韧性剪切带与不协调褶皱The Ductile Shear Zone and Disharmonic Fold

露头级韧性剪切带挟持于块状砂质灰岩(左侧)与薄板状灰岩(右侧)之间。剪切带中,地层变形强烈,原生层理揉皱形成平卧和倒转褶皱,并成变形带中的集合块状旋转体。岩层和方解石脉被拉断,成为石香肠或布丁构造韧性剪切带两侧地层变形较微弱,呈舒缓褶曲。总体构成不协调褶皱景观。

Ductile shear zone sandwiched between massive sandy limestone (on left) and laminated limestone (on right). In shear zone the stratum produced strong deformation; native bedding formed the recumbent fold or overturned fold, and became the massive rotator in deformation zone. Rock formation and calcite vein were pulled to become boudinage. The stratum deformation was relatively weak to assume stretched fold on both sides of ductile shear zone. Overall it is a discordant foldlandscape composition.
