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)

Ancient Indian Ocean microplate discovery dates birth of Himalayas

Mammerickx Microplate

Mammerickx MicroplateAn international team of scientists led by the University of Sydney’s School of Geosciences has discovered that the crustal stresses caused by the initial collision between India and Eurasia cracked the Antarctic Plate far away from the collisional zone and broke off a fragment the size of Tasmania in a remote patch of the central Indian Ocean.

The ongoing tectonic collision between the two continents produces enormous geological stresses that build up along the Himalayas and lead to numerous earthquakes every year – but now scientists have unravelled how stressed the Indian Plate became 47 million years ago when its northern edge first collided with Eurasia. … Read more…

Below are some details about Nico’s project (2016-2019) entitled ‘The geodynamics of past sea level changes‘:

This project is designed to quantify the effect of flow deep within Earth’s interior on past sea-level changes and on the flooding history of Australia over the last 550 million years. The rise and fall of sea level has shaped our planet over time. This project plans to combine recent advances in tectonic reconstructions and dynamic Earth models with the global and Australian rock record. … Read more…
