摘要: 构造运动、岩浆活动、变质作用、矿床形成等地质事件节律的耦合，表明吉黑复合造山带古亚洲洋构造体制结束的综合标志时间为250~230 Ma，太平洋构造体制启动的综合标志时间为227~222 Ma.从全球构造观之，它们受Pangaea联合古陆形成的时间（330~230 Ma）和进入新超大陆旋回（230~0 Ma）首次裂解的时间（224 Ma）所制约.

Abstract: The rhythmic coupling of geological events of tectonic movement, magmatism, metamorphism, deposit formation and so on indicate that, for the Ji-Hei composite orogenic belt, the ending time of the Paleo-Asian Ocean tectonic domain is 250-230 Ma; while the starting time of the Pacific Ocean tectonic domain is 227-222 Ma. From the view of global tectonics, they are constrained by the forming time of Pangaea (330-230 Ma) and its first splitting time (224 Ma) after it entered the new super-continent cycle(230-0 Ma).
