Abstract
We present a revised global plate motion model with continuously closing plate boundaries ranging from the Triassic at 230 Ma to the present day, assess differences between alternative absolute plate motion models, and review global tectonic events. Relatively high mean absolute plate motion rates around 9–10 cm yr-1 between 140 and 120 Ma may be related to transient plate motion accelerations driven by the successive emplacement of a sequence of large igneous provinces during that time. … Read more…

Earth's climate throughout the Phanerozoic

Eocene topo bath

Eocene topo bathProject Summary
EarthByte is involved in a series of projects aimed at understanding and modeling Earth’s climate throughout the Phanerozoic. Some of these projects include:

  • Future Fellowship of Maria Seton on “Oceanic gateways: a primary control on global climate change?”
  • Basin GENESIS Hub activities, related to the effect of the mantle, crustal deformation, erosion and sedimentary processes on sedimentary basins
  • ATOM – a coupled atmospheric-ocean circulation code jointly developed by Prof. Roger Grundmann and EarthByte.

EarthByte’s expertise in tectonics, geodynamics and surface process modeling is enhanced by close collaborations with leading palaeoclimate modellers and geochemical oceanographers.  … Read more…

Geochemistry, Geophysics, Geosystems – Community infrastructure and repository for marine magnetic identifications

magnetic_picks_globeMagnetic anomaly identifications form the primary data set from which the age of the oceanic lithosphere can be determined, a critical component of reconstructing the seafloor spreading history of ocean basins. This data is now available as part of an open source, community-driven online repository that contains quality-checked magnetic anomaly picks, organised by ocean basin and publication source.

Towards community-driven paleogeographic reconstructions: integrating open-access paleogeographic and paleobiology data with plate tectonics

PaleobioSummary
A variety of paleogeographic reconstructions have been published, with applications ranging from paleoclimate, ocean circulation and faunal radiation models to resource exploration; yet their uncertainties remain difficult to assess as they are generally presented as low-resolution static maps. We present a methodology for ground-truthing the digital Palaeogeographic Atlas of Australia by linking the GPlates plate reconstruction tool to the global Paleobiology Database and a Phanerozoic plate motion model.

We develop a spatio-temporal data mining workflow to validate the Phanerozoic Palaeogeographic Atlas of Australia with paleoenvironments derived from fossil data. … Read more…
