| 摘 要： | 冀东三家地区太古宙灰色片麻岩,既不是简单的变质火山-沉积岩,也不是简单的混合片麻岩,其主体乃为早期伴有灰白色钢质混合岩化的英云闪长岩-奥长花岗岩-花岗闪长岩系列古侵入体,经过大规模强烈的深层次角闪岩相韧性剪切流变而改造成的深层次构造片麻岩。

| Abstract: | Evidences indicate that Archean gray gneisses within the Sanjia regionare neither the simple metavolcanic and meta-sedimentary rocks, nor thesimple migmatite or compound gneisses, but the deep-seated tectonic gneissesdeveloped from TTG serial plutons accompanied by earlier greyish-whitesodium migmatization through large-scale strongly ductile shearing withamphibolite facies in deep levels. The gray gneisses were superimposed bythe late narrow ductile shear zones with greenschist facies in a same direction. |
