In a paper published in Nature, Rakib Hassan with fellow EarthByters Dietmar Müller, Simon E. Williams & Nicolas Flament, and Caltech’s Michael Gurnis, proposed a solution to a long standing geological mystery – how the distinct bend in the Hawaiian-Emperor Seamount Chain came to be. Using NCI’s Raijin supercomputer, the research team simulated flow patterns in the Earth’s mantle over the past 100 million years. The convection model suggests that the history of subduction has a profound effect on the time-dependent deformation of the edges of the Large Low-Shear Velocity Province (LLSVP) under the Pacific. The Hawaiian plume originates from the edge of this province and the southward migration of the plume during the formation of the Emperor chain reflects the migration of the northern edge of the LLSVP before ~47 million years ago.

Congratulations to Prof Dietmar Müller, Dr Nicolas Flament, Dr Kara Matthews, Dr Simon Williams, and Prof Michael Gurnis on their paper recently published in Earth and Planetary Science Letters. Their paper, Formation of Australian continental margin highlands driven by plate-mantle interaction, has featured in a variety of Australian and international media outlets.
Geologists from the University of Sydney and the California Institute of Technology have solved the mystery of how Australia’s highest mountain – Mount Kosciusko – and surrounding alps came to exist.
Most of the world’s mountain belts are the result of two continents colliding (including the Himalayas) or volcanism. The mountains of Australia’s Eastern highlands – stretching from north-eastern Queensland to western Victoria – are an exception. Until now no one knew how they formed.
The recent article on the GPlates Portal published in PLOS ONE by Prof Dietmar Müller, Xiaodong Qin, Prof David Sandwell, Dr Adriana Dutkiewicz, Dr Simon Williams, Dr Nicolas Flament, Dr Stefan Maus, and Dr Maria Seton, has received significant international media attention over the past week, featuring in articles from Australia, UK, US, India, and UAE!

How did Madagascar once slot next to India? Where was Australia a billion years ago?
Cloud-based virtual globes developed by a team led by University of Sydney geologists mean anyone with a smartphone, laptop or computer can now visualise, with unprecedented speed and ease of use, how the Earth evolved geologically.
Reported today in PLOS ONE, the globes have been gradually made available since September 2014. Some show Earth as it is today while others allow reconstructions through ‘geological time’, harking back to the planet’s origins.
Uniquely, the portal allows an interactive exploration of supercontinents. It shows the breakup and dispersal of Pangea over the last 200 million years. It also offers a visualisation of the supercontinent Rodinia, which existed 1.1 billion years ago. Rodinia gradually fragmented, with some continents colliding again more than 500 million years later to form Gondwanaland.

NASA Earth Observatory features a piece on the recent Mammerickx Microplate discovery. Their Image of the Day for 13 January 2016 is a satellite gravity map of the Indian Ocean, and the associated article, entitled ‘New Seafloor Map Helps Scientists Find New Features‘, discusses the power of satellite data for seafloor mapping and details the … Read more…
An article discussing GPlates and research that EarthByte is involved in has been featured on the IFL Science! website entitled ‘Incredibly Detailed, Billion-Year-Old Ancient Maps Of Earth Produced By Researchers‘.
Time machine: History and current advances in reconstructing the Earth through deep geological time – an article on Quartz by Steve LeVine. The article is a review of the development of ideas and technologies in reconstructing the Earth through deep time, aimed at understanding supercontinent assembly, breakup and dispersal, starting with Alfred Wegener. The article focusses on research activities in the context of the IGCP 648 project ‘Supercontinent Cycles and Global Geodynamics‘ led by Zheng-Xiang Li. The piece provides some historical context, and highlights the work of a number of leading scientists, postdoctoral researchers and PhD students currently involved in this work. … Read more…
