Plate tectonics from a perspective of continental crustal growth
An illustration of what we know about plate tectonics on Earth by Hee Choi.

Understanding the plate tectonics initiation can give us incredible opportunity to guess the physical state of the early Earth. This week, Hee Choi, a Ph.D. candidate, takes us on a journey on initiation of plate tectonics and how continental crustal growth is related to it. Our planet Earth is the only place where plate tectonics takes place. No other planet or rocky moon in our solar system has ...[Read More]

Can plume-lithosphere interaction initiate a modern subduction zone?

Plume-induced subduction inititation?

This week in News & Views, dr. Marzieh Baes from GFZ Potsdam introduces us to the mechanisms behind subduction initiation. Moreover, she discusses the different types of subduction initiation in reaction to plume-lithosphere interaction that she observed in her recent 3-d numerical modelling study. Possible scenarios of subduction initiation According to plate tectonics, oceanic plates are for ...[Read More]

Subduction zones are ubiquitous features on Earth, and an integral part of plate tectonics. They are known to have a very important role in modulating climate on Earth, and are believed to have played an essential part in making the Earth’s surface habitable, a role that extends to present-day. This week, Antoniette Greta Grima writes about the ongoing debate on how subduction zones form and persi ...[Read More]
