
