| 中文摘要: |
| 黄铁矿是地壳分布最为广泛的金属矿物，其Re-Os同位素体系在金属矿床成矿年代和示踪成矿物质来源研究中具有重要地质意义。文章简述了Re-Os同位素体系成矿定年和示踪成矿物质来源的基本原理，综述了近些年黄铁矿Re-Os同位素体系在金属矿床研究应用中取得的成果；认为该方法具有测试样品易选择、测试方法多样性等特征，但该方法目前尚存在黄铁矿样品选择的多样性、测试标样不成熟和分析结果误差较大等不足之处，有待进一步研究。 |
| 英文摘要: |
| Pyrite is the most widely distributed crustal metallic mineral. Its Re-Os isotopic system is significant geologically to determine the ore-forming age and trace ore material sources. This paper describes the basic principle of age-dating and the ore material tracing of the Re-Os isotopic system and reviews the recent achievements of pyrite Re-Os isotopic system application to study on metal deposits. The Re-Os isotopic system is characterized by easy selection of the test sample and diversity of test methods. However, the defact is diversity of sample selection of pyrtie and impaturity of the test sample and bigger erro of the analytical result thus should be furtherly improved. |
