Tectonic speed limits from plate kinematic reconstructions

Abstract The motion of plates and continents on the planet’s surface are a manifestation of long-term mantle convection and plate tectonics. Present-day plate velocities provide a snapshot of this ongoing process, and have been used to infer controlling factors on the speeds of plates and continents. However, present-day velocities do not capture plate behaviour over … 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…

Colombia GPlates Course

During the second week of May, Earthbyte Alumnus Nicholas Barnett-Moore visited a research group at the National University of Colombia, Medellín, under the coordination of Assistant Professor Agustin Cardona and Associate Professor Gaspar Monsalve to teach a one-week intensive course on the plate reconstruction software, GPlates. The primary research interests of this group were focused … Read more…

A full-plate global reconstruction of the Neoproterozoic

Abstract Neoproterozoic tectonic geography was dominated by the formation of the supercontinent Rodinia, its break-up and the subsequent amalgamation of Gondwana. The Neoproterozoic was a tumultuous time of Earth history, with large climatic variations, the emergence of complex life and a series of continent-building orogenies of a scale not repeated until the Cenozoic. Here we … Read more…

pygplates beta revision 12 released

GPlates Vector Logo

GPlates Vector LogoThe first beta release of pygplates (the GPlates Python library) is now available for download.

pygplates enables access to GPlates functionality via the Python programming language. This may be of particular use to researchers requiring more flexibility than is provided by the GPlates user interface.

The following pygplates functionality is available:-

  • Load and save feature data (GPML, Shapefile, etc)
  • Create/modify/query feature data
  • Traverse/modify/query plate rotation hierarchy
  • Partition into plates and assign plate properties
  • Reconstruct geometries, flowlines, motion paths
  • Resolve topological plates and query their boundary sections (ridges/subductions)
  • Calculate velocities
  • Distance between geometries (region-of-interest queries)
  • Geometry queries (length, point-in-polygon, area, centroid, tessellate, interpolate, join, partition)
