Tectonic, geodynamic and surface process driving forces of Australia’s paleogeography since the Jurassic

Abstract: Today the eastern highlands of Australia are significantly more elevated than western Australia, but the continent’s geodynamic evolution suggests that the opposite was the case during Cretaceous times, when the Eromanga Sea dominated the eastern Australian landscape. Previous geodynamic and surface processes models have been used to simulate the evolution of this seaway, but … Read more…

Geodynamic reconstruction of an accreted Cretaceous back-arc basin in the Northern Andes

Abstract A complex history of subduction, back-arc basin formation, terrane accretion and transpressional shearing characterizes the evolution of the Caribbean and northern South American margin since Jurassic times. Quantitative plate tectonic reconstructions of the area do not include Jurassic-Cretaceous back-arc terranes of which there are both geological and geophysical observations. We developed a revised plate … Read more…

Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…

EarthByte helps the International Science School

Nikita and Jono at the International Science SchoolEarthByte helped run the 2015 geosciences workshop for the University of Sydney’s International Science School, with over 140 high school students engaging in activities from a wide range of research topics and teaching areas at the School of Geosciences. Thanks to all the brilliant EarthByte volunteers, including Mandi Thran, Nikita Golkin, Luke Hardiman, Jono Leonard and Carmen Braz.
