In the piece, Patrice recalls some of his own experiences as a kid when he first encountered mountain building. He wrote: “Hello Astrid. You may not believe this but when I was about your age my teacher (Mr Rouve) explained to the class how mountains get made. He took a sheet of paper and put … Read more…
Roberto Spina, a computational geologist from Italy, wrote a lead article in GSA Today, in which he reviews the future of Big Data and Artificial Intelligence Analytics in Geosciences, using Adriana Dutkiwicz’s digital seafloor lithology map published 3 years ago as a ground-breaking example. The article includes a South Atlantic view of the virtual globe portraying her map, … Read more…
Ready for a fresh start in 2019, our web development guru Michael Chin has created a new interactive virtual gravity globe, based on BGI’s global gravity grids by Bonvalot et al. (2012). The virtual globe allows the user to visualise either Bouguer or isostatic gravity anomalies. The latter has both the effect of surface and … Read more…

Abstract The extent of continental rifts and subduction zones through deep geological time provides insights into the mechanisms behind supercontinent cycles and the long term evolution of the mantle. However, previous compilations have stopped short of mapping the locations of rifts and subduction zones continuously since the Neoproterozoic and within a self-consistent plate kinematic framework. … Read more…
EarthByte would like to welcome Edward Clennett from the University of Oxford who is visiting us for 5 weeks to work on his masters project. During his visit, he plans on developing a new plate reconstruction model of the north-eastern Pacific and western North America using tomographic constraints and terrane accretion events. He will also … Read more…
Abstract The motion of diverging tectonic plates is typically constrained by geophysical data from preserved ocean crust. However, constraining plate motions during continental rifting and the breakup process relies on balancing evidence from a diverse range of geological and geophysical observations, often subject to differing interpretations. Reconstructing the evolution of rifting and breakup between Australia and Antarctica epitomizes the challenges involved in … Read more…

The ARC Basin Genesis Hub has made a new interactive rift obliquity globe available on the GPlates Portal at http://portal.gplates.org/cesium/?view=rift_ov, based on a recently published paper entitled “Oblique rifting: the rule, not the exception” in Solid Earth. This virtual globe visualizes extension velocities and obliquities within Earth’s major post-Pangea rift systems. Each circle depicts the … Read more…
Five University of Sydney researchers have been recognised for their work by the NSW Premier Gladys Berejiklian. Amongst them was Dietmar Muller who received the NSW Premier’s Prize for Excellence in Mathematics, Earth Sciences, Chemistry or Physics at an awards ceremony held at Government House. http://www.chiefscientist.nsw.gov.au/premiersprizes/2018-category-winners This is a marvellous recognition of the fundamental role … Read more…
Congratulations to Prof Dietmar Muller who has been awarded the Excellence Professor Award from the German Petersen Foundation for 2019. The award comes with €20,000 (about AU$32,000) and an invitation to spend 6-8 weeks at GEOMAR in Kiel to present a series of lectures, a short course, and to continue/launch collaborations in the field of marine geoscience. … Read more…
Long-term EarthByte collaborator Kaj Hoernle has been awarded the Gustav Steinmann Medal at the recent annual meeting of the German Geological Society. The medal, which has been awarded since 1938, honours outstanding overall achievements in the geosciences. Kaj studied geology, petrology and geochemistry at Columbia University and at UC Santa Barbara. Since 1994 he has … Read more…
The Earth’s composition and location relative to the sun has resulted in a thermal, structural and geochemical evolution that is unique in the solar system, forming a resource-rich, oxygenated habitable planet. Human civilization is built on the premise of relatively stable climate and coastlines Yet the geological record reveals numerous episodes of enormous change, innovation, … Read more…

Modelling shows what causes abyssal hills 2.5km below sea level Computer modelling shows climate- and sea-level cycles are not responsible for the ‘hills’ and ‘valleys’ at the bottom of the sea – a hypothesis that would have mapped a path to uncovering Earth’s climate history. Half a century after discovering how plate tectonics works, the … Read more…

A paleo-digital elevation model (paleoDEM) is a digital representation of paleotopography and paleobathymetry that has been “reconstructed” back in time. This report describes how the 117 PALEOMAP paleoDEMS (see Supplementary Materials) were made and how they can be used to produce detailed paleogeographic maps. The paleoDEMS describe the changing distribution of deep oceans, shallow seas, … Read more…

About 250 million years ago, a massive volcanic eruption flooded modern-day Siberia with lava, creating the Siberian Traps, giant plateaus made of multiple layers of lava. The eruption also released huge quantities of carbon dioxide into the atmosphere that rapidly altered the climate and triggered the Permian-Triassic mass extinction event that wiped out more than … Read more…
