    The discovery of aegirine in metamorphosed granite of southeastern Dabie MTS and Its Geological Implications

  4. 它以其下列特征与本区未变质花岗岩和围绕它的低压花岗质片麻岩相区别:(1)有标型矿物多硅白云母和长石的石榴石反应边;

    It can be distinguished from the unmetamorphosed Mesozoic granite and the low pressure gneiss by the features : ( 1 ) the key metamorphic minerals : phengite and coronal garnet around albite ;

  5. 石英硬玉岩原岩包括正变质的花岗岩和奥长花岗岩、副变质的酸性火山碎屑岩和长石石英砂岩。

    The protoliths of quartz jadeitite include metamorphosed granite , trondhjemite , acidic volcanic rocks and feldspar-quartz sandstone .

  6. 北喜马拉雅变质-花岗岩带与高喜马拉雅结晶岩相比,从变质作用到岩浆活动均有很大的相似性。

    Compared the metamorphism and magmatic activity with the high Himalayan crystalline rocks , the north Himalayan metamorphic-granite belt bears strong similarities with the high Himalayan belt .

  7. 局部破碎变质带内花岗岩类中Cu、Pb、Zn成矿元素含量的相关性说明多金属成矿元素来自同一围岩,总体显示成矿不但严格受构造控制,而且成矿后期改造对它的叠加作用也十分显著。

    The relevance among Cu , Pb and Zn in the granites in local fractured metamorphic belts shows that polymetallic ore-forming elements come from the same wall rock . Mineralization is not only severely controlled by structures but also obviously affected by later superimposition and reformation .
