EarthByte Group develops machine learning recipe to find copper-gold deposits along the Andes

In a paper just published in the journal Tectonics, EarthByter and Natural Sciences, University of Sydney alumnus Nathaniel Butterworth and colleagues from the School of Geosciences, University of Sydney and Data61/CSIRO have developed a spatio-temporal machine learning recipe to identify subduction zone tectonic environments in which porphyry copper-gold deposits tend to form. The new approach … Read more…

The pains and strains of a continental breakup

View of Australia’s western continental margin, looking eastwards from the Indian Ocean. Every now and then in Earth’s history, a pair of continents draws close enough to form one. There comes a time, however, when they must inevitably part ways. Now scientists at Australia’s EarthByte research group, in collaboration with the German Research Centre for … Read more…

Summary
The supplementary data set comprise plate reconstructions from 130 Ma to present-day, designed to be used within the open-source reconstruction software GPlates.

There are eight sets of reconstructions. In each case, the relative plate motion (RPM) model is unchanged; the differences lie in the absolute plate motion (APM) model. This is expressed in the rotation file as the finite poles of rotation that describe motion of Africa relative to the Earth’s spin-axis. These files were the basis of the results presented in the EPSL paper.  … Read more…
