During the winter of 1984 work was begun on the Paleoceano graphic Mapping Project at the Institute for Geophysics, Univer sity of Texas, Austin, Texas. The goal of the Paleoceanographic Mapping Project (POMP) is to produce a set of maps and film animations illustrating the tectonic evolution of the ocean ba sins during the last 200 million years. The basis of these global reconstructions is a new digital data base of linear magnetic anomaly data and sea floor bathymetry. Initial support for the Paleoceanographic Mapping Project was received from British Petroleum, and as a result of their support a set of the Indian Ocean reconstructions were produced using a preliminary version of the POMP database. The six reconstructions described in this report represent the initial test of POMP data gathering procedures and mapping programs. The maps in this report are based on the published rotation parameters of Norton and Sclater (1979), Sclater et al. (1981 ), Scotese and Ross (1982), Fisher and Sclater (1983) (see Appendix I)., and represent our current understanding of the plate tectonic evolution of the Indian Ocean. These maps highlight the remaining problem areas, and serve as the starting point from which a revised set of Indian Ocean reconstructions will be produced.
