Ancient Indian Ocean microplate discovery dates birth of Himalayas

10 June, 201611 November, 2015 by kara

An international team of scientists led by the University of Sydney’s School of Geosciences has discovered that the crustal stresses caused by the initial collision between India and Eurasia cracked the Antarctic Plate far away from the collisional zone and broke off a fragment the size of Tasmania in a remote patch of the central Indian Ocean.

The ongoing tectonic collision between the two continents produces enormous geological stresses that build up along the Himalayas and lead to numerous earthquakes every year – but now scientists have unravelled how stressed the Indian Plate became 47 million years ago when its northern edge first collided with Eurasia. … Read more…

Abstract
We present a revised global plate motion model with continuously closing plate boundaries ranging from the Triassic at 230 Ma to the present day, assess differences between alternative absolute plate motion models, and review global tectonic events. Relatively high mean absolute plate motion rates around 9–10 cm yr-1 between 140 and 120 Ma may be related to transient plate motion accelerations driven by the successive emplacement of a sequence of large igneous provinces during that time. … Read more…

Abstract
There has recently been a rapid growth in the amount and quality of digital geological and geophysical data for the majority of the Australian continent. Coupled with an increase in computational power and the rising impor- tance of computational methods, there are new possibilities for a large scale, low expenditure digital exploration of mineral deposits. Here we use a multivariate analysis of geophysical datasets to develop a methodology that utilises machine learning algorithms to build and train two-class classifiers for provincial-scale, greenfield min- eral exploration. … Read more…

Abstract
Knowing the patterns of distribution of sediments in the global ocean is critical for understanding biogeochemical cycles and how deep-sea deposits respond to environmental change at the sea surface. We present the first digital map of seafloor lithologies based on descriptions of nearly 14,500 samples from original cruise reports, interpolated using a support vector machine algorithm. We show that sediment distribution is more complex, with significant deviations from earlier hand-drawn maps, and that major lithologies occur in drastically different proportions globally. … Read more…

Influence of subduction history on South American topography

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…

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…
