Sessions Overview

Plenary Session: Progress and major achievements of deep earth exploration programs

Co-Conveners: Shuwen Dong(SinoProbe, China)Bob Detrick (IRIS, USA), Hans Thybo (ILP, Eurasia Institute of Earth Sciences, Istanbul Technical University, Turkey)Rixiang Zhu (Institute of Geology and Geophysics, CAS, Beijing)Qiuming Cheng (IUGS, China University of Geosciences, Beijing)

We invite review of major deep exploration programs, whether for academic or exploration objectives, or both together with new and upcoming programs such as SINOPROBE II. We hope for discussion of the role of international collaborative organisations, including ICDP, IRIS, ILP, IUGS and IUGG in furthering the above endeavors.

Session 1: Deep structure and dynamics of the Himalaya-Tibet orogen and global collision zones

Co-Conveners: Larry Brown(Cornell University, Ithaca, USA) , Rui Gao (SinoProbe, CAGS) , Simon Klemperer (Stanford University, USA) , Chengshan Wang (China University of Geosciences, Beijing)An Yin (State University of California at Los Angeles, USA) , Fenglin Niu (Rice University, USA)Xiaohui Yuan (GFZ German Research Center for Geosciences, Germany)

The Himalaya and Tibetan Plateau are the most spectacular manifestation of continent-continent collisional orogens that form the most prominent geologic features of Earth’s surface. This session will highlight recent SinoProbe and other studies of Tibet, but welcomes all studies of continental-continental collision zones around the world, including geologic, geochemical, geophysical and modelling studies that help us better understand lithospheric structure and dynamics.

Session 2: From continental rifting to formation of oceanic basins

Co-Conveners: Walter D. Mooney (United States Geological Survey, Menlo Park, USA) , Zhijun Jin (Sinopec Petroleum Exploration and Production Research Institute), Randy G.Keller(University of Oklahoma, USA), Jian Lin ( Woods Hole Oceanographic Institution, USA / South China Sea Insitute of Oceanology, CAS), Heidrun KOPP (GEOMAR, Helmholtz Centre for Ocean Research, Kiel, Germany), Sanzhong Li (Ocean University of China) 

Continental rifting is a fundamental process that can stall in extensional-basin formation, or ultimately can lead to the formation of oceanic basins.  This session welcomes all studies of continental rifting, extension, basin formation, and the formation of new oceanic basins.  Geologic, geochemical and geophysical studies are encouraged. High quality geophysical images of extended continental lithosphere and of oceanic basins are particularly welcome.

Session 3: Dynamics of intracontinental deformation

Co-Conveners: Zhenmin Jin (China University of Geoscxiences, Wuhan), Irina Artemieva (University of Copenhagen, Denmark), Ling Chen (Institute of Geology and Geophysics, CAS), Qin Wang (School of Earth Sciences and Engineering, Nanjing University, China)

This interdisciplinary session invites contributions from various disciplines in geophysics, geodynamics, and geochemistry that focus on structure and evolution of the continental lithosphere and on geodynamic processes within the continental interior. The session will present overview of the current knowledge on the structure of the crust and the upper mantle in different tectonic settings, ranging from Precambrian cratons, to sedimentary basins, continental rift zones, and intracontinental collisional orogens. Geodynamic studies will demonstrate the role of various processes in intracontinental deformation, ranging from collisional, extensional and strike-slip deformation by plate tectonics processes, to intracontinental deformation caused by lithosphere-mantle dynamic interaction associated with hotspots, large igneous provinces and large-scale impacts.

Session 4: Linking surface processes to deep earth dynamics

Co-Conveners: Sierd Cloetingh(Netherlands Research Centre for Integrated Solid Earth Sciences), Jeffrey Freymueller (University of Alaska, Fairbanks, USA), Michael Weber (GFZ German Research Center for Geosciences, Germany), Jing Liu (Institute of Geology, CEA), Yueping Yin (China Geological Survey, Beijing) 

One of the important developments in Earth science over the past decade has been recognition of the significance of linking deep Earth dynamic processes with surface and near-surface geologic processes. Observables from surface studies, such as basin stratigraphy, geomorphology of landscapes, changes in topography and surface loading, provide some of the principal constraints on geodynamic and tectonic models. Conversely, deep geodynamic processes give rise to the topography, erosion, and deposition. Surface manifestations of deep geodynamic processes have significant societal impact by creating natural hazards, such as earthquakes and mass earth movements, and controlling the distribution of natural resources such as fossil fuels or geothermal energy. This session aims to bring together researchers working in both the deep Earth and surface regimes.

