6. Special Sessions
A-1: Evolution of the Qinghai-Tibet Plateau
Conveners: SMITH Alan, NIEMI Nathan MO Xuanxue (UGS-BJ), DING Lin (CAS)
Invited Speakers: COPLEY Alex, AVOUAC Jean-Philippe (Caltech), KLEMPERER Simon (Stanford) FREYMULLER Jeff (University of Alaska), KAPP Paul (UoA), XU Zhiqin (CAGS), WANG Chengshan (UGS-BJ), GAO Rui (CAGS)

The main focus of the session is to showcase the most recent advances in the studies of the Himalayan orogen and the Qinghai-Tibet plateau. Contributions from all aspects of Tibetan geology are welcome.

A-2: Continental deformation and deep lithosphere processes
Conveners: YIN An (UCLA), XU Zhiqin (CAGS), ZHANG Guowei (UNW)
Invited Speakers: DEPAOLO Don (UCB), KAPP Paul (UoA), MOLNAR Peter (University of Colorado), TAPPONNIER Paul, ALLMENDINGER Richard (Cornell University), FLESCH Lucy, BROWN Larry, DONG Shuwen (CAGS), ZHANG Peizhen (CEA)

The nature of deformation for continental lithosphere is one of the most fundamental problems of Earth Sciences. Asia has been a major testing ground in the past decades. This session intends to bring world-leading experts in studying intracontinental deformation to the meeting to discuss the current status of the problem.

A-3: Origin of ophiolites, podiform chromites, UHP minerals and tectonics

Conveners: YANG Jingsui, and ROBINSON Paul
Invited Speakers: DILEK Yildirim, YANG Jingsui (CAGS), JIN Zhenmin (UGS)

The discovery of in-situ diamonds, crustal minerals and highly reduced phases in chromitites of several ophiolites has many implications for the composition and processes and evolution of the upper mantle podiform chromitites containing inclusions of diamonds and other minerals likely formed in, or near, the mantle transition zone, which is also the ‘graveyard’ for subducted continental crust. These finding require a complete reexamination of current models for the formation of ophiolites and podiform chromitites and the stability of crustal minerals in the upper mantle. They also raise fundamental questions regarding the magmatic processes and melt-rock reactions in supra-subduction zone environments.

A-4: Foreland basin tectonics and sedimentation (north of the Tibetan Plateau)

Conveners: KHANDAKER Nazrul I., JIA Chengzhao (CNPC), LI Haibing (CAGS)
Invited Speakers: BUSBY Cathy, DECELLES Peter, CAROLLEL Alan, HENDRIX Marc,
FANG Xiaomin (CAS), WANG Erqi (CAS)

Foreland basins document active tectonism and provide significant constraints on depositional environments and resultant rock record. The Cenozoic geologic history of Tibet and surrounding regions is largely affected by complex plate-tectonic phenomena and many of these complex phenomena can be fingerprinted and explained by a combination of field, isotopic, and paleontological investigations. Geoscientists involved in field and simulation-based research are invited to submit papers for this session.

A-5: Deep Earth processes through geochemistry

Conveners: ZHANG Youxue, XU Yigang, ZHENG Jianping (UGA BJ)
Invited Speakers: RUDNICK R.L. (U Maryland), FEI Yingwei (Geophysical lab), ZHANG
Hongfu (CAS)

Petrological and geochemical studies often shed light on deep Earth processes. For example, petrology and geochemistry of large igneous provinces and hotspots may reveal mantle signature from the core-mantle boundary, and petrology and geochemistry of ultra-high-pressure metamorphic rocks can provide information on subduction and exhumation. This session will focus on solid Earth geochemistry, including igneous and metamorphic petrology, experimental petrology, trace element and isotope geochemistry, and mineral physics, and their applications to understand deep (from crust to the core-mantle boundary) Earth processes.

