The modern Seattle fault zone cuts directly through the densely populated Puget lowlands, including Seattle and its metro area. Fifty million years ago, the continent tore in two here, setting the geologic stage for the modern faults, according to a new Tectonics study. Credit: Washington Geological Survey.

Three types of granitoid rocks—tonalite, trondhjemite and granodiorite (TTG).

Researchers uncover source rocks of the first real continents

Shears — or breaks caused by strain — in rock outcrops like the one pictured here could shed new light on tectonics that occur between major earthquakes in the subduction zone, according to new research.

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, and the non-depletion of melt-mobile incompatible trace elements in the mantle.
