PyBacktrack 1.1 has been released as Python package and Docker image

PyBacktrack is a Python package that backtracks the paleo-water depth of ocean drill sites through time by combining a model of tectonic subsidence with decompaction of the site stratigraphic lithologies. PyBacktrack can also include the effects of mantle-convection driven dynamic topography on paleo-water depth, as well as sea-level variations. PyBacktrack provides a model of tectonic … Read more…

How Earth’s continents became twisted and contorted over millions of years

Dietmar Muller, Maria Seton and Sabin Zahirovic published an article in The Conversation on How Earth’s continents became twisted and contorted over millions of years based on their recently published paper in Tectonics. Classical plate tectonic theory was developed in the 1960s. It proposed that the outer layer of our planet is made up of a small number of rigid … Read more…

The interplay of dynamic topography and eustasy on continental flooding in the late Paleozoic

Abstract: Global sea level change can be inferred from sequence stratigraphic and continental flooding data. These methods reconstruct sea level from peri-cratonic and cratonic basins that are assumed to be tectonically stable and sometimes called reference districts, and from spatio-temporal correlations across basins. However, it has been understood that long-wavelength (typically hundreds of km) and … Read more…

AuScope reviews innovations of the ARC Basin Genesis HUB

Sedimentary basins around the world are critical to sustaining modern life on Earth. These basins can be thought of as containers that hold water, minerals, energy, and can potentially be used to store carbon dioxide. Unpacking how they form, and where those resources and storage opportunities may lie is a sizeable feat for the best … Read more…

GPlates-in-schools!

Atlas Obscura: Marine Snow Has Cooled the Planet with Dead Plankton for Millions of Years

The bodies of the tiny organisms lock away enormous amounts of carbon dioxide, and they’re in danger. The bottom of the Ocean holds one of the world’s largest and most populous graveyards. It’s crammed with organisms too tiny to see, including plankton, protists, and a type of marine algae called coccoliths. The continuous shower of bodies … Read more…

How marine snow cools the planet

University of Sydney scientists have modelled how carbonate accumulation from ‘marine snow’ in oceans has absorbed carbon dioxide over millennia and been a key driver in keeping the planet cool for millions of years. Researchers in the School of Geosciences have mapped out how carbonate formations have helped regulate Earth’s temperature over 120 million years. … Read more…
