摘要:

中国中央造山系从西向东横亘在中国中部,从北向南、从西向东由祁连、阿尔金、柴北缘、西昆仑、东昆仑和秦岭(含桐柏—大别、苏鲁)6个造山带组成。大地构造位于特提斯构造域北部,经历了罗迪尼亚超大陆裂解以来的原特提斯和古特提斯多岛洋演化历程。本文系统梳理整合了中央造山系各时代约185个出露点的蛇绿混杂岩等洋壳残迹的物质组成、393个蛇绿岩等洋壳残块的测年数据,依据构造环境和时代分布,区划出7个OPS构造-地层区和15个分区。阐述了各区和分区的OPS的岩石组合与时空分布特征。在系统收集同位素测年和OPS年代序列划分对比的基础上,构建了中央造山系首个显生宙OPS地层格架和时空演化模式,并对中央造山系特提斯演化历程进行了讨论。

Abstract:

The Central Orogenic System spans the central part of China, comprising six NW-SE trending orogenic belts: the Qilian, Altun, North Qaidam, West Kunlun, East Kunlun, and Qinling. Tectonically located in the northern part of the Tethyan domain of China, it has undergone the evolution of the Proto- and Paleo-Tethyan archipelagic ocean systems since the breakup of the Rodinia supercontinent. This paper systematically compiles and integrates the geological records of ophiolitic mélanges and other oceanic crust remnants from over 185 outcrops of various ages in the Central Orogenic System (including 393 isotopic dating data). Based on tectonic settings and evolution with age constrained, seven OPS (Ocean Plate Stratigraphy) tectonic-stratigraphic provinces are delineated and further divided into 15 sub-provinces. The study introduces the lithological assemblages of OPS and their spatiotemporal distributions in each province and sub-province. Based on the division and correlation of OPS chronological sequences, the Phanerozoic OPS framework and its spatiotemporal evolution model of the Central Orogenic Belt is established for the first time and the evolution of Tethyan domain related to the Central Orogenic System is discussed.

Key words: Oceanic Plate Stratigraphy, spatial and temporal distribution, Phanerozoic, evolution of Tethyan Domain in China, the Central Orogenic System, tectonics
