Abstract:

Sedimentological research is highly relevant to human survival and mineral resource exploration and exploitation. In this paper, we briefly analyzed the rearch hotspots in sedimentological researches both at home and abroad by examining the recent 200 years of research history. The International Association of Sedimentology has paid much attention to the IODP, deep-time climate and global sea level changes, source-to-sink system, carbonate sedimentary environment, mixed clastic-carbonate sedimentation, microbialite, shelf edge delta, gravity flow, fine-grained sedimentation, tectono-sedimentology, and volcanic and seismic sedimentology. While Chinese sedimentologists have focused on continental sedimentation, sedimentary models of continental basins, sedimentology of the South China Sea, sedimentary process of different types of basins in China, shallow and shelf edge deltas, source-to-sink systems of different sizes and geological ages, and carbonate deposits in small cratonic basins of southern China. Presently, the major global sedimentological research hotspots include continental sedimentology, onshore and shallow-water deposits, deep-water sedimentation and event deposits, carbonate sedimentation, sedimentary process and new methods. Future areas of sedimentological research development in China shall include theory of sedimentary dynamics of different petroliferous basins, regional characteristic continental sedimentology, multi-disciplinary approach, quantitative sedimentology, and new research methods. Sedimentology as a very important discipline of geology can guide more efficient hydrocarbon prospecting and exploration.
