A GLOBAL DATABASE IN SEDIMENTARY PETROLOGY(SEDBA)

A global database in sedimentary petrology(SEDBA)was developed by IGCP Project 269 under the support of UNESCO-IGCP and IUGS. The author analized the significance of estab-lishing SEDBA,introduced the main achievement of IGCP Project 269 and described the charac-teristics and functions of SEDBA. According to the suggestion of sedimentologists at home and abroad,the author also proposed an imagine on developing SEDBA in the future,that is to de-velop the application of SEDBA in geosciences by realizing the connection and communication within different databases and by using the connected databases to solve actual geological prob-lems.
