| 摘 要： | 长乐-南澳构造带中发育有晚侏罗世早期、晚侏罗世晚期及早白垩世等3个不同时期的变质变形侵入岩。不同期次侵入岩具有不同的变质变形特征。根据糜棱岩的空间分布、糜棱叶理的切割关系等，表明构造带在中生代发生了3期韧性剪切变形及相关的动力变质作用。第一期为（北西西－南东东向）右行－推覆韧性剪切，具低角闪岩相变质、深部构造层次长石相...

| Abstract: | Metamorphic and deformed granitic rocks in Changle-Nan'ao fault zone was dividied into the early Late Jurassic,late Late Jurassic and Early Cretaceous three periods.Different period's granitic rocks had different characteristics of deformation and metamorphism.According to metamorphism and deformation style,and the foliation crosscutting relation in different period's intrusions,ductile deformation and related dynamic metamorphism in this tectonic zone can be divided into three stages: The first stage's duc... |
