Rift and plate boundary evolution across two super-continent cycles

by

Abstract The extent of continental rifts and subduction zones through deep geological time provides insights into the mechanisms behind supercontinent cycles and the long term evolution of the mantle. However, previous compilations have stopped short of mapping the locations of rifts and subduction zones continuously since the Neoproterozoic and within a self-consistent plate kinematic framework. … Read more…

Australian-Antarctic breakup and seafloor spreading: Balancing geological and geophysical constraints

by

Abstract  The motion of diverging tectonic plates is typically constrained by geophysical data from preserved ocean crust. However, constraining plate motions during continental rifting and the breakup process relies on balancing evidence from a diverse range of geological and geophysical observations, often subject to differing interpretations. Reconstructing the evolution of rifting and breakup between Australia and Antarctica epitomizes the challenges involved in … Read more…

Does the sea level or the sun drive volcanic seafloor topography?

by

Modelling shows what causes abyssal hills 2.5km below sea level Computer modelling shows climate- and sea-level cycles are not responsible for the ‘hills’ and ‘valleys’ at the bottom of the sea – a hypothesis that would have mapped a path to uncovering Earth’s climate history. Half a century after discovering how plate tectonics works, the … Read more…
