Geologists found an ancient seafloor trapped deep beneath Earth's mantle, which could solve many previous puzzling observations.
A long-debated missing tectonic plate beneath Northern Canada has been confirmed with 3D mapping technology.
Geologists have now found the most compelling evidence of granites on Mars – something which prompts more complex theories about the geology and tectonic activity on the Red Planet. Granites and basalts Granites are igneous rocks, pretty common on the surface of Earth. It is often called a ‘felsic’ (white rock) – because it is […]
For decades, the accepted theory was that the mountain chains running from Alaska to Mexico were created from fragments of land scraped off a huge tectonic plate moving eastwards, called the Farallon, that converged with North America and sunk below it over the past 200 million years or so. But alas, geologists and geophysicists aren’t […]
Millions of years ago, an ancient tectonic plate called the Farallon oceanic plate used to sit between the Pacific and North American plates. In time, the plate “disappeared” beneath the North American one, however geologists at Brown University have now found physical surface remnants of the plate under sections of central California and Mexico. The Farallon surface […]
An 8.6-magnitude earthquake and powerful aftershocks struck the coast of Indonesia today, resurrecting fears of a big tsunami like the one responsible for one of the biggest modern disasters ever. However, this earthquake, which struck at 2:38 p.m. local time (4:38 a.m. ET), about 270 miles (435 kilometers) off the coast of the Indonesian island […]
Scientists who observed an underwater eruption in 2009 concluded they observed a tear in the planetary crust that mimicks the birth of a subduction zone. Subduction takes place at convergent tectonic plate boundaries; basically, one plate slides below the other – an extremely complicated and complex process that drives along a series of other processes, […]
