Plate tectonics may be unique to Earth and may be an essential characteristic of habitable planets. Estimates for its onset range from over 4 billion years ago to just 800 million years ago. A new ...

This study is led by Prof. Yong-Fei Zheng at University of Science and Technology of China. It focuses on the development of tectonic processes along convergent plate margins through inspection of ...

How is plate subduction factory operated during continental collision? How do physical mixing and chemical reaction proceed at colliding continental margins of different depths? How is continental ...

Earth's geographical surfaces have been formed over millions of years, and various current theories aim to explain their formation. The most popular theory, called the "plate tectonics theory," states ...

A handful of ancient zircon crystals found in South Africa hold the oldest evidence of subduction, a key element of plate tectonics, according to a new study published in the open access journal AGU ...
