| 中文摘要: |
| 瑶岗仙复式岩体、千里山复式岩体、骑田岭岩体和九峰岩体都是亚碱性、过铝质、放射性元素含量高的花岗质岩石；而作为成矿小岩体的瑶岗仙复式岩体区别于区域大花岗岩体如九峰岩体、骑田岭岩体,其酸性和分异演化程度更高,与后者相比存在分异演化上的连续性和继承性。瑶岗仙复式岩体富含挥发分,第一期和第二期侵入岩在演化过程中发生了强烈的流体—熔体相互作用；第三期石英斑岩同样也具备良好的成矿条件,但随着地质条件的改变,其沿着构造薄弱地带快速上升,并以含W元素较高的石英斑岩就位,规模明显小于前两期,且标志着成矿作用的结束。 |
| 英文摘要: |
| The Yaogangxian complex massif, Qianlishan complex massif, Qitianling and Jiufeng massif are granitic rocks which are characterized by sub-alkaline, peraluminous and high concentration of radioactive elements. As ore-bearing massif, the Yaogangxian complex pluton is small size, more acidic and higher evolution level than other large-sized regional granite body like Qitianling and Jiufeng massif. Also, it has the evolution continuity and inheritance. The Yaogangxian complex massif is rich in volatile components, and the intense fluid-melt interaction occurs during the first and second stage of intrusion evolution.The third stage of quartz porphyry also has favorable metallogenic contidion, which is rich in ore-forming elements, moved up along the structural weak position quickly and emplaced in the form of quartz porphyry bearing high content of tungsten. The quartz porphyry stage is much smaller than the former stages of granite intrusions, and commonly indicated the end of the mineralization process. |
