New interactive rift obliquity globe on the GPlates Portal

The ARC Basin Genesis Hub has made a new interactive rift obliquity globe available on the GPlates Portal at http://portal.gplates.org/cesium/?view=rift_ov, based on a recently published paper entitled “Oblique rifting: the rule, not the exception” in Solid Earth. This virtual globe visualizes extension velocities and obliquities within Earth’s major post-Pangea rift systems. Each circle depicts the … Read more…

Dietmar Muller gives public Accelerated Computing for Innovation talk on “Understanding Earth System Evolution – connecting Deep to Surface Processes”

The Earth’s composition and location relative to the sun has resulted in a thermal, structural and geochemical evolution that is unique in the solar system, forming a resource-rich, oxygenated habitable planet. Human civilization is built on the premise of relatively stable climate and coastlines Yet the geological record reveals numerous episodes of enormous change, innovation, … Read more…

The workshop was organised and delivered by Dr Sabin Zahirovic, Prof Dietmar Muller, and Dr Martina Ulvrova (ETH, Zurich), but also involved talented EarthByte students Amanda Thran and Wenchao Cao who helped users throughout … Read more…

GPlates 2.1 released (and pyGPlates revision 18)

GPlates Title Logo

GPlates 2.1 was released today! Many bugs have been fixed, including the computation of crustal thinning factors. NetCDF-4 is now supported for raster import/export, i.e. GPlates 2.1 can now read and write GMT-5 grids. Many thanks to the GPlates development team and especially to Sabin Zahirovic without whose tireless efforts GPlates 2.1 would not have … Read more…

GPlates: Building a Virtual Earth Through Deep Time

A paper about the GPlates software has been published in G-cubed. The GPlates virtual globe software provides the capability to reconstruct geodata attached to tectonic plates to develop and modify models that describe how the plates and their boundaries have evolved through time. It allows users to deform plates and to visualize surface tectonics in … Read more…

GPlates 2.1 software and data sets

GPlates Title Logo

GPlates 1.5 PromoGPlates is a free desktop software for the interactive visualisation of plate-tectonics. The compilation and documentation of GPlates 2.1 data was primarily funded by AuScope National Collaborative Research Infrastructure (NCRIS).

GPlates is developed by an international team of scientists and professional software developers at the EarthByte Project (part of AuScope) at the University of Sydney, the Division of Geological and Planetary Sciences (GPS) at CalTech, the Geodynamics team at the Geological Survey of Norway (NGU) and the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo. … Read more…

Kinematic constraints on the Rodinia-Gondwana transition. Precambrian Research. 299. . 10.1016/j.precamres.2017.07.013. Abstract: Earth’s plate tectonic history during the breakup of the supercontinent Pangea is well constrained from the seafloor spreading record, but evolving plate configurations during … Read more…

Rodinia conference in Townsville reviews progress and challenges in reconstructing ancient supercontinents

Several EarthByters presented talks at the Rodinia 2017 conference in Townsville, including Dietmar Müller, Andrew Merdith, Simon Williams, Mike Tetley and Nicolas Flament.  The conference was opened by two talks by Alan Collins (Univ. Adelaide) and Andrew, presenting their new Proterozoic Rodinia plate model with continuously closing plate boundaries that were recently published in Gondwana … Read more…

Workflow explained: The interaction of subduction zone volcanism with carbonate platforms and continents

Objectives Our two objectives of analysis were to (a) quantify the km-long length areas of interaction of subduction zone volcanism with carbonate platforms and (b) characterise the subduction volcanism as either continental or intra-oceanic depending on the proximity of the subduction zones to continent-ocean boundaries. In regards to the first objective, we are interested in cases where subduction-related … Read more…
