Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely ...
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 ...
How long ago did plate tectonics – the slow movement of great land plates in Earth’s outer shell – begin? We don’t know for certain. But estimates range from 4 billion years ago to as recently as 800 ...
The emergence of plate tectonics in the late 1960s led to a paradigm shift from fixism to mobilism of global tectonics, providing a unifying context for the previously disparate disciplines of Earth ...

How the tectonic plates were formed
Earth’s crust looks solid from the surface, but it is broken into a shifting mosaic of slabs that slowly rearrange oceans and continents. Understanding how those tectonic plates first formed is one of ...
The plate tectonics theory established in the 20th century has been successful in interpreting many geological phenomena, processes, and events that have occurred in the Phanerozoic. However, the ...
Using information from inside the rocks on Earth’s surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s geological record has ...
