| 摘 要： | 详细的野外观察和室内研究表明,桃林断裂变质带中存在有糜棱岩和碎裂岩两个系列的断裂变质岩,并具分带性,说明该带经历了韧性和脆性两个不同机制的变形阶段。笔者认为该断裂变质带早期为一韧性剪切带,晚期叠加了脆性断层。

| Abstract: | The field observation and indoor investigation indicate that there are two series of fault-ed metamorphic rocks in Taolin faulted metamorphic zone, mylonite series and cataclasite se-ries. They appear as zoning, which shows that this zone has experienced two different mech-anism deformations, brittle and ductile. Authors put forward a new viewpoint that theTaolin faulted metamorphic zone is a ductile shear zone in early stage and brittle faults add toit in later stage. |
