摘　　要：皮亚曼背斜两翼下二叠统原生剩磁的同褶皱检验结果表明原生剩磁主要是同沉积剩磁，其结果显示，皮亚曼背斜开始发育的时间不晚于早二叠世。从东邻杜瓦地区采集的下二叠统古地磁样品，对测试统计结果经同褶皱检验后得出同样的结论。The synfold examination of Lower Permian remanent magnetization from the two limbs of Piyaman anticline shows that the primary remanent magnetization is mainly the synsedimentary remanent magnetization,the result indicates that the development of Piyaman anticline began not later than Early Permian.After synfold examination,the measurement and statistics of the samples collected from Lower Pemian of east neighboring Duwa regiion reachs a same conclusion.

关 键 词：皮亚曼背斜 剩磁 同褶皱检验
