南海海盆的深部结构和扩张过程的集成研究

“南海深部计划”以南海为突破口，探索边缘海盆地演化与运行系统，树立边缘海研究典范。在“构造与岩浆活动”方向，南海深部计划已经支持15个专题项目，获得重要的阶段性成果。本方向中后期研究的重点是开展一系列集成活动，最大程度地促进各项目团队间的交流合作，以求在三大科学问题上取得突破性进展：（1）南海海盆扩张过程、（2）南海海盆的深部结构、（3）南海与全球其他边缘海的异同。本集成项目将建设三个合作创新平台：（1）交流与讨论平台：举办专题论坛与研讨会、整合论文专辑、促进团队间讨论以及协办学术年会等。（2）数据库平台：建立第一个本方向的南海综合数据库，收录南海深部计划支持项目、IODP、NGDC、 MGDS等重要来源的数据，促进创新研究，同时建立集成研究网站。（3）定量模拟平台：促进南海构造与岩浆研究的定量模拟，提高各团队定量模拟能力，举办国际培训班、建设模拟交流平台、促进交叉学科模拟等。

The South China Sea Deep (SCSD) Program is planned to reconstruct the tectonic and environmental history of the South China Sea (SCS), making it one of the best-investigated marginal seas. The overarching goal of this Integration Project (2016-18) is to advance our understanding of the fundamental processes of SCS basin evolution, mantle dynamics, and crust accretion. Our overall strategy is to organize a series of community-wide research-related activities that will help to maximize the interactions among research groups/scientists, leading to innovative cross-disciplinary research collaboration. More specifically, we plan to implement three types of community-wide Integration Tasks: (1) Maximize Community-Wide Interactions. We plan to organize a series of special topic symposiums/workshops, working-group meetings, and small working sessions among individual researchers. These activities will help to promote new cross-disciplinary researches. (2) Build a SCS Tectonics/Magmatism Database. This will be the first community-based SCS database focusing on science theme of tectonics and magmatism. The database will include comprehensive data holdings in geophysics, geochemistry, and ocean drill data, with data sources from participating institutions, projects supported by the SCSD, as well as internationally-available data of IODP, NGDC, and MGDS. This new database will facilitate new innovative research. (3) Construct Improved Marginal Basin Conceptual Models. On the basis of recent major progress in investigating the SCS tectonics (IODP Exp. 349 in 2014, deep-tow magnetics, 3D mantle and crustal seismic experiments, scheduled IODP 367/368 in 2017, etc.), we see exciting opportunities for constructing significantly improved conceptual models of marginal sea evolution with the SCS as a classic example. We also plan to organize a number of training courses on the state-of-the-art quantitative modeling approaching, inviting the best international scientists as instructors and aiming at training young scientists and graduate students. It is anticipated the above designed Integration Tasks will significantly facilitate cross-disciplinary collaboration, maximize community interaction, promote innovative conceptual models of marginal sea evolution, and thus make the SCS as one of the best investigated marginal seas.