B-1: Intra-continental deformation [Active faults, earthquakes (e.g., Wenchuan)]

Conveners: BURCHFIEL Clark (MIT), ROYDEN Leigh (MIT), ZHANG Peizhen (CEA)
Invited Speakers: KIRBY Eric, BURBANK Doug, CLARK Marin, LI Haibing (CAGS), ZHANG Yueqiao (CAGS)

Since the collision of India and Eurasia about 50 Ma, India has India has indented Eurasia to form the highest area of topography on the Earth today. The processes of how the indentation has occurred are recorded in the intracontinental deformation within Eurasia as well as along the northern edge of the India indenter. Deformation within the collision zone has evolved over
time and is active today. This session will address the evolution of deformation within the collision zone and also the relation of the young and active deformation to geological hazards so prevalent in this part this part of the world.

B-2: UHP metamorphism, oceanic-continental subduction and collision

Conveners: LIOU J.G., ZHANG Ruyuan, ZHENG Yongfei (CUST), ZHANG Lifei (PU),
Invited Speakers: GILLOTTI Jane, DOBRZHINETSKAYA Larissa, HACKER Brad,YE Kai (CAS), LIU Fulai (CAGS), ZHANG Zemin (CAGS)

China contains at least 4 UHP terranes including the celebrated Dabie-Sulu, northern Qaidam, Tian-Shan and Himalaya their petrotectonic characteristics have been best documented. This session invites the latest data and concepts regarding to roles of fluid, and rates of subduction/exhumation of both continental and oceanic crust and mantle rocks and their contributions to geochemical recycling, and to explore new directions with novel or interdisciplinary techniques regarding the formation of UHP terranes in the Alpine-Himalayan sutures.

B-3: Sedimentary basins and oil-gas resources

Conveners: GRAHAM Steve (MIT), WEISLOGEL Amy, JIN Zhijun (Sinopec)
Invited Speakers: LIU Shaofeng (CUGB), HE Dngfa (Sinopec), ZHAO Wenzhi (CNPC), FENG Zhiqiang (SINOPEC), ZHANG Shuichang (SINOPEC), LEHRMANN Daniel (Trinity), JOHNSON Cari (Utah), ZHUANG Guangsheng (Yale), CARR Tim (WVU), CLIFT Peter (LSU), RITT Brad, COPE Tim

The tectonic and environmental processes that govern the evolution of basins and sedimentary systems have substantial implications for energy resource distribution in the subsurface as well as suitable reservoirs for geologic sequestration of captured CO2. This session will highlight the integration of data derived from study of complex basins in China and the U.S. that serve as the foundation for robust geologic models of basin formation and basin-fill.

B-4: Water resources, hydrogeology

Conveners: HARMON Russell SHI Jiansheng (CAGS)
Invited Speakers: WANG Yanxin(UGS-Wuhan), CHEN Zhongyu(CAGS), NORDSTROM
Kirk (USGS), ZHENG Yan. HU Bill (Florida)

Throughout northwest China, both surface and groundwater resources are recharged by water originating from glacial melt in mountain regions of the Qinghai-Tibet Plateau region and there is extensive transfer between rainfall, surface water, and ground water. Recent retreat of Tibetan Plateau glaciers as a consequence of global climate change are projected to have negative impacts across northwest China that include seasonal shifts in water supply for regional rivers and groundwater aquifers, increased precipitation variability, and enhanced flood risk. Additionally, the geochemistry and quality of both surface and ground waters are impacted by human activity in this arid area. This session will discuss the hydrogeology of northwest China and examine current water resources issues related to both global climate change and anthropogenic activity.

B-5: Mineral deposits in continents: Genesis and exploration

Conveners: MAO Jinwen (CAGS), CHEN Yanjin (PU), RICHARDS Jeremy (U Alberta),
CHI Guoxiang (U Regina)
Invited Speakers: HOU Zenqian (CAGS), HU Ruizhong (CAS), LEACH David
(USGS), GOLDFARB Richard (USGS), FAYEK Mostafa (U Manitoba)

The mineral deposits in continents are important metal sources for social developments. Important metallic deposits formed in continental environments include copper, gold and uranium deposits, occurring as porphyry (and/or skarn) copper, ultramafic-mafic intrusion-related Cu-Ni sulfides, epithermal Cu-Au, Carlin Au, orogenic Au, and sediment-hosted U. They are genetically related to subduction, collision (continent vs. continent, and continent vs. arc), post-collision and mantle plume environments. In the past ten years many new advances regarding ore-genetic processes, ore-forming settings, and ore-targeting technologies have achieved. The session will provide a new platform to exchange academic ideas and promote mineral exploration.

