The geodynamic processes behind the generation of the earliest continents

The geodynamic processes behind the generation of the earliest continents

The earliest continents played a fundamental role on Earth’s habitability. However, their generation is still not understood, and it requires an integrated approach between petrology and geodynamic modelling. In a new study, Piccolo and co-workers developed a method to handle the effects of chemical evolution on the geodynamic processes. They show that the production of the earliest felsic c ...[Read More]

Pre-plate-tectonics on early Earth: How to make primordial continental crust

Pre-plate-tectonics on early Earth: How to make primordial continental crust

The sequence of events before continental crust formation has long been contested. Numerical simulations performed by Rozel and colleagues imply that the key to the puzzle could lie in the intrusive magmatism. Despite several decades of research on the topic, the trigger of proto-continental crust formation on early Earth remains an enigma. However, magmatic processes may hold the key to unravelli ...[Read More]
