| 摘 要： | 熔体包裹体由被封存在矿物中的原始岩浆组成,有效的保存了有关其主矿物形成时周围岩浆介质的物理化学信息,是研究岩浆演化和成矿作用的原始样品。本文以内蒙古巴尔哲超大型稀有稀土金属矿床中伟晶岩壳和石英斑晶中的熔体包裹体和流体-熔体包裹体为研究对象,使用高温热台和激光拉曼进行分析。结果显示熔体包裹体的熔融温度在750~1027℃之间(平均为916℃),熔体-流体包裹体的均一温度在475~650℃之间(平均为562℃),而包裹体内的硅酸盐矿物和稀土矿物的存在表明巴尔哲岩体的岩浆-热液演化及其对稀有稀土矿化的制约。 |
| 关 键 词： | 稀有稀土矿床 熔体包裹体 流体-熔体包裹体 岩浆-热液过渡 巴尔哲 |

| Abstract: | Melt inclusion is consisting by the composition of original magma,which was sealed in minerals.It is the primary sample for the study of magmatic evolution and mineralization,for its preserving the physical and chemical information effectively during the formation of the hosted minerals in the primary magma.The melt inclusions from quartz phenocrysts and the melt-fluid inclusions from the pegmatitic shell was carried on the Linkam TS1500 and Renishaw RM-2000 laser Raman spectrometer,in this study.The result... |
