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 ...

Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...

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 ...

The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated ...

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active ...
