Papers presented in a special symposium at the joint annual meeting of the Geological and Mineralogical Associations of Canada at St. John's in May, 1974. Tectonic settings for emplacement of ...

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 ...

Computational modeling shows that plate tectonics weren't necessary for early continents. The formation of Earth's continents billions of years ago set the stage for life to thrive. But scientists ...

Using information from inside the rocks on Earth’s surface, my colleagues and I have reconstructed the plate tectonics of the planet over the last 1.8 billion years. It is the first time Earth’s ...

For millions of years, Earth’s moving plates have sculpted continents, carved oceans, and built massive mountain ranges. Yet some of these giant structures vanished deep into the mantle, hidden from ...

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, ...

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 ...

Far beneath the ocean's surface, where mountain belts rise and ancient oceanic crust lies hidden, a long-lost tectonic plate has been brought back into view. In one of Earth's most tectonically ...

New research has allowed geoscientists to show the uninterrupted movement of Earth's tectonic plates over the past billion years. Geoscientists have released a video that for the first time shows the ...
