| 摘 要： | 寒岭—偏岭平移断裂带位于辽宁东部 ,是中国东部郯庐断裂东盘的一个次级断裂。它控制着辽东鞍山—本溪地区地质体的分布。通过对平移断裂的展布、形态、伴随构造、牵引构造、位移方向和幅度、平移时间、断层尾端及动力学演化等特征研究 ,认为该断裂主要活动于晚三叠世 ,在晚侏罗世—早白垩世最为活跃 ,伴随岩浆侵入活动、火山喷发及陆相沉积。断裂带长约 1 3 0km ,中段位移最大可达 3 1km ,向东西两端逐渐减少。该断裂活跃时期主要表现为左行平移性质。构造的活动 ,主要与中生代时期欧亚大陆与伊佐奈岐板块、太平洋板块的相互作用有关

| Abstract: | The Hanling-Pianling strike-slip fault zone is an important fault zone of the east of Liaoning, and a secondary fault at the east wall of the Tan-Lu fault zone in China. The fault zone controls the geological body distribution in the Anshan-Benxi region. Through the study of the extension, transcurrent features, subordinate structure and drag structure, direction, breadth and time of displacement, fault tail and dynamical evolution of the strike-slip fault, the authors suggest that the fault activity occurred from the Late Triassic to the Early Cretaceous and was most active at the Late Jurassic-Early Cretaceous, with intense magmatism, volcanism, and sedimentation of continental facies. The strike-slip fault is about 130 km long; the largest displacement reaches 31km in the middle; and at the two ends, the displacements are getting less. The fault shows a left-lateral displacement at the active time. The structure formation is a result of the interaction among the Eurasian plate, the Izanagi plate and Pacific plate. |
