TL;DR: In this paper, the authors link East Gondwana spreading corridors by integrating magnetic and gravity anomaly data from the Enderby Basin off East Antarctica within a regional plate kinematic framework to identify a conjugate series of east-west-trending magnetic anomalies, M4 to M0.

TL;DR: In this paper, the authors present a new model that is constrained by revised seafloor spreading anomalies, fracture zones and crustal ages based on drillsites/dredges from all the abyssal plains along the West Australian margin and the Wharton Basin.

TL;DR: In this article, the authors assimilate geological and geophysical evidence into a plate tectonic model for the India-Eurasia collision that includes continuously closing topological plate polygons, constructed from a time-dependent network of evolving plate boundaries, with synthetic plates constructed for now-subducted ocean floor, including back-arc basins that formed on the southern Eurasian margin.

TL;DR: The origin of the Christmas Island Seamount Province in the northeast Indian Ocean is enigmatic. as discussed by the authors combine 40Ar/39Ar age, Sr, Nd, Hf and high-precision Pb isotope analyses of volcanic rocks from the province with plate tectonic reconstructions and find that the seamounts are 47-136 million years old, decrease in age from east to west and are consistently 0-25 million years younger than the underlying oceanic crust.

TL;DR: The southwest margin of Australia is a complex and poorly studied offshore continental region that includes the Perth and Mentelle basins as mentioned in this paper, and plate reconstruction and seismic data demonstrate that the margin comprises three major segments: the normal to oblique Mentelle and southern Perth margins and the Wallaby-Zenith Transform Margin.
