The evolution of the North West Shelf  »

1pm 5 November 2020

Understanding the mechanism driving the complex evolution of the North West Shelf of Australia is particularly complex which has experienced a series of Palaeozoic and Mesozoic rift events, many of which are associated with the separation of micro-continental fragments.

The European Alps and Plate Tectonics : A rocky relationship »

1pm 15 October 2020

Although the Alps are typically used as a “fossil” convergent margin akin to modern oceanic subduction zones, we will explore the geological record which suggests instead that the Alps might be better understood in terms of continental tectonics, namely extreme intracontinental extension, ultra-slow plate separation and compression of hyper-extended continental domains and we will discuss possible consequences.
