Palinspastic reconstruction for tectonics of Northeast China and Its Vicinity

Journal of Earth Science 1998年第3期17卷 20-30页

Collision and amalgamation of continent and microcontinent block were recognized as one of the major processes for building up a continent. The pre Jurassic structure of Northeast China and its adjacent region (including south of Russia Far East, north of North Korea and inner part of southwest Japan) is characterized by collision and amalgamation of microcontinent blocks, such as the North China block (NCB), Northeast China block (NECB), Khanka block and Hida *** central Jilin belt and Yanbian Grodekovsk belt that juxtapose and amalgamate these blocks in between in Northeast China and its vicinity were formed by a series of rock assemblages that are typical for Paleozoic active continental margin island arcs. The dominant Permian marine sequences in Yanbian (Yanbian Grodekovsk) belt, which are known for bearing transitional marine fauna, include turbidite olistostrome sediments of a slope facies, and limestones, sandstones as well as siltstones of a neritic littoral facies sediments along with predominant acidic to intermediate volcanic materials. The Maizuru belt in southwest Japan is supposed to be the equivalent of Yanbian Grodekovsk belt. The central Jilin belt consists of a well developed sedimentary sequence and volcanics of Paleozoic. The Bamiantong Gudonghe Fuerhe Chongjin suture complex in Northeast China and the equivalent Sangun Akiyoshi belt in southwest Japan serve as a major suture zone among these microcontinental blocks and belts.

新特提斯洋的脱碳俯冲被认为在新生代气候变化中发挥了重要作用,但仍然缺少定量的研究.本研究使用改进的地震层析成像重建方法构建了过去的俯冲情景,并计算了印度-欧亚大陆碰撞区域的俯冲板块通量.新生代时期的俯冲板片通量和古气候参数的变化之间存在显著的同步性,表明这些过程之间存在因果关系.新生代早期,新特提洋内俯冲的关闭导致更多富含碳的沉积物沿着欧亚大陆边缘俯冲,为大陆弧火山的岩浆作用提供了更多的碳源,进一步引发了全球变暖.在全球气候达到早始新世峰值后,印度-欧亚大陆碰撞导致的新特提斯俯冲的突然终止造成了距今50~40 Ma期间大气中二氧化碳浓度的快速下降.距今40 Ma后,大气中的二氧化碳浓度逐渐降低,这可能是由于青藏高原的生长导致大陆风化作用增强所致.本文结果有助于更好地理解新特提斯洋演化的动态含义,并可能为未来的碳循环模型提供新的约束条件.

＜正＞ In this paper, we report the results of sedimentary studies on the Mesozoic sequences of Tibet since 1996, sponsored by the General Petroleum Corporation of China and the Natural Science Foundation of China. In the Early-Middle Triassic, an abyssal sea covered most of the Songpan-Ganzi area whereas a named Central Tibetan Landmass up to 400 km wide could have stretched across the Lhasa and Western Qiangtang blocks. In the Late Triassic, the Songpan-Ganzi sea closed at the latest stage, the Central Tibetan Landmass got reduced westwards away from southern Western Qiangtang, a littoral environment dominated Eastern Qiangtang, middle Western Qiangtang, and southeastern Lhasa, a shelf environment existed only in northern and southeastern