Session 5: Deep cycles from the mantle to the crust

Co-Conveners: Jingsui Yang (Chinese Academy of Geological Sciences ), Yigang Xu (Guangzhou Institute of Geochemistry, CAS), Yongfei Zheng (University of Sciences and Technology of China) , Craig Schiffries (Carnegie Institution for Science, Washington, USA)

High-pressure and high-temperature experiments have significantly improved our understanding of processes that control the fate of crustal material in Earth’s mantle. This session aims to bring mineralogy, petrology, geochemistry, microstructure analyses, and numerical modeling together with high-pressure and high-temperature experiments to constrain deep geological cycles between the mantle and crust. These processes are recorded in the geologic record, including basalts, ophiolitic mantle rocks, ultra-high pressure metamorphic rocks, diamonds, subduction zones, and arc volcanoes. Geochemical data, including the isotopic composition of basaltic rocks, have revealed extensive modification of Earth’s mantle by the crustal material. Diamond is a messenger from earth’s mantle. Mineral inclusions as well as the carbon and nitrogen isotopic composition of diamond indicate that crustal material has been returned to Earth’s lower mantle, which is in agreement with seismic studies. Future research will improve our quantitative understanding of chemical mass transfer between the mantle and crust.

Session 6: Monitoring of active processes at depth

Co-Conveners: Harms, Ulrich (ICDP), Hailiang Dong (China University of Geosciences, Beijing), Barry Freifeld (Lawrence Berkeley National Laboratory, USA), Youhong Sun (Jilin University)

The joint action of North and South China Plate in eastern China, and particularly the influence of the west Pacific subduction belt, results in world class active faulting, volcanoes and earthquakes, large oil and gas basins, and deep carbon cycles. Thus, eastern China is an ideal area to observe, on a human time scale, material and energy exchange in the west Pacific subduction zone. However, a number of outstanding scientific questions remain such as earthquake nucleation, spreading, and termination; the chemical and biochemical pathways of biogenic and abiogenic hydrocarbons within deep Earth interior; deep microbial community and functions in different tectonic and crustal settings. Answers to these questions require delicate and complex instrumentations to monitor physical, chemical and biological processes within and across multiple deep boreholes. This session brings together expertise from various fields of geophysical, geochemical and biological instrumentations including (but limited to); electrical and magnetic properties, seismicity, gravity, temperature, pressure, lithology, and fluid composition. Both experimental and modeling approaches are welcome.

Session 7: Deep processes linked to formation of mineral resources

Co-Conveners: Zengqian Hou (NSFC and CAGS), Jingwen Mao(Institute of Mineral Resources, CAGS), John Thompson (Cornell University, Ithaca, USA), Qingtian Lyu (SinoProbe), Michael Dentith(University of Western Australia, Perth, Australia), Weidong Sun (Institute of Oceanology, CAS, Qingdao)

This section focus on topics include: lithospheric and upper mantle structure of the major metallogenic belt in China and around world; crust and mantle interaction and deep geophysical and geochemical processes that control the formation of mineral system; the basement and lower crust masses and their influence on metal type; the magma and the magma-fluid processes and their influence on mineral system; 3D architecture of major mineral districts and geophysical and geochemical signatures (footprint) of mineral system; and case studies on the above topics.

Session 8: Seismicity, volcanism and deep processes

Co-Conveners: Peizhen Zhang (CEA), Carlo Doglioni (University La Sapienza, Italy), Zhongliang Wu (Institute of Earthquake Forecasting, CEA), Mian Liu (University of Missouri, Columbia, USA), Gregory C. Beroza (Stanford University, USA) 

Deep processes related to seismicity and volcanism have both the spatial and temporal components, in which the temporal component may be more important for the monitoring and forecast of these geo-hazards. In recent years, emerging technologies have made it possible to detect, observe, and model the time-dependent deep processes related to the preparation and occurrence of earthquakes and volcanoes. Exchange of the up-to-date progresses in this field has clear implication for social sustainability, and for scientific understandings of the deep processes at different spatio-temporal scales.

Session 9: Emerging techniques for deep earth exploration

Co-Conveners: Fan-Chi Lin (University of Utah, USA), Qingyun Di (Institute of Geology and Geophysics , CAS), Yaoguo Li (Colorado School of Mines, USA), Changchun Yin (Jilin University)Huajian Yao (University of Sciences and Technology of China

Geophysical techniques are important tools for investigating the earth structures ranging from the near-surface to the upper mantle. However, traditional geophysical techniques for the deep earth encounter challenges due to weak signal,noise, limited depth of exploration, low resolution at depth. Thus, to study the deep-earth structures for exploration, monitoring and hazard assessment, advanced geophysical techniques are needed. We invite submissions related to recent developments in the exploration of deep-earth structures, mineral and oil and gas exploration, detection and development of urban underground, environment and natural hazard assessment, including but not limited to the modeling, instrument development, survey design, data processing, and inversion and interpretation. We also encourage case studies on the application of geophysical techniques in these areas.
