| 摘 要： | 黄栗树地区位于张八岭超高压变质带东侧 ,该区变形构造可以划分为基底韧性变形带、韧脆性构造片岩带和流变褶皱带。流变褶皱构造发育于黄 (栗树 )—破 (凉亭 )断裂以东的震旦系和下古生界盖层岩系中 ,自北西向南东依次表现为翻转褶皱、平卧褶皱和倒转褶皱 ;流变褶皱与基底韧性—韧脆性变形呈渐变关系 ,并且与基底韧性—韧脆性变形具有一致的变形运动学和动力学特征 ,反映了扬子地块与华北地块碰撞造山期及折返过程的构造变形特点。

| Abstract: | The
Huanglishu area is located on the east side of the Zhangbaling ultrahigh-pressure
metamorphic zone. The deformation structures may be classified into the basement ductile
deformation zone, ductile-brittle structural schist zone and rheomorphic fold zone. The
rheomorphic fold structure is developed in the Sinian and Lower Paleozoic cover rock
series east of the Huanglishu-Poliangling fault. From northwest to southeast it is
manifested successively by facing down folds, recumbent folds and overturned folds. The
rheomorphic folds show gradational relationships with basement ductile and ductile-brittle
deformation and have the same deformation kinematic and dynamic features as the latter,
which reflects the structural deformation features during the collisional orogeny and
exhumation of the Yangtze and North China blocks. |
