英文摘要	兴蒙造山带东缘包括松辽盆地以东的小兴安岭－张广才岭造山带、布列亚－佳木斯－兴凯地块和锡霍特－阿林增生杂岩带，是古亚洲洋与古太平洋构造体系过渡的地带。岩浆岩研究表明，古太平洋板块在佳木斯地块的俯冲作用最早可能始于早二叠世，三叠纪－早侏罗世时，其俯冲影响到牡丹江断裂两侧，形成了南北向分布的岩浆岩带以及由黑龙江杂岩为代表的增生杂岩带，晚侏罗世－早白垩世时期，锡霍特－阿林的地体群沉积了来自佳木斯－兴凯地块和华北克拉通的碎屑物。由于古太平洋板块俯冲方向的变化，板片俯冲作用相关的岩浆活动在这段时期逐渐减弱，大量北北东向的左行走滑断裂将锡霍特－阿林的地体向北运移、拼贴至现今位置；同时，中国东北地区则转为伸展环境。晚白垩世时期，俯冲作用再次活跃，产生了锡霍特－阿林地区广泛的岩浆活动。; The eastern part of the Xing-Meng Orogenic Belt(XMOB)consists of the Lesser Xing’an-Zhangguangcai Range Orogenic belt,the Bureya-Jiamusi-Khanka Block and the Sikhote-Alin accretionary belt.This area is located between the Paleo-Asian oceanic and Paleo-Pacific tectonic regimes.Recent researches imply that the Paleo-Pacific subduction might have begun since early Permian and influenced the both sides of the Mudanjiang Fault during Triassic,which generated a N-S trending magmatic belt and accretionary complexes,such as the Heilongjiang Complex.In Late Jurassic to Early Cre-taceous,some tectonostratigraphic terranes were produced in Sikhote-Alin,which were then dismembered and migrated northwards in late Early Cretaceous by sinistral strike-slip faults.The continental margin parallel transportion weakened subduction-related magmatism in NE China which was under an extensional setting.However,in Late Cretaceous,the Pa-leo-Pacific subduction was re-activated in the eastern XMOB,which contributed to the magmatism in Sikhote-Alin.; 国家重点基础研究发展计划; 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 6; 1098-1108; 35
