Scope Research for basin formation processes is inevitable to understand mass balance and circulation mechanism around surface of the globe. It also has an impact on pragmatic aspects such as resource exploration, disaster prevention and environmental assessment. Recent quantum leap in seismic and other geophysical survey techniques has enabled precise visualization of deep basin interior, and enhanced high-resolution stratigraphic and structural analyses. Moreover academic deep drilling projects provide us with an opportunity for detailed investigation of spatiotemporal distribution and evolutionary process of sedimentary basins. Reflecting such scientific and technical trends, quantitative numerical modeling approach is getting significant in the study field, which is thus facing substantial progress in methodology. Our session is focused on various types of basins on convergent plate margins. Under the influence of subduction modes of oceanic plates, they develop as a result of deformation of island arcs and/or continental margins, process of which has close linkage with tectonic events and eustatic sea-level changes. On the other hand, spatiotemporal variation of sedimentary basins is controlled by change in stress-strain regimes along a convergent margin, and gives us a clue to elucidate plate motion history. We expect interdisciplinary and ambitious papers containing latest research results.
