Joint meeting of GSC and GSA

17–19 June 2013  •  Chengdu, China  •  Jinjiang Hotel, Chengdu, Sichuan Province

Special Sessions

Topic A  |  Topic B  |  Topic C  |  Home

Topic B: Intra-continental deformation, mineral resources and geologic hazards
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.
