Scientists use tiny minerals called zircons as geologic timekeepers. Often no bigger than a grain of sand, these crystals record chemical signatures of the geological environment where they formed. In ...

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 ...

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 ...

A giant fan-shaped network of hidden basins has been discovered beneath East Antarctica, revealing that several well-known subglacial features are actually part of one massive geological structure.

Nov. 5 (UPI) --New satellite surveys and fresh gravity datasets are helping scientists image tectonic structures, revealing links between Antarctica and the rest of Earth's continents. Using data ...

It’s right there in the name: “plate tectonics.” Geology’s organizing theory hinges on plates—thin, interlocking pieces of Earth’s rocky skin. Plates’ movements explain earthquakes, volcanoes, ...

Researchers describe zircons from the Andes mountains of Patagonia. Although the zircons formed when tectonic plates were colliding, they have a chemical signature associated with when the plates were ...
