一、国 际 专 题

（1）Progress in studies of geophysics and regional dynamics of Asia
Conveners: Sidao Ni, Ling Chen and Huajian Yao
Asia features various tectonic units from very stable cratons to active inter-plate and intra-plate deformation. High seismicity and assorted tectonic units make Asia a focus of geophysical and geodynamical studies. This session invites abstracts on new findings, innovative theories and methods in geophysics, geodesy and geodynamics, which will help depict present state and image crustal/mantle structure and unravel dynamic process of Asia. Studies on understanding and mitigating geohazards (including earthquakes, volcanoes, landslides, etc) in Asia are welcome as well.

（2）Microseismic monitoring and inversion
Conveners: Xu Chang, Haijiang Zhang and Yibo Wang
Microseismic is defined as the emission of elastic energy when the rocks are fractured. It could be caused by natural phenomena or human activities, such as volcanic eruptions, mining, groundwater exploitation, and the fracturing of unconventional reservoirs. The microseismic events could be used to monitor the changes in the physical properties of the subsurface and offer valuable information of the underground medium for different industries. This session will focus on microseismic theory, methods and applications. The research areas of the accepted abstracts include microseismic focal mechanisms, the characteristics of microseismic responses, microseismic modeling and inversion, microseismic signal processing, microseismic monitoring and application case studies, the research and development of microseismic monitoring equipment, and cross-disciplinary problems associated with microseismicity. The submitted abstracts and oral presentations should be done in English.

（3）Exploration and development, technology and research on shale gas
Conveners: Shujing Bao,Xiao Li,Jinchuan Zhang, Hongyan Wang, Zongquan Hu, Shoumai Ren
Shale gas is an important resource which will take place of conventional oil and gas resources. With the successful developing of shale gas in North America, the U.S. energy policy and the World resource pattern have been changed. China has potential shale gas resource, wide distribution of gas shales and is rich in multi-strata system. However, it needs to strengthen on the research of shale geological evaluation, core area selection, testing technology and scientific study. In the past two years, we have made significant progresses in the following areas. ① study on the shale formation geological background and depositional environment. ② selection on the core area of shale gas and key parameters. ③shale gas occurrence mechanism and enrichment patterns. ④shale horizontal well drilling and hydraulic fracturing. In this topic, we will invite some famous experts to discuss and exchange on these issues.

（4）The composition，structure and origin of oceanic lithosphere and deep mantle processes
Conveners: Lihui Chen, Guoliang Zhang, Zhen Sun, Yaoling Niu
Formation, evolution, subduction of oceanic lithosphere, the trench-arc-basin system, seamounts and islands developed in ocean basins, are the main objects to explore the internal dynamics of the Earth, and to improve the theory of plate tectonics. The mechanical processes in subduction zone determine the distribution of land and sea, while the metamorphism in subduction zone not only causes related magmatism and mineralization processes, but also largely controls the material cycling of Earth’s interior. These geological processes also fundamentally affect the basic processes of surface and near-surface oceanic sedimentary environment. As a result, it needs scientists to make a multidisciplinary and comprehensive study of petrology, geochemistry, geophysics, structural geology, sedimentology, paleontology and so on. In addition, discovery of ancient seamount fragments from orogenic ophiolites in recent years provides a new perspective in reconstructing the formation and subduction processes of ancient ocean basins, as well as the genesis of ancient seamounts. This session is dedicated to the interdisciplinary study of sub-oceanic deep structures and mantle processes, and welcomes recent progresses associated with modern and ancient oceanic plate tectonics and mantle processes, including sedimentology, paleontology, petrology, geochronology, geophysics, and geochemistry.
