EarthByte offers spatio-temporal modeling resources to researchers and the public

by

In 2016, the EarthByte group, based in the School of Geosciences at the University of Sydney, created a visualization tool and model to measure the interactions of arc volcanism with buried carbonate platforms in deep time. The new workflow tools, which are available to the DCO community, enable scientists to approximate paleo-atmospheric CO2 flux within … Read more…

Model of Australia’s Tectonic Stress May Future-Proof Carbon Storage

by

In response to ever-rising carbon dioxide levels in the atmosphere, some countries are exploring carbon sequestration as a way to mitigate the effects of this greenhouse gas. The general strategy is to inject carbon dioxide more than a mile underground, beneath an impermeable rock layer, where it can dissolve into fluids and crystallize. Injection locations … Read more…

Curtin Basin Genesis Hub team scoops bronze in international geoscience awards

by

A team of students from the WA School of Mines, Curtin University, has picked up the bronze medal in the American Association of Petroleum Geologists (AAPG) Imperial Barrel Award competition in Houston, Texas. The Imperial Barrel Award (IBA) is an annual competition for geoscience graduate students from universities around the world, simulating the exploration work … Read more…

The effect of continental stress on carbon storage sites

by

Mitigating global warming by CO2 storage? Check for the continental stressitis. If proposed CO2 sites are not properly assessed for long-term stability,  future civilisations could still suffer the consequences of global warming. Professor Dietmar Müller from the School of Geosciences at the University of Sydney and Scott Dyksterhuis from ExxonMobil have created a computer model … Read more…

Zealandia: Earth’s Hidden Continent

by

ZealandiaA paper published in GSA Today, Zealandia: Earth’s Hidden Continent, by Nick Mortimer and colleagues, including EarthByte’s Dr Maria Seton, has gone viral over the last few days. In the paper, researchers have for the first time clearly defined Zealandia, a continent that includes New Zealand, New Caledonia, and the Lord Howe and Norfold Islands, that is today 94% submerged beneath the Pacific Ocean. According to GSA Today’s editors, the article is “by a long shot” their most downloaded article ever. Picked up by hundreds of media outlets worldwide, the findings of the paper has reached an estimated 720 million readers!

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.
