A hidden shard of ancient crust has been detected where California’s San Andreas system collides with the Cascadia subduction zone, reshaping how I understand the tectonic engine of the West Coast.

A tectonic plate that disappeared under North America millions of years ago still peeks out in central California and Mexico, new research finds. The Farallon oceanic plate was once nestled between ...

Ancient plate tectonics in the Archean period differs from modern plate tectonics in the Phanerozoic period because of the higher mantle temperatures inside the early Earth, the thicker basaltic crust ...

New finding contradicts previous assumptions about the role of mobile plate tectonics in the development of life on Earth. Moreover, the data suggests that 'when we're looking for exoplanets that ...

Structural geology is the discipline devoted to the study of rock deformation and the resulting features – such as folds, faults, joints and other discontinuities – that record the history of tectonic ...

The Tiombó conglomerate on Isla del Carmen in Baja California Sur represents a mega-delta deposited mainly during the middle Pliocene (early Piacenzian age). A cross-section with the ...

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 ...

Some great ideas shake up the world. For centuries, the outermost layer of Earth was thought to be static, rigid, locked in place. But the theory of plate tectonics has rocked this picture of the ...
