Geophysics Seeking The Truth Hidden In The Earth’s Lowermost Mantle If we were lucky to travel to the Earth’s centre, perhaps as part of an international crew of terranauts chosen to observe and investigate our planet’s interior…
Geodynamics High mantle seismic P-wave-speeds as a signature for pancake-like flow in the upper mantle Buoyant material rising in the Earth's mantle is expected to spread out when it reaches the base of a tectonic plate like pancake batter dropped into a pan.
Geodynamics A tight squeeze between tectonic plates The largest earthquakes occur at subduction zones, where one plate descends beneath another into the underlying mantle, at a convergent plate boundary. Some subduction zones seem to host more large
Seismology The inherited structures within the Australian lithosphere define the tectonic evolution along the Banda arc Integration of passive seismic images, geochemistry, and reconstruction of uplift from river profiles provide new findings on arc-continent collisional processes
Geodynamics The Earth's troubled childhood Continents host the oldest building blocks of the Earth's surface and keep a record of the processes that shaped it. A careful reading and high-performance computational modelling of the early, hotter Earth reveal a coming of age story.
Publications Unusual geochemical signature in Arctic ocean floor basalts Earth’s tectonic plates are constantly moving. Over millions of years new plates form at oceanic ridges, while others form mountains or even sink back in the mantle and disappear from the surface. The unique geochemical signature of sunken plates can be preserved and reappear in newly formed crust.
Geodynamics How is 'social distancing' maintained between strike-slip faults? Haibin Yang, Louis Moresi and Mark Quigley provide a scaling relationship for the fault spacing in continental strike-slip shear zones.
Geophysics Tweed Valley a ‘natural laboratory’ to model impacts of climate change and test carbon sequestration theory Kyle Manley, Tristan Salles Dietmar Müller Since roughly 1880 the Earth has warmed by 1 deg C, many times faster than any warming episode in the past 65 million years
Publications From Antarctica to Australia: Mighty River’s Story Revealed A group of researchers have traced a mighty Gondwana river back to its distant source - in the mountains of East Antarctica. They’ve been able to show that this colossal river flowed for over 200 million years, making it a candidate for one of the top ten longest-lived rivers in Earth’s history.
Geophysics The secret to starting subduction is ... subduction A new study by an international team of researchers offers new clues about where and how subduction starts on Earth, the process behind our most deadly volcanic eruptions.

Publications Craton Formation and the Onset of Plate Tectonics Cratons are anomalously-strong regions of the continents that have largely resisted tectonic forces for billions of years. How such strong…
