| 中文摘要: |
| 成矿多样性是成矿事件的根本表现,反映在不同尺度水平和不同成矿属性特征上.文章分析了三江南段有色及贵金属矿床成矿多样性,揭示三江南段有色及贵金属矿产类型多、分布广,可划分为4个成矿区;成矿时代从新元古代到第四纪均有发生,并有由老而新不断增强的趋势,成矿作用高峰有两期:海西期和喜马拉雅期,其中最重要的成矿期是喜马拉雅期;矿床成因类型多样,不同成因类型矿产在不同的地质演化阶段规模不同.研究结果对指导三江南段找矿具有十分重要的意义. |
| 英文摘要: |
| Mineralization diversity, which reflected in the different levels and different scales mineralization identity characteristics, is an essential phenomenon in ore - forming process. The article analyzed the mineralization diversity of nonferrous and precious metal deposits in the southern Sanjiang, revealed nonferrous and precious metal deposits with different types and wide distribution. The deposits can be divided into mineralizing regions, Mineralization can happen from Neo -Proterozoic to Quaternary, and mineralizing intensity increased constantly from old to new. Mineralization has two periods, the Hercynian age and the Himalayan age, and the most important mineralization happened at Himalayan. Genetic types of deposits are various. Materializing scales of different type deposits in the different geological evolution are different. The results would is of great significance for ore - finding in the southern Sanjiang. |
