Abstract:
The junction between the Tethys and Panthalassa oceans is one of the most ill-constrained portions of Cretaceous palaeogeographic maps due to a lack of preserved in-situ oceanic crust from this region. Yet the development of this junction along the northern margin of the Australian plate impacts on our understanding of the Cretaceous evolution of the entire northern and eastern margin of Australia. The present-day tectonics of the region (Fig. 1) is dominated by the collision of the Australian plate along Papua New Guinea, the extrusion of the Sundaland block, and the complex arrangement of plate boundaries in SE Asia, with no clear connection between the Indian and Pacific oceans.
