Category-based fractal modelling: A novel model to integrate the geology into the data for more effective processing and interpretation

Category-based fractal modelling: A novel model to integrate the geology into the data for more effective processing and interpretation Dr. Behnam Sadeghi and his PhD supervisor, Prof. David Cohen, has published another paper in Journal of Geochemical Exploration. This paper is based on his PhD thesis. In this research, they have proposed two novel fractal … Read more…

Chatting about reconstructing 1 billion years of Earth evolution in Geology Bites podcast

In the latest Geology Bites podcast series, Dietmar Muller talks about the challenges and benefits of reconstructing Earth evolution over a billion years with Oliver Strimpel, former astrophysicist and museum director, and Visiting Professor at the Department of Earth Sciences at Oxford University.  https://www.geologybites.com/ A transcript of the podcast can be found here.

Modelling global precipitation since 250 million years ago

We have developed a novel data-driven approach to reconstruct precipitation patterns through geological time, since the supercontinent Pangea was in existence. Our approach involves linking climate-sensitive sedimentary deposits such as coal, evaporites and glacial deposits to a global plate model, reconstructed paleo-elevation maps and high-resolution General Circulation Models via Bayesian machine learning. We model the … Read more…

Nicolas Flament awarded the AAS Anton Hales medal

Dr Nicolas Flament, University of Wollongong Dr Flament works at the interface between geodynamics and geology by novel 4D mathematical modelling of flow deep in Earth’s interior. He makes significant contributions to understanding our planet by connecting the evolution of the deep Earth with the evolution of its surface. He shows Earth was largely a water … Read more…

A geological postcard from Australia to Mars on NASA Perseverance

How a bit of the Australian desert is destined for the Red Planet – A small piece of the Pilbara holds the secret to an ancient geological environment that was common to Earth and Mars 3.5 billion years ago. Find out how Patrice Rey from the School of Geosciences played a pivotal role in unearthing … Read more…

Earth-moving research charts one billion years of tectonic plate movement

New research shows how the earth’s tectonic plates have shifted over the last billion years. Tectonic plates are irregular-shaped slabs of solid rock which can vary massively in size from a few hundred to thousands of kilometres across. Heat from radioactive processes within the planet’s interior causes the plates to shift. And this movement creates … Read more…
