Abstract The current research hotspots and advances of international sedimentology has been analyzed based on the data of 19th International Sedimentological Congress,which indicates that global climatic sedimentary record,deepwater sedimentology and event deposition,and carbonate and microbial sedimentology are becoming the three current hot issues in sedimentology besides the continual hot topic: resources sedimentology. Main progresses in global climate sedimentary record came from sedimentary recorders exploration for detailed climate change,climatic environmental and ecological effects and the climate macro-change rules of deep time in a special geological time or a special geological realm. Main advances in deepwater sedimentology and event deposition were embodied in sedimentary process study,such as hydraulic jump and field monitoring of deepwater sedimentary process,and event deposition triggered by earthquake,tsunami,flood,volcanic,etc.,and the turbidite prediction and hydrocarbon exploration. Advances in carbonate and microbial sedimentology were expressed in cold water carbonate deposition and microbial controls on carbonate deposition. Comparison shows that sedimentary study in China focuses on continental facies such as fluvial and lacustrine but seldom on eolian,glacier and coastal environment;focuses on applied resource sedimentology and so forth,but rarely on basic scientific problems such as sedimentary dynamic process study in terms of the study objectives;focuses more on deepwater sedimentation and unconventional resource geology in three hot issues,but confined them to the sedimentary phenomenon description,hydrocarbon exploration and development. Finally,the authors suggest that three breakthrough directions possibly come from more attentions paid to sedimentary dynamic process and source-channel-sink system analysis,and timely introduction of the deepwater and cold carbonate sedimentation and biological geology theory,and global climate change studies with full-use of a large number of scientific drillings and wells information from oilfield drilling.
