Report placeConference hall of School of Silk Road

 

Brief introduction to the speaker:

    Timothy Kusky, graduated from the Earth and Planetary Science of John Hopki University, United States in 1990. He was introduced as a full-time professor and PhD adviser by the China University of Geosciences (Wuhan) in 2009. He was selected as The Thousand People Plan & Yangtze River scholar by Ministry of education of China in 2010. He is also the director of the Center for Global Tectonics of China University of Geosciences (Wuhan), GSA Fellow, American Geological Association. Now he is the associate editor of Journal of Earth Science, Geodinamica Acta, and the editorial board of the Lithosphere. The main research fields are: tectonic geology, regional tectonics, Precambrian crust evolution history, orogenic belt evolution, and Neotectonic activities and geological disasters. 

 

Brief introduction to the speech:

    Lateral escape and formation of new plate boundaries during continental collision is controlled by different driving forces including lateral extrusion, slab rollback, gravity collapse and basal drag. However, the relative contributions of these driving forces in old orogenic belts such as the eastern Tethysides of Asia are difficult to distinguish and evaluate quantitatively, because many resulting structures may be overprinted by younger events. The Anatolian plate, located within the active collision zone between the Arabian and Eurasian plates in the west-central Tethysides, represents the early stage of collision, where different driving forces have acted at different times and in different directions, forming different suites of structure, basins, and resources. For example, new plate boundaries formed as the North- and East Anatolian Fault Zones, and are presently forming in the diffuse zone between the westward and southward moving parts of Anatolia.

    This report will introduce the key scientific problems exist in Western Tethys that related to lateral escape, and geological and geophysical background in Anatolia, Turkey.

报告人简介:

Timothy Kusky (蒂姆·柯斯基)1990年博士毕业于美国约翰.霍普金斯大学地球与行星科学专业。20099月被中国地质大学(武汉)引进为全职特聘教授,博导。2010年入选教育部长江学者和中组部“千人计划”。中国地质大学(武汉)“全球大地构造中心”主任,美国地质协会会士(GSA Fellow)。现为Journal of Earth Science杂志副主编,Geodinamica Acta, Lithosphere杂志编委。研究领域主要为:构造地质学、区域大地构造、前寒武地壳演化史、造山带演化,以及新构造活动、地质灾害。

 

报告内容简介:

大陆碰撞带内刚性块体侧向移动是造山过程中最重要的阶段之一,也是威尔逊旋回中大洋盆地演化的最终阶段。不同时空尺度下多种驱动力(如侧向挤出、板片回撤、重力垮塌、板底拖曳)造成构造逃逸、下地壳部分熔融和流动,因此也控制着不同种浅表地质构造的发展、分布和矿产资源的富集。新特提斯洋闭合期间,西特提斯安纳托利亚板块处于阿拉伯—欧亚板块陆陆碰撞早期。相对东特提斯而言,西特提斯的陆陆碰撞过程正在进行中,形成的四个新构造域,受上述多种驱动力控制形成的浅部构造也各不相同,是识别和评估构造逃逸多种驱动力的最佳天然实验室。本报告将介绍西特提斯与板块构造逃逸相关的关键科学问题,以及土耳其安纳托利亚板块的宏观构造特征。

欢迎广大师生积极参与!
