| 摘 要： | The Commission for the Geological Map of the World (CGMW), an IUGS affiliated body, has just issued the first edition of the Structural Map of the Indian Ocean which was presented during the 32nd IGC (Florence). During the 1980‘s, the Commission published the Geological Atlas of the World, which included the maps of the 5 oceans of the globe. Two decades have elapsed and the knowledge of the sea-floor experienced very significant progress; therefore some 5 years ago, the Commission decided to launch a new type of ocean mapping. The Structural Map of the Indian Ocean is the first of this new series of maps.
