The Neogene evolution of the Murray Basin – a unique continental archive of tectonic, climatic and geomorphic change

Over the last 40 million years large volumes of sedimentary rock were deposited in a remarkable intracontinental depocentre that extended across south-eastern Australia. This region, known as the Murray Basin, was developed above regions of eastern Australia that have a pre-history going back into the Cambrian. This talk will look at the different sedimentary rocks within the Murray Basin and the broader tectonic environment in which this basin developed. These observations provide insight on the climatic, environmental and geomorphic evolution, including regional-scale tectonics, drainage reorganisation and the onset of now-characteristic arid climatic conditions.
