1赣南大吉山五里亭岩体的锆石ELA-ICP-MS定年及其与钨成矿关系的新认识显示文摘大吉山是南岭地区一个著名的大型钨多金属矿床,五里亭岩体是矿区出露规模最大的火成岩体,岩性为中粗粒似斑状黑云母二长花岗岩。锆石 ELA-ICP-MS 定年结果表明其形成年龄为 237.5±4.8 Ma,属印支期岩浆活动的产物。与南岭地区典型钨多金属矿床成矿岩体相比,五里亭岩体贫硅,富钙、镁、铁,Rb/Sr、Rb/Ba 和 U/Th 比值低,K/Rb 比值高,铕负异常不显著,分异指数低,尚未达到矿化岩体的分异演化程度,不具备矿化岩体的地球化学特征。元素—同位素综合示踪显示区内白云母碱长花岗岩为五里亭岩体经高度分异演化的产物,它与钨多金属矿成矿直接有关。矿区范围内出露的闪长岩起源于地幔,这一岩浆侵位所引起的高热场环境有利于花岗质岩石的形成与演化,对成矿具有重要的意义。邱检生 McInnes BIA 徐夕生 Allen C M 2004地质论评2004,50,2:78
2广东龙窝花岗闪长质岩体的年代学、地球化学及岩石成因显示文摘龙窝岩体是南岭地区燕山早期具幔源组分贡献的花岗岩的典型代表,其主体岩性为花岗闪长岩,岩体中含有深色闪长质包体,锆石ELA-ICP-MS定年结果表明花岗闪长岩的形成年龄为169.1±2.5Ma,属中侏罗世岩浆活动的产物。地球化学特征上,该岩体铝弱过饱和(A/NKC=1.0~1.1),相对贫碱,富钾(K_2O/Na_2O=1.15~1.45),富轻稀土和大离子亲石元素(如Rb、Cs、Th、U),贫高场强元素(如Nb、Ti)。闪长质包体具有与寄主岩相似的矿物组合,但铁镁矿物含量及过渡族元素(V、CR、Co、Ni)丰度相对偏高,二者的主量和微量元素表现出混合成因的演化趋势。寄主岩与包体具有相近的Sr、Nd同位素组成,I_(Sr)和ε_(Nd)(t)值分别为0.70843~0.70995、-6.53~-8.89和0.70797~0.70882、-4.71~-9.24,均表现出壳幔混源花岗岩类岩石的特点。二元混合模拟计算显示寄主岩与包体成岩过程中地幔物质的混入比例分别为32.9%~40.4%和 31.8%~46.4%。通过对岩石产出构造背景及地质地球化学特征的综合分析,表明龙窝花岗闪长岩及其中的闪长质包体是在伸展-引张环境下,由幔源基性岩浆及其诱发的壳源长英质岩浆混合作用的产物。邱检生 胡建 McInnes B I A 蒋少涌 徐夕生 Allen C M 2004岩石学报2004,20,6:19
