Advance on Sedimentology and Sequence Stratigraphy:A Summary from 18th International Sedimentology Congress

Key words: 
• sedimentology

Abstract: Advance on sedimentology and sequence stratigraphy were summed up in view of point from oil and gas exploration in petroliferous basins. It included as follows: the third order sequence and types of systems tract and its significance of petroleum geology; sequence stratigraphic application in unconventional oil and gas exploration; palaeosoil and trace fossils and its significance in sequence identification; basin types and depositional systems including basin fills such as tectonic, climate and deposits, foreland basin deposits, faulted basin deposits, stripslide basin deposits etc., as well as depositional sequence of clastic system such as lacustrine, glacial and eolian system； deep water sedimentology； basin analysis and resource sedimentology including coal, oil and gas, placer mine, source rocks and reservoirs etc. ; volcanic rocks reservoirs including volcanic deposits, volcanic eruption, volcanic diffusion and facies model； element geochemistry including clastic geochemistry such as diagenetic petrology, clastic petrology and geochemistry, provenance and weathering, and clay mineral geochemistry；and advance on carbonate rocks sedimentology including microbial carbonate sedimentology, mixed carbonate and clastic rocks, cold water carbonate rocks, and diagenetic changes and geochemistry of carbonate rocks. It also finally points out that future emphasis in oil and gas exploration focus on outcrops and modern deposits research, laboratory technique and sedimentary geochemistry, laboratory model and numerical simulation, and sequence stratigraphy and foreland basin analysis.
