| 摘 要： | 汉南超单元组合是扬子陆块晋宁期同构造侵位的巨大岩基，其内部结构、构造、分布、形态极有规律，与区域构造一致。晋宁期区域近EW向走滑斜冲机制派生的NE向延伸的拉张环境为岩浆侵位提供了潜在的空间，深成岩体的就位机制是构造位置、构造运动量、岩浆脉动量等诸多因素的综合反映。

| Abstract: | The Han Nan's ultra-unit assemblage is the enormous batholith formed by syntectonicemplacement of Yangtze landmass during the Jinningian movement, in which its inner textures, structures and shapes correspond with regional structure. The extensional setting inthe north-east direction, induced by nearly E--W substrike--slip movement during Jinningianepoch, provides the potential space for magma emplacement. It is thought that the plutoniteemplacement might be controlled by the structural position, tectonic momentum, magmamomentum. |
