摘　　要：在野外考察、室内分析的基础上对清平飞来峰的构造特征、形成机制进行了研究。其结果表明清平飞来峰具有明显的叠覆式特征,共分5层。各层峰体特征、成因各具特色,下部两层为推覆体,上部三层为滑覆体。推覆体与滑覆体共同构成同一飞来峰,为龙门山飞来峰中所少见。从而证实了龙门山飞来峰先发育推覆体,后发育滑覆体的地质景观确实存在。The structural deformation and genetic mechanism of the Qingping klippe in central Longmen Mountains are examined based on the field observation and indoor analysis. The Qingping klippe as an overlapping klippe may fall into five layers, each of which is variable in genesis and character. The lower two layers consist of thrust nappes, and the upper three layers are made up of gliding nappes. This phenomenon that both the thrust nappes and gliding nappes appear in the same klippe has not been found yet in other klippes of the Longmen Mountains, and illutrates the view that the development of the thrust nappes are earlier than that of the gliding nappes in the Longmen Mountains.
