摘要
云南建水县普雄铌稀土矿区的主要断层划分为北东向逆断层、北东东向左行平移断层和北西西向右行平移断层。其中北东向逆断层由北西、南东向的挤压作用形成,构造变形时期属燕山晚期。北东东向左行平移断层由北西、南东向的挤压作用派生的近南北向水平剪切作用形成,构造变形时期属燕山晚期。北西西向右行平移断层由近东西向的右行水平剪切作用形成,构造变形时期属喜马拉雅晚期。
The principal fault of Puxiong Nb REE Orefield in Jianshui,Yunnan can be divided into NE thrust,NEE left-handed strike-slip fault and NWW right-handed strike-slip fault. The NE thrust is formed by NW,SE compression,the deformation period belongs to Late Yanshanian. NEE left-handed strike-slip fault is formed by nearly NS horizontal shear derived from NW,SE compression,deformation period belongs to Late Yanshanian.NWW right-handed strike-slip fault is formed by nearly EW right-handed horizontal shear,deformation period belongs to Late Himalayan.
