| 摘 要： | 东准噶尔苏吉泉石墨矿赋存于黄羊山复式花岗岩体的黑云母碱长花岗岩和角闪碱长花岗岩接触带,构成NW向延伸的长英质石墨混染带.矿体多呈不规则透镜状,平面上为短轴或近似等轴状,主矿体附近发育有巢状或小透镜状矿体.矿石多具球状构造,石墨球体间为石英和长石组成的致密长英质胶结物,球体除石墨外还有含量不等的粗粒自形长石、石英和云母等.利用X射线粉晶衍射技术、DTA分析及显微镜下观察,对该矿床特征进行研究并与国内其他石墨矿床进行地质学、矿物学研究对比,发现其晶胞参数和晶胞体积最小,放热峰起始温度最高及有序度最好.结合前人δ13C同位素分析结果,认为成矿物质为有机碳,矿床属岩浆成因. |
| 关 键 词： | 东准噶尔 苏吉泉 石墨 球状构造 花岗岩 |
