Special Symposia

1) Tectonics, climate, and sedimentation

SS1-1 Sedimentation in and around magmatic arcs in relation to tectonics and volcanism

This symposium will discuss the genetic relationship among tectonics, volcanism and sedimentation in and around the island arc region, and synthesize the evolution of island arc systems.

SS1-2 Monsoons and the Himalaya: tectonics-climate and land-ocean linkages

Linkages between the Himalaya-Tibet uplift and monsoon evolution, their impact on denudation, geomorphological evolution, and oceanography and sedimentation in the Asian continental margin and marginal seas are major topics of this symposium.

SS1-3 Continental margin sedimentation and deep-water sedimentary systems

Depositional systems of turbidite have been studied from the viewpoints of the earth's environmental changes, tectonics of sedimentary basins and hydrocarbon exploration. This symposium will focus on the recent progress and future potential of studies on deep-sea sediment in continental margins.

2) Environmental sedimentology and human society

SS2-1 Coastal environments and human activity

A better understanding of the coastal process in terms of deposition/erosion/transport is very important not only for sedimentology but also for human life. This symposium will focus on natural and anthropogenic changes in coastal environments, sediment-organism interaction, and coastal managements.

SS2-2 Catastrophic sedimentary processes: mechanisms and hazard mitigation

This symposium welcomes discussion on catastrophic sedimentary processes caused by earthquakes and volcanic eruptions. The rapid sedimentation/erosion/transport processes that cause such hazards as typhoons and mass wastings as well as their mitigation for human life are also discussed.

3) New targets and innovation in resource sedimentology

SS3-1 Gas hydrates: origin, exploration and resource potential

Huge amounts of methane are stored in the shallow geosphere as solid gas hydrates. This symposium discusses geophysical and geochemical explorations, and sedimentological studies of natural gas hydrates and ocean floor methane seeps, aiming at a better understanding of gas hydrates and an evaluation of their resource potential.

SS3-2 3D seismic technology for exploration and sediment body analysis

3D seismic data provide very important information on sediment-body configurations and reservoir distributions. This special symposium focuses on the analytical methodology, 3D seismic expression in various depositional systems, seismic geomorphology and case studies of hydrocarbon exploration.

4) Evolution of the biosphere and geosphere

SS4-1 Microbial processes and products in sedimentary systems

This symposium will focus on microbial sedimentary and biogeochemical processes and related products in near-surface and shallow- to deep-subsurfaces. Understanding the interaction between the biosphere and geosphere will create a new paradigm of sedimentology in the future.

SS4-2 Boundary events and global change

Mass extinction, oceanic anoxia and other environmental perturbations that affected the biosphere since 4.0 Ga are the main topics of this symposium. Possible causes of boundary events such as glaciations, volcanisms, bolide impacts, tectonics and dissociation of gas hydrates will be discussed.

5) Frontiers in sedimentology

SS5-1 Role of sedimentology in Earth drilling projects

Recently, the Integrated Ocean Drilling Program (IODP) and International Continental Scientific Drilling Program (ICDP) have provided us a good opportunity for resolving the scientific objectives of earth system sciences. In this symposium, we discuss the recent results of scientific ocean and continental drilling and new approaches, such as core-log-seismic integration.

SS5-2 Extraterrestrial sedimentology

Recent space missions successfully explore the solid surfaces of extraterrestrial bodies, including Mars, Venus, Galilean satellites, and minor bodies. This symposium integrates morphological and sedimentological studies of the earth and extraterrestrial bodies in order to understand the surface and evolutionary processes of those bodies.

SS5-3 Integrated strata analysis

Recent advances in strata formation and clinoform studies of continental margins using multi-approaches from modern processes, sedimentary records and modeling since the late 1990s have been giving us a better understanding of sediments and sedimentary rocks. This session will focus on such results and further integrated approaches.
