Decoding earth’s plate tectonic history using sparse geochemical data

Abstract: Accurately mapping plate boundary types and locations through time is essential for understanding the evolution of the plate-mantle system and the exchange of material between the solid Earth and surface environments. However, the complexity of the Earth system and the cryptic nature of the geological record make it difficult to discriminate tectonic environments through … Read more…

GPlates 2.2 software and data sets

GPlates Title Logo

GPlates 1.5 PromoGPlates is a free desktop software for the interactive visualisation of plate-tectonics. The compilation and documentation of GPlates 2.2 data was primarily funded by AuScope National Collaborative Research Infrastructure (NCRIS).

GPlates is developed by an international team of scientists and professional software developers at the EarthByte Project (part of AuScope) at the University of Sydney, the Division of Geological and Planetary Sciences (GPS) at CalTech, the Geodynamics team at the Geological Survey of Norway (NGU) and the Centre for Earth Evolution and Dynamics (CEED) at the University of Oslo. … 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…
