Schedule of Technical Sessions (PDF)

Theme 1:
Siliciclastic depositional systems and sequence stratigraphy

Sequence stratigraphy and depositional systems analysis have become inextricably linked over the past decade or so. This session, therefore, will focus on how this linkage has significantly advanced both scientific disciplines, and how we increasingly are able to identify the external drivers (processes) reflected in stratal architecture and sedimentary attributes. Sea level changes, global and local climate variations, and tectonism on different spatial and temporal scales, are of course some of the most fundamental of these drivers, and will be explored in depth by the many discussions of this theme.

Conveners:
D. Nummedal (CSM), V. Abreu (ExxonMobil), A. Schaefer (Univ. Bonn), A.T-S. Lin (Nat. Central Univ.), T. Sakai (Shimane Univ.) and K. Hoyanagi (Shinshu Univ.)

TS1-1 Glacial depositional systems
TS1-2 Aeolian systems
TS1-3 Lacustrine and fluvial systems
TS1-4 Barrier island and estuarine systems
TS1-5 Delta and fan delta systems
TS1-6 Shelf and shallow marine systems
TS1-7 Resedimentation and deep-water sedimentary systems
TS1-8 Sea-level changes and sequence architectures

Theme 2:
Carbonates and evaporites

The carbonate deposits record many geo-scientific events: vertical and lateral tectonic movements, sea-level fluctuations, palaeoclimatic changes, palaeoceanographic variations, hydrologic conditions, and mass extinctions and evolution of organisms. This session will focus on the various events detected by carbonate sedimentological and geochemical studies. Fundamental investigations on depositional processes and diagenesis of carbonate rocks are also welcome.

Conveners:

Theme 4:
Basin analysis and numerical modelling

This theme focuses on the evolution of sedimentary basins in tectonically active settings. The session will integrate onland and oceanographic studies of modern active margin basins, which provide detailed "snapshot" views, with outcrop and subsurface studies of ancient basins, which provide a time-intregrated view. Possible topics include (but not restricted to): sedimentary response to the growth of structures; controls of basin architecture on depositional systems and systems tracts; significance of unconformity surfaces; volcanic and volcaniclastic facies analysis; and modeling of transport-depositional systems as well as subsidence and sedimentation patterns.

Conveners:
C. Busby (UCSB), C. Paola (Univ. Minnesota) and O. Takano (JAPEX)

TS4-1 Tectonics and sedimentation
TS4-2 Basin analysis and stratigraphic modeling

Theme 5:
Petrology, mineralogy and geochemistry of sediments

This session seeks to integrate a variety of approaches to understanding the composition, mineralogy and geochemistry of sediment and sedimentary rocks. The coverage includes sedimentary provenance, compositional and mineralogical changes in sedimentary environments, diagenesis of clastic sediment, chemostratigraphy and others. Topics may include a wide spectrum of various sedimentological, geological and environmental aspects.

Theme 7:
Marine geology and sedimentology

Recent research on the sedimentary processes of modern continental shelves has greatly benefited from new technologies such as multibeam sonar, the acoustic Doppler current profiler and instrumented sediment transport platforms. Important advances are being made in the understanding of coastal and shelf processes and morphology, particularly in relation to determining sediment transport pathways, bedform morphometry and exchange of sediment between the coast, continental shelf and slope. This session provides a venue for researchers to present recent results and share new concepts on shelf sediments and sedimentary process studies.

Theme 10:
Resource sedimentology

Sedimentology has contributed to stable supply of essential resources to the world. Recent improvements of sedimentology integrated with high technologies of the other fields (e.g. satellite images, electrical survey, seismic survey, well data, geostatistics, numerical models etc.) help people to reduce uncertainties regarding distribution of the resources and produce them effectively. Importantly such an effective detection tool based on sedimentology lead us to exploit resources in environmentally-friendly. This session provides venues and case studies about utilities of sedimentology for effective resources production to discuss possible ways of resources sedimentology for the future.

Friedman, former president of the IAS, will give us a history of IAS. In addition, we welcome any facts and stories about the history of sedimentology from any place in the world. Discussions and advertisements of new methods and technology are welcome at the sub-session TS12-2. Sub-sessions TS12-3 and TS12-4 relate to the Special Symposia SS5-1(Role of sedimentology in Earth drilling projects) and SS5-2(Extraterrestrial sedimentology). Related voluntary discussions for the poster presentation are also welcome.
