摘　　要：首次在新疆苏吉泉花岗岩中发现一种细长针状矿物,经高分辨电镜能谱分析其化学成分为SiO2。选区电子衍射数据分析表明其结构为α-石英。准纳米针状石英长度可达10500nm,宽度为137nm。最后,讨论了研究准纳米针状石英及针状石墨的意义。The authors discovered a kind of long and thin needle form mineral among a graphiting granite in Sujiquan, Xinjiang at the first time, and its chemical composition SiO2 by high resolution transmission electronic microscopy energy spectrum analysis. Selected area electronic diffraction data analysis showed its structure is α-quartz. The length of quasi-nanometer needle form quartz can reach 10500nm, and the width 137nm. Finally, authors discussed the meaning of studying allowing nanometer needle form quartz and needle form graphite.
