Geology: The role of surface processes in basin inversion and breakup unconformity

In the context of continental extension, transient compressional episodes (stress inversion) and phases of uplift (depth inversion) are commonly recorded with no corresponding change in plate motion. Changes in gravitational potential energy during the rifting process have been invoked as a possible source of compressional stresses, but their magnitude, timing, and relationship with depth inversions … Read more…

The role of asthenospheric flow during rift propagation and breakup

Abstract Continental rifting precedes the breakup of continents, leading to the formation of passive margins and oceanic lithosphere. Although rifting dynamics is classically described in terms of either active rifting caused by active mantle upwelling, or passive rifting caused by far-field extensional stresses, it was proposed that a transition from passive to active rifting can … Read more…

Basin GENESIS Hub opening group photo 19 August 2015

Basin GENESIS Hub opening group photo 19 August 2015The ARC Research Hub for Basin Geodynamics and Evolution of Sedimentary Systems (Basin GENESIS Hub) opened today at a reception held in the Charles Perkins Centre at the University of Sydney. The launch as attended by representatives from Universities, industry, Geoscience Australia, the ARC, the NCI and the Office of the NSW Chief Scientist and Engineer.

The Basin GENESIS Hub will use computer modelling to fine-tune our understanding of the nation’s sedimentary basins, which hold many of the natural resources we use in day-to-day life.

The research will be of fundamental importance to the geo-software industry used by exploration and mining companies, explains Hub Director Professor Dietmar Müller from the University of Sydney.  … Read more…


Continental rifting in 3D using Underworld

This model shows the evolution of a continental rift from inception to breakup, using the Underworld numerical modelling framework. The left and right walls of the model are pulled apart from each other at a total rate of 2 cm/yr to induce rifting.Courtesy of Luke Mondy, EarthByte.View other EarthByte animations on our YouTube channel
