摘要:

印支运动和燕山运动是中国东部中生代时期两次十分重要的造山运动。由这两次造山运动形成的构造带,既不是陈国达所说的地壳演化第三阶段的产物,也不是一些学者所谓的由板块内部动力产生的陆内(或板内)造山带。它们是在古太平洋动力体系作用下,在中国东部先成大陆地壳之上形成的上叠造山系,过去我们曾称其为中国东部滨太平洋大陆边缘活动(活化)带。中生代时期,在古太平洋动力体系作用下,于俄罗斯东北部—锡霍特阿林—日本—琉球—中国台湾—巴拉望一带形成亚洲东缘造山系,在邻接亚洲东部陆缘的中国东部大陆地壳之上形成中国东部上叠造山系。二者在同一动力体系作用下,同步发展,共同组成亚洲东部太平洋构造域规模宏大的巨型中生代造山系,彻底改变了亚洲东部印支造山前的构造面貌。

Abstract:

The Indosinian and Yanshanian orogenic movements are both important Mesozoic orogenies in eastern China. The resulted tectonic belts are neither products of the third stage of crustal evolution, as proposed by Chen Guoda, nor intracontinental (or intraplate) orogenic belts generated by intraplate dynamics, as argued by some scholars—rather, they are superposed orogenic belts created on the preformed continental crust in eastern China due to Mosozoic Paleo-Pacific dynamic system. In the past, these orogenic belts were called the peri-Pacific continent-marginal reactivated belts of eastern China. In the Mesozoic, under the effect of Paleo-Pacific dynamic system, the East Asia margin orogenic system formed along Northeast Russia-Sikhote Alin (Russia)-Japan-Ryukyu-Taiwan (China)-Palawan (Philippines) regions, while simultaneously the Mesozoic superposed orogenic system formed in the pre-existing continental crust in eastern China adjacent to the East Asia continental margin. The two orogenic systems, both driven by Mesozoic Paleo-Pacific dynamic system, developed synchronously to form the giant Mesozoic orogenic system in the Pacific tectonic domain in eastern Asia, radically changing the pre-Indosian tectonic framework of eastern Asia.

Key words: superposed orogenic belt, Indosinian orogenic cycle, Yanshanian orogenic cycle, Mesozoic superposed orogenic system of eastern China, Pacific tectonic domain
