Boulder, Colorado, USA – The April/May GSA Today science article is now online at www.geosociety.org/gsatoday/. In this issue, Simon Williams and colleagues from the Earthbyte Group of the School of Geosciences at the University of Sydney present GPlates, a powerful new method for analyzing geological and geophysical data sets within the context of tectonic reconstructions.
GPlates is part of a new generation of plate reconstruction software that incorporates functionality familiar from GIS software with the added dimension of geological time. By enabling the user to rapidly visualize a diverse range of geological and geophysical constraints within different tectonic reconstructions, the implications of different tectonic models for reconciling a variety of observations can be investigated with ease, allowing more informed choices to be made between different models and data. To illustrate the application of this software, the authors explore alternative tectonic models for the assembly of Western Australia and the configuration of Rodinia by using GPlates to reconstruct geological terranes, geophysical grids, and paleomagnetic data relevant to the reconstructions.
