Abstract
The Cenozoic evolution of South American topography is marked by episodes of large-scale uplift and subsidence not readily explained by lithospheric deformation. The drying up of the inland Pebas system, the drainage reversal of the Amazon river, the uplift of the Sierras Pampeanas and the uplift of Patagonia have all been linked to the evolution of mantle flow since the Miocene in separate studies. Here we investigate the evolution of long-wavelength South American topography as a function of subduction history in a time-dependent global geodynamic model. This model is shown to be consistent with these inferred changes, as well as with the migration of the Chaco foreland basin depocentre, that we partly attribute to the inboard migration of subduction resulting from Andean mountain building. … Read more…

Lord Howe Rise workshop JAMSTEC August 2015

A group of international scientists, including EarthByter Dietmar Müller, is gathering this week at the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) in Tokyo to put the finishing touches on an IODP proposal to drill through the Cretaceous stratigraphic section of the Lord Howe Rise (LHR), a submerged continental fragment that was once part of eastern Gondwanaland. The principal Australian agency in this collaborative project with JAMSTEC is Geoscience Australia, with Andrew Heap playing a leading role. The main emergent part of the LHR today is Lord Howe Island, an eroded remnant of a 7 million year old shield volcano, known to many Australians as a fine, but slightly pricey, getaway from the hustle and bustle of city life, full of kingfish, great beaches, a pristine coral reef and excellent outcrops of volcanic rocks and calcarenites. But what does not meet the eye is what lies underneath: several kilometers of Cenozoic and Cretaceous sediments that provide a rich record of subduction along eastern Gondwanaland, … Read more…

Good afternoon! On behalf of the University of Sydney and the School of Geosciences I welcome you to the opening of the ARC Research Hub for Basin GEodyNamics and Evolution of SedImentary Systems (in short Basin Genesis Hub).

Before we begin the proceedings, I would like to acknowledge and pay respect to the traditional owners of the land on which we meet – the Gadigal people of the Eora Nation. It is upon their ancestral lands that the University of Sydney is built.

I would like to extend a special thank you to our industry partners, Statoil, Chevron, Oil Search, Intrepid Geophysics and 3D-GEO, many of whom are here today. We are especially pleased to have with us today Ms Leanne Harvey, Executive General Manager of the ARC. … Read more…

Big data reveals geology of world’s ocean floor

6 September, 201510 August, 2015 by Michael Chin

A team led by the University of Sydney School of Geosciences has created the first digital globe of seafloor sediments.

Ocean sediments cover 70% of our planet’s surface, forming the substrate for the largest ecosystem on Earth and its largest carbon reservoir – but the most recent map of seafloor geology was drawn by hand over 40 years ago, at the dawn of modern ocean exploration.

That’s about to change. In a gargantuan effort Adriana Dutkiewicz and her colleagues carefully analysed and categorised 15,000 seafloor sediment samples to reveal the nature of sedimentary blankets over ocean ridges, seamounts and the vast abyssal plains. She teamed up with big data experts to find the best way to use modern computer algorithms to turn the vast sea of point observations into a continuous digital map. … Read more…

Dietmar Müller attends Australian open research data showcase in Canberra

17 October, 201519 June, 2015 by Michael Chin

Today Prof Dietmar Müller attended the Australian open research data showcase in Canberra. The showcase featured a variety of talks and discussions around the benefits and issues concerning open research data. It was an important milestone towards consolidating the Australian effort towards involving Universities and individual researchers in sharing their data.

A highlight was Ian Chubb’s presentation that pointed out that if you look at all papers published in the last 115 years, about 50% were either never cited or only cited once. The hope is that open access publications and associated open research data will improve these sorts of statistics. George Bernard Shaw was quoted by geologist Geoffrey Boulton (Univ. Edinburgh) as pointing out: “If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. … Read more…
