10 Introduction to the SinoProbe The SinoProbe Deep Exploration in China, is a multidisciplinary earth science program in China, with the all aim to reveal the composition, structure and evolution of the continental lithosphere beneath Chinese continent, and promote capabilities of the scientific research and understanding of the Earth, exploration of natural resources, and early warning of geo-hazards.
11 Introduction to the SinoProbe The SinoProbe started in The first 5 years from is the initial phase of the SinoProbe, which is aimed at the testing of the feasibility of deep exploration technologies in geophysics, geochemistry, and continental deep drilling in China. The procedure of data collection and processing, and also the deep exploration instruments is developed in this phase. The other important goal is educating and training the new generation scientists for the launching of the SinoProbe program in full scale in the future. The total budget of the SinoProbe is ca. $200M for
12 Key Scientific Problems China occupies a large region of central and eastern Asia and holds key to resolve several first-order problems in Earth Sciences. Does continental lithosphere deform fundamentally in a plate-like or fluid-like fashion during continent-continent collision? Did the development of the Paleo- and Neo-Tethys and Paleo-Asia Oceans contribute to significant Phanerozoic production of continental crust in Earth's history? How did the uplift of the Qinghai-Tibet plateau control the regional and global climate change and biological evolution? How deformation of Tibet Plateau responded on driver from India and Western Pacific plates? What kind structure of lithosphere in east Asia influenced on formation and distribution of larger ore deposits and mechanism of earthquakes and geohazards?
13 Broad-band seismic stations with a total number of 585 and deploying length of 7300 km, paralleling to deep seismic reflection profiles. Deep seismic wide-angle reflection and refraction profiles with a total length of ca km. MT sounding with a total number of 1229 and length of 3300 km. Big Data: Nation-Wide Geophysical Data Deep seismic reflection profiles with a total length of ca km, crossing major orogens and basins in the Qinghai-Tibetan Plateau, the South China, the North China, and the Northeastern China. Up to 10 TB
14 Big Data: Nation-Wide Geophysical Data Dense 1 1 MT Standard Array observations: the North China (115 sites and 1386 physical points) and the Qinghai-Tibetan Plateau (88 sites and 874 physical points).
