摘要 花岗质岩石的片麻理受结晶作用和构造环境田双重控制,岩浆体系的结晶作用与变形作用的时间关系及变形的P-T条件是岩石组构形成的决定因素。 Gneissosity of granitic rocks is controlled by both crystallization and tectonic environments. The crystallization of intrusive magmatic systems, the time relations of deformation and the P—T conditions for deformation are the decisive factors for forming the fabrics and gneissosities of rocks.There is a distinction in fabric, body features and regional relations between granitic rocks in differeat crystallizing stages of magma under different environments and those deformated under different P—T conditions. Only through synthetical study in more aspects can the genesis of gneissosity be determined correctly.
