| 摘 要： | 琉璃庙地区变质杂岩主要由变质上壳岩、变质深成侵入杂岩及其脉岩群组成.它们多数经韧性变形改造形成各种类型糜棱岩和构造片岩.研究表明,变质上壳岩原岩主要以钙碱性火山(熔)岩为主.本区变质杂岩经历了三期变质变形作用,即高角闪岩相区域变质作用形成大型复式同斜紧闭褶皱;绿帘角闪岩相动力变质作用及强烈的韧性变形,形成了以蓝闪石为特征的不同强度的糜棱岩带;绿片岩相动力变质作用和韧脆性变形作用.

| Abstract: | The metamorphic complex in Liulimiao area is mainly composed of metamorphic supercrusted rocks, metamorphic plutonic intrusive complexes and dyke sworms. Most of these rocks had been transformed into all kinds of mylonites and tectonice schists through ductile deformation. Study has shown that the primary rocks of metamorphic supercrustal rocks are mainly calc-alkaline volcanic rocks. The metamorphic complexes in this area underwent three period of metamorphism and deformation, high amphibolite facies metamorphism which formed giant multiple homoclinal tigh folds, dynamic metamorphism of epidote-amphibolite facies and strong ductile deformation, which formed intensityly different mylonite belts with the glaucophane occuring in its central part, dynamic metamorphism of green schist facies and ductile- brittle deformation. |
