| 摘 要： | 对河北蔚县九宫口断层重叠带进行了地质和地貌观察、年龄测定和断层落差分析。结果表明，伴随重叠带内的断层生长，位移发生转移，而且，原来两个独立的断层段演化成为互相关联的单一断层。岩浆活动和掀斜作用是该重叠带演化的原因

| Abstract: | When normal faults overlap each other in extentional direction the overlapping faults and the overlapping area will compose a fault overlap zone. Fault overlap zones with a separation more than several kilometers are usually considered as segment boundaries in studying earthquake rupture segmtntation. The Jiugongkou fault overlap zone in Weixian, Hebei, however, presents a typical opposite example which can not be regarded as a segment boundary. The Jiugongkou fault overlap zone is located on the southern |