C-1: Critical transitions in the history of life and Earth

Conveners: XIAO Shuhai, ZHOU Zhonghe (CAS), JI Qiang (CAGS), CHEN Junyuan (CAS)
Invited Speakers: ERWIN Doug, LUO Zhe-xi (Chicago), SHU Degan (UNW), XU Xing
(CAS), JI Shuan (CAGS), CHEN Xu (Nanjing), RONG, Jiayu (Nanjing)

The history of life and Earth is defined by a number of critical transitions that had transformative impact on the evolutionary trajectory of our planet and its environment. This session invites presentations that focus on such critical transitions, particularly geobiological events that had a global impact on the climate, ocean, and atmospheric systems. Topics include, but are not limited to, the radiation of photosynthetic organisms, eukaryotes, biomineralizing organisms, animals, animal bioturbation, terrestrial animals and plants, mammals, flowering plants, as well as the assembly and collapse of ecosystems.

C-2: Mass extinction at the Permo-Triassic boundary and subsequent recovery dynamics

Conveners: YIN Hongfu (UGS-Wuhan), PAYNE Jonathan (Stanford), SHEN Shuzhong (Nanjing Institute)
Invited Speakers: XIE Shucheng (CUGS-Wuhan), SHEN Shuzhong (NJ-CAS), TONG Jinnan (Wuhan), WANG Xueqiu (CAGS), CLAPHAM Matthew (UC Santa Cruz), MEYER Katja (Stanford), BOWRING Sam (MIT), ELKINS-TANTON Lindy (Carnegie), ALGEO Tom (U. of Cincinnati), CHEN Zhong-Qiang (Wuhan), TONG Jinnan (Wuhan), LEHRMANN Daniel (Trinity University), LOOY Cindy (U.C. Berkeley), ALTINER Demir (Middle East Technical University, Ankara, Turkey), BASU A. R. (Rochester)

The mass extinction event at the end of the Permian Period eliminated a greater fraction of animal diversity than any event in the past 500 million years. The extinction and subsequent recovery dynamics also permanently altered the taxonomic composition and ecological structure of the biosphere. Many of the best paleontological records of extinction and recovery derive from stratigraphic sections in China and these have increasingly been coupled with high resolution studies of geochemical proxies that help to place biotic events within their local and global environmental contexts. This session will address patterns and processes of extinction and recovery from paleontological, sedimentary, geochemical, and geochronological perspectives. Particularly encouraged are contributions that seek an integrated biological and environmental understanding of extinction and recovery dynamics, and that highlight the ways in which this past catastrophe may help to inform our understanding of 21st century global change.

C-3: Carbon cycle and CO2 sequestration

Conveners: BURRUSS Robert C. (USGS), YUAN Daoxian
Invited speakers: ZHU Chen (Indiana), WARWICK Peter D. (USGS,), DING Zhongli, ZHANG Cheng (CAGS)

China and major industrialized nations worldwide are investigating options for reducing CO2 emissions to the atmosphere by CO2 sequestration. This session will cover a wide range of sequestration topics including estimation of sequestration capacities, hydrogeochemistry and geomechanics of CO2 injection, mineral sequestration in basalts and ultramafic rocks, sequestration and enhanced oil recovery, and carbon storage in ecosystems.`

C-4: Gas hydrates

Conveners: CHOU I-Ming, ZHANG Haiqi (CGS)
Invited Speakers: COLLETT Timothy (USGS), MORIDIS George (LBL), ZHU Youhai (CAGS)

Gas hydrates are potential energy sources for the future. The session will feature presentations on field, laboratory, and numerical modeling studies that enhance understanding of the interaction among sediment, hydrate, gas, pore fluids, and microbes for both marine and permafrost gas hydrate systems, especially those in US and China.
