| 1 | 中亚增生造山过程与成矿作用研究进展显示文摘中亚造山带作为全球最大的显生宙增生型造山带,是大陆动力学和成矿作用研究的天然实验室.文章简要概述中国新中国成立以来中亚造山带研究发展情况,并对未来研究提出展望. 20世纪50~70年代是中亚造山带研究的奠基时期,各地质研究学派理论相继运用于解释中亚地区的地质演化.改革开放初期,李春昱先生等开创性地运用板块构造理论解析北疆及兴蒙地区大地构造演化,提出了西伯利亚、哈萨克斯坦、中朝-塔里木三大板块俯冲-碰撞的认识,并提出了索伦山至延边缝合线的观点. 20世纪90年代,中亚造山带研究进入快速发展期,前苏联学者提出了多陆块碰撞模型;土耳其学者提出了单一岛弧增生模型,指出中亚造山带是一种特殊类型的碰撞造山带.中国学者对中国北方地区的蛇绿岩、高压变质岩等进行了大量开拓性研究,划分了主要缝合带. 1999年,'中亚成矿域'概念被提出,并与环太平洋成矿域和特提斯成矿域并称全球三大成矿域.进入21世纪,鉴于中亚在大陆增生理论和成矿机制研究领域的重要性,中亚造山带研究成为国际学术前沿.中国在中亚地区布局了一系列科研项目,催生了一大批重要科研成果,包括微陆块属性、蛇绿岩时代和构造背景、岩浆弧性质、增生楔识别和解剖、区域变质-变形作用、俯冲带(超)高压变质作用、洋中脊俯冲、地幔柱与板块相互作用、多岛海构造古地理与复式增生造山时空格架、大陆增生、增生成矿、构造叠加改造等.这些成果产生了重要的国际影响.展望未来,中亚造山带主要有以下几方面的内容需要进一步深入研究:(1)古亚洲洋早期演化历史及起始俯冲机制;(2)古亚洲洋外部造山带(Extroversion)的增生机制;(3)古亚洲洋地幔属性及其时空分布;(4)古亚洲洋与特提斯洋相互作用过程;(5)显生宙大陆增生机制及其全球对比;(6)中亚成矿域增生成矿机制;(7)大陆改造机制. | 肖文交 宋东方 Brian FWINDLEY 李继亮 韩春明 万博 张继恩 敖松坚 张志勇 | 2019 | 中国科学:地球科学2019，49，10： | 73 |
| 2 | Accretionary processes and metallogenesis of the Central Asian Orogenic Belt:Advances and perspectives显示文摘As one of the largest Phanerozoic orogens in the world,the Central Asian Orogenic Belt(CAOB)is a natural laboratory for studies of continental dynamics and metallogenesis.This paper summarizes the research progresses of the accretionary processes and metallogenesis of the CAOB since the Peopled Republic of China was founded,and puts forward the prospect for future research.During the early period(1950s-1970s),several geological theories were applied to explain the geological evolution of Central Asia.In the early period of China's reform and opening-up,the plate tectonics theory was applied to explain the evolution of the northern Xinjiang and Xingmeng regions,and the opinion of subduction-collision between Siberian Kazakhstan and China-North Korea-Tarim plates was proposed.The idea of the Solonker-Yanbian suture zone was established.In the 1990s,the study of the CAOB entered a period of rapid development.One school of scholars including geologists from the former Soviet Union proposed a multi-block collision model for the assemblage of the CAOB.In contrast,another school of scholars,led by a Turkish geologist,Celal Sengor,proposed that the Altaids was formed through the growth and strike-slip duplicates of a single island arc,and pointed out that the Altaids is a special type of collisional orogen.During this period,Chinese geologists carried out a lot of pioneering researches on ophiolites and high-pressure metamorphic rocks in northern China,and confirmed the main suture zones accordingly.In 1999,the concept of'Central Asian metallogenic domain'was proposed,and it became one of the three major metallogenic domains in the world.Since the 21st century,given the importance for understanding continental accretion and metallogenic mechanism,the CAOB has become the international academic forefront.China has laid out a series of scientific research projects in Central Asia.A large number of important scientific research achievements have been spawned,including the tectonic attribution of micro-continents,timing and tectonic settings of ophiolites,magmatic arcs,identification and anatomy of accretionary wedges,regional metamorphism-deformation,(ultra)high-pressure metamorphism,ridge subduction plume-plate interaction archipelagic paleogeography and spatio-temporal framework of multiple accretionary orogeny,continental growth accretionary metallogenesis,structural superposition and transformation etc.These achievements have made important international influences.There still exist the following aspects that need further study:(1)Early evolution history and subduction initiation of the Paleo-Asian Ocean;(2)The accretionary mechanism of the extroversion Paleo-Asian Ocean;(3)The properties of the mantle of the Paleo-Asian Ocean and their spatiotemporal distribution;(4)The interaction between the Paleo-Asian Ocean and the Tethys Ocean;(5)Phanerozoic continental growth mechanism and its global comparison;(6)Accretionary metallogenic mechanism of the Central Asian metallogenic domain;and(7)Continental transformation mechanism. | Wenjiao XIAO Dongfang SONG Brian FWINDLEY Jiliang LI Chunming HAN Bo WAN Ji'en ZHANG Songjian AO Zhiyong ZHANG | 2020 | Science China Earth Sciences2020，63，3： | 16 |
| 3 | Rollback,scissor-like closure of the Mongol-Okhotsk Ocean and formation of an orocline:magmatic migration based on a large archive of age data显示文摘Tracing the closure of oceans with irregular margins and the formation of an orocline are crucial for understanding plate reconstruction and continental assembly.The eastern Central Asian Orogenic Belt,where the Mongol-Okhotsk orocline is situated,is one of the world’s largest magmatic provinces.Using a large data set of U-Pb zircon ages,we updated the timing of many published igneous rocks,which allowed us to recognize tightly’folded’linear Carboniferous-Jurassic magmatic belts that wrap around the Mongol-Okhotsk suture and their migrations both sutureward and suture-parallel.The new successive magmatic belts reveal a rollback,scissor-like(or zipper-like)closure of the Mongol-Okhotsk Ocean that was fundamentally controlled by coeval subduction rollback and rotation of the Siberian and Mongolian-Erguna blocks.This study also demonstrates the complex mechanisms and processes of the closure of an ocean with irregular margins and the formation of a consequent orocline. | Tao Wang Ying Tong Wenjiao Xiao Lei Guo Brian FWindley Tatiana Donskaya Shan Li Narantsetseg Tserendash Jianjun Zhang | 2022 | National Science Review2022，9，5： | 0 |
