A synthesis of the available stratigraphic and foraminiferal evidence from the upper Cretaceous-Eocene sequence of various parts of the India-Pakistan-Burma region "shows that there were four main cycles of deposition. Each cycle is shown to have started with a transgression and ended with a regression. Evidence of minor local regression is present in some places. The earliest of these cycles ended with the Maestrichtian, and this is taken to indicate the end of the Cretaceous period. The next cycle strated with the Danian, which is now placed in the lowermost Tertiary (basal Paleocene), and continued into the Ranikot stage (Paleocene). The third and fourth cycles began with the Laki and the Khirthar stages, respectively, the two cycles together representing the whole of the Eocene."
