Basin Genesis Hub computer model explains Early Cretaceous eastward flow of ancient Murray River

by

Murray_RiverAustralia is an outstanding natural laboratory to study the influence of dynamic topography on landscape evolution, having been largely unaffected by tectonic deformation since the Jurassic. Recent studies of the past eastern Australian landscape from present-day longitudinal river profiles and from mantle flow models suggest that the interaction of plate motion with mantle convection accounts for the two phases of large-scale uplift of the region since 120 Ma. … Read more…

Modelling and visualizing distributed compressional plate deformation using GPlates2.0: The Arctic Eurekan Orogeny

by

Gion_etal_figPresent-day distributed plate deformation is being mapped and simulated in great detail, largely based on satellite observations.  In contrast, the modelling of and data assimilation into deforming plate models for the geological past is still in its infancy.  The recently released GPLates2.0 software provides a framework for building plate models including diffuse deformation.  … Read more…

EarthByters find that death of ancient ocean between China and Russia triggered mantle upwelling

by

Flament_Figure5A collaboration between the University of Wollongong, the EarthByte Group at the University of Sydney, the California Institute of Technology and ETH Zürich have solved the mystery of the formation of a recently discovered structure 2,500 km below the city of Perm in Russia.

Earth’s lowermost rocky mantle, just above its iron-rich core, is characterised by two giant hot upwellings under the Pacific Ocean and Africa. Many islands in the Pacific and around Africa owe their volcanic activity to “hotspots” within these large, hot regions deep underneath the surface.  … Read more…

Augury Geodynamics team visits Earthbyte Group in December 2016 in the quest towards Plate Tectonics 2.0

by

Augury-EarthByte cutout.jpgOur geodynamics collaborators from the Augury Geodynamics Group, Univ. Lyon, are spending the month of December 2016 with the EarthByte Group  to collaborate on a range of issues revolving around seeking improved connections between kinematic (plate tectonic) and dynamic Earth models to advance our understanding and knowledge of the evolution of the solid Earth and the “rules of plate tectonics”. Even though some basic rules of plate tectonics have been accepted since the 70s, these rules are not extensive enough to understand the dynamic, time-dependent interaction between the convecting mantle and the tectonic plates.  The visit is inspired by the move towards Plate Tectonics 2.0 – the development of a unified conceptual and methodological framework to understand how the shallow crust, landscapes, continental margins, and ocean basins interact with the coupled non-linear evolution of the plates and deep Earth through time.

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

by

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 could pave the way for future mineral discoveries.

GPlates 2.0 software and data sets

by

GPlates 1.5 PromoGPlates is a free desktop software for the interactive visualisation of plate-tectonics. The compilation and documentation of GPlates 2.0 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…

Surface Processes Modelling Workshop

by

Badlands imageThe EarthByte Group will conduct a 2 days workshop on surface processes modelling on the 13th and 14th of October in the Madsen Building at the School of Geoscience, The University of Sydney, Australia.

The workshop aims to introduce those interested in landscape evolution and source to sink problems to a new open-source code: Badlands. Note that you do not have to be a seasoned modeller to participate. Geomorphologists, tectonicists and sedimentologists interested in testing conceptual models based on field observations are welcome! … Read more…

Date:  August 29 – 30 2016 Venue: The University of Sydney Description: A two-day workshop bringing together climate and geo-scientists from around Sydney and international collaborators on the DCO-funded Deep Carbon Modelling project. Deep carbon science describes the multi-disciplinary effort to unravel the dynamic interactions of carbon-bearing systems in deep time. The workshop will focus on exploring the interplays … Read more…

Taking the pulse of the global ocean

by

sediments_currents_global_oceanWhen organic particles sink from the surface ocean to the seafloor, a small but significant proportion of atmospheric carbon is stored away. Adriana Dutkiewicz and colleagues at the University of Sydney and Data61/CSIRO have now used global data sets collected over decades combined with cutting-edge big data analysis to understand how this process depends on surface ocean environments.   … Read more…

Commotion in the deep Southern Ocean

by

souther_ocean_circulationCongratulations Adriana Dutkiewicz, Dietmar Müller, Andrew Hogg, and Paul Spence for their recent paper published in Geology. Their paper, Vigorous deep-sea currents cause global anomaly in sediment accumulation in the Southern Ocean, revealed an enormous stretch of the Southern Ocean where sediments are building up at a rate that dwarfs other deep ocean locations. The work has attracted the attention of media internationally. … Read more…

The pains and strains of a continental breakup

by

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 Geosciences, have revealed the underlying mechanics of a continental breakup when this … Read more…
