摘要: 红山子晚侏罗世早期火山盆地位于西拉木伦河—长春缝合带以南、康宝—围场—赤峰—开原断裂带以北的辽源地块,其中赋存铀钼矿床的流纹岩为肉红色流纹岩和灰白色流纹岩。为了查明流纹岩的物质来源和形成的构造背景,本文分析了流纹岩的主量元素、微量元素、稀土元素和Sr-Nd-Pb同位素组成。分析结果显示:流纹岩具有高SiO2、K2O和Fe2O3/FeO值,低Al2O3、CaO和MgO的特征,肉红色流纹岩比灰白色流纹岩的SiO2含量略低、(K2O+Na2O)含量高和Fe2O3/FeO值略高;肉红色流纹岩和灰白色流纹岩均有较高的稀土含量,明显富集轻稀土,显著亏损铕;高场强元素Nb、Ta、Zr、Hf、Ce、Y、Ga和大离子亲石元素Rb、Th、U的含量较高,但大离子亲石元素Ba、Sr的含量低且变化较大,具有A1型流纹岩、低Sr-Ba流纹岩和板内拉张构造流纹岩的微量元素特征;具有较小的(87Sr/86Sr)i、较高的εNd(t)、较年轻的TDM2和较低的(206Pb/204Pb)i、(207Pb/204Pb)i、(208Pb/204Pb)i,指示流纹岩是源于EMⅠ富集地幔的中元古代年轻下地壳部分熔融的产物,并在岩浆过程中经历了结晶分异。肉红色流纹岩和灰白色流纹岩的差异可能与年轻下地壳物质的成分差异有关。
