Abstract  

The present contribution is a report submitted to the IODP-China office by the authors, after the implementation of the Integrated Ocean Drilling Program (IODP) Expedition 333. The objectives of this cruise are to drill at three sites along a transaction in the northern Philippine Sea, within the framework of the NanTroSEIZE program. The drilling operation was carried out from  December 12, 2010 to January 10, 2011, and cores with a total length of 1 005 m were obtained. These cores provide the materials to study the Quaternary sedimentary processes and mass transport deposits associated with the slope basin, deep trench and sea mount environments. Laboratory analyses will be carried out to obtain information on pore pressure within the sediment, heat flux, clay mineralogy, micro-structures, and tephra stratigraphy. On such a basis, the influence of the accretionary prism on the stress distribution and the critical stress for the occurrence of large-scale earthquakes may be evaluated. Furthermore, the cores enable the researchers to seek solutions to other scientific problems, such as the formation of deep water fine-grained sediment deposits, periodicity of volcano activities, the mechanisms for the formation deep sea green muds, the vertical distribution patterns of sedimentary structures and the related processes,  deep water sediment transport processes and the resultant geomorphological evolution during the Quaternary period.

Key words:  Seismogenic Zone Experiment      Accretionary prism      Mass transport deposits      Deep water Quaternary sedimentation      IODP      Northern Philippine Sea.
