| 中文摘要: |
| 罗卜地斑岩体属钙碱性岩系、中酸性岩类,其岩浆属混源型,同位素地质年龄为52.76Ma.罗卜地斑岩体属同源同期多次序贯入侵位的复式岩体；成矿微量元素及矿化剂微量元素均具显着异常；爆破角砾岩及其相应的垂直裂隙发育。通过对罗卜地斑岩体岩石地球化学及其地质特征的综合分析研究,一致地表明罗卜地斑岩体为铜(钼)矿化类型斑岩体,具良好的成矿远景。 |
| 英文摘要: |
| Himalayan Luobodi porphyry bodies belong to calcc-alkali and intermediate-acidic rocks formed by crust-mantle magma.Isotopic dating is 52.76Ma, The porphyry bodies are multiplex and formed through repeated invasion in a stage by the same magma source with abnormal abundance of ore-forming elements. Dlasted breccia and relevant vertical fissure are developed. By synthetically studying on Luobodi porphyry bodies in geology, petrochemistry, trace element and so on, the paper concludes that Luobodi porphyry bodies belong to copper(molybdenum) por-phyry bodies,are potential for exploration. |
