摘要:
大兴安岭北段雅鲁河断裂为典型的活动断层，对区域晚更新世地质和地貌演化及现代地震具有控制意义。在扎兰屯市成吉思汗镇北雅鲁河东侧发现雅鲁河断裂活动记录，以野外资料为基础，通过相关松散堆积物的光释光测年，厘定断层活动特征和活动时限，并结合相关经验公式，估测该记录反映的古地震特征。研究结果显示，雅鲁河断裂晚更新世在扎兰屯南部地区存在断层活动，断层走向近SN向、倾向265°、倾角约55°，性质为逆断层；断层活动错断了中生代流纹岩和晚更新世早-中期洪冲积物，并被晚更新世晚期残积和冲积物覆盖，断层活动发生在距今53.4±6.7~39.1±3.6ka之间；活动记录所反映的古地震矩震级（M0）和面波震级（Ms）为6.7级，地震发生时地表破裂长度（SRL）约为30.2~37.8km。
Abstract:The Yahuhe fault in northern Da Hinggan Mountains is a typical active fault, and it is of significance in the study of the Late Pleistocene regional geological and geomorphologic evolution and modern earthquake. The authors discovered the active records of Yaluhe fault on the east of Yalu River in northern Genghis Khan Town of Zhalantun City. In this paper, on the basis of detailed field data, the authors determined the fault activity characteristics and time limit through the OSL dating of loose deposits, and estimated the ancient seismic features of the fault active records combined with relevant experience formula. The study results show that the movement of Yaluhe fault in the south of Zhalantun occurred in the Late Pleisotocene. The fault is nearly SN-striking, with dip 55° and dip angle 265°, being a thrust fault. The fault dislocated Mesozoic rhyolite and early to middle Late Pleistocene pluvial-alluvial deposits, and was covered by the Late Pleistocene eluvial and alluvial deposits. The fault happened at 53.4±6.7~39.1±3.6ka. As active record reflected, the ancient seismic moment magnitude (M0) and surface wave magnitude (Ms) was about 6.7, and surface rupture length (SRL) was about 30.2~37.8km at the time of the earthquake.
