Abstract About 800 new and 1200 already published laser ablation inductively coupled plasma mass spectrometry analyses of quartz from rare-metal granites and related greisens, quartz-tourmaline rocks and quartz veins were evaluated in order to define typical trace-element signatures of quartz of different origin. The studied dataset comprises typical examples of sub-aluminous to slightly peraluminous plutons (A-type granites of the Kimi stock, Finland; Eastern Erzgebirge, Czech Republic; Orlovka, Russia and Ongon Chairchan, Mongolia), and strongly peraluminous plutons (S-type granites of Beauvoir, France; Cornwall, England; Panasqueira and Argemela, Portugal; Western Erzgebirge, Czech Republic). Additional 700, mostly already published, analyses of quartz from barren granites of all geochemical types (I, S, A-type), rhyolites and barren and rare-element pegmatites were evaluated for comparison. Compiled data reveal high diversity in the contents of trace elements in quartz even among rocks of similar geochemical composition. The most common trace elements in magmatic quartz are Al, Li and Ti with medians of 447, 39.6 and 17.4 ppm in S-type rare-metal granites, and 160, 15 and 6.6 ppm in A-type rare-metal granites. The contents of all these elements in greisens and quartz veins are significantly lower than in their parental granites. Al contents above 450 ppm should serve as a reliable indicator of S-affinity of the analyzed granite, while contents

S型和A型稀有金属花岗岩石英的化学特征——总结

摘要 为了确定不同产地石英的典型微量元素特征，评估了大约 800 个新的和 1200 个已发表的稀有金属花岗岩和相关石英、石英-电气石岩和石英脉石英的激光烧蚀电感耦合等离子体质谱分析。 . 研究的数据集包括亚铝质至微铝质岩体（芬兰基米岩的 A 型花岗岩；捷克共和国东部厄尔士山脉；俄罗斯奥尔洛夫卡和蒙古 Ongon Chairchan）和强过铝质岩体（S 型波伏瓦的花岗岩，法国；康沃尔，英国；Panasqueira 和 Argelela，葡萄牙；西厄尔士山脉，捷克）。另外 700 篇（大部分已经发表）对所有地球化学类型（I、S、A 型）的贫瘠花岗岩的石英进行了分析，对流纹岩和贫瘠和稀有元素伟晶岩进行了评估以进行比较。汇编数据显示，即使在地球化学成分相似的岩石中，石英中微量元素的含量也具有高度多样性。岩浆石英中最常见的微量元素是 Al、Li 和 Ti，S 型稀有金属花岗岩的中值分别为 447、39.6 和 17.4 ppm，A 型稀有金属花岗岩的中值分别为 160、15 和 6.6 ppm。灰岩和石英脉中所有这些元素的含量均显着低于其母体花岗岩。超过 450 ppm 的铝含量应作为分析花岗岩 S 亲和性的可靠指标，而含量 岩浆石英中最常见的微量元素是 Al、Li 和 Ti，S 型稀有金属花岗岩的中值分别为 447、39.6 和 17.4 ppm，A 型稀有金属花岗岩的中值分别为 160、15 和 6.6 ppm。灰岩和石英脉中所有这些元素的含量均显着低于其母体花岗岩。超过 450 ppm 的铝含量应作为分析花岗岩 S 亲和性的可靠指标，而含量 岩浆石英中最常见的微量元素是 Al、Li 和 Ti，S 型稀有金属花岗岩的中值分别为 447、39.6 和 17.4 ppm，A 型稀有金属花岗岩的中值分别为 160、15 和 6.6 ppm。灰岩和石英脉中所有这些元素的含量均显着低于其母体花岗岩。超过 450 ppm 的铝含量应作为分析花岗岩 S 亲和性的可靠指标，而含量
