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.

关 键 词:吉黑造山带  构造体制转换  时间标志  全球构造

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).
Keywords:Ji-Hei orogenic belt  transition of tectonic systems  time mark  global tectonics
