中文摘要：

板块构造研究成果与同位素精确定年数据的积累，使我们对发生在中国东部的晚侏罗世一早白垩世东亚多向汇聚作用有了深刻的认识。全球三大洋在晚侏罗世（165±5）Ma近乎同时的开启，以及东亚周边古太平洋、新特提斯洋和蒙古-鄂霍茨克洋的俯冲消亡，在中国中东部和东亚地区形成了多向挤压汇聚的燕山期构造体系，即东亚多向汇聚构造体系（简称东亚汇聚）。东亚汇聚启动了经典的燕山运动，发育了独特的构造变形特征。东亚汇聚构造体系具有两个近乎稳定的刚性陆核，即鄂尔多斯地块和四川（盆地）地块，在它们的周缘形成了晚侏罗世-早自垩世陆内多向挤压变形和似前陆盆地，如大巴山晚侏罗世前陆。此外，东亚多向汇聚构造体系影响了东亚和中亚大部分地区的板内变形作用，在中国大陆及其周边形成了反映南北向挤压的蒙古弧共轭走滑断裂系统、燕山-阴山陆内造山带、大别山-大巴山侏罗纪陆内造山带等典型的燕山期构造带。东亚汇聚具有深刻的全球构造背景与动力来源，是重要的科学研究问题。

英文摘要：

The accumulation of new data of plate tectonics and high-resolution isotopic dating brings on the profound under- standing of the tectonic events in eastern China during the Late Jurassic to Early Cretaceous. The simultaneous opening of three major global oceans during Late Jurassic （ since 165±5 Ma） and subduction of paleo-Pacific, Neo-Tethys and Mongo- lia-Okhotsk oceans around East Asia, forms Yanshanian multi-direction compressional and convergent tectonic system in eastern China and East Asia, which is named as East Asian multi-direction convergent tectonic system （ i. e., East Asia Convergence）. The East Asia Convergence initiates the classical Yanshan Movement, resulting in characteristic deformation styles in East China. The stable Ordos and Sichuan blocks compose the two rigid continental cores in the system, with Late Jurassic to Early Cretaceous multi-direction compressional deformation and foreland basins formed around them. Additionally, the East Asia Convergence affects the intra-plate deformation in east and central Asia during Yanshan movement, forms conjugated N-S compressional Mongolian Arc of strike-slip and thrust fault system, and intracontinental Yanshan-Yinshan and Dabieshan-Dabashan orogenes. The East Asia Convergence, with profound global tectonic settings and dynamic origin, is an important scientific topic.
