Latest Crust Stories
Two meteorites found in Antarctica are from an asteroid with an outer layer or crust similar to the Earth's continents, U.S.
Two rare meteorites found in Antarctica two years ago are from a previously unknown, ancient asteroid with an outer layer or crust similar in composition to the crust of Earth's continents
Two giant plumes of hot rock deep within the earth are linked to the plate motions that shape the continents, researchers have found.
A U.S.-led international team of scientists says it has, for the first time, recorded a geological event that is considered key in shaping the Earth's crust. Led by Purdue University Professor Eric Calais, the researchers said they measured ground displacements as two African tectonic plates moved apart and molten rock pushed its way toward the surface during the first so-called dyking event ever recorded within the planet's continental crust.
A new picture of the early Earth is emerging, including the surprising finding that plate tectonics may have started more than 4 billion years ago â€” much earlier than scientists had believed, according to new research by UCLA geochemists reported Nov. 27 in the journal Nature.
A new technique using X-rays has enabled scientists to play 'detective' and solve the debate about the origins of a three billion year old rock fragment.
A strip of bedrock located in the eastern area of Canada's Hudson Bay was discovered to have the oldest rocks on Earth, said scientists on Thursday. The rocks were formed about 4.28 billion years ago, shortly after the planet was created. It might even contain evidence of movement by ancient creatures.
Scientists at the University of Liverpool have developed a new exploration method to assist the oil and gas industry in identifying more precisely where the oceans and continents meet.
Diamonds from Brazil have provided the answers to a question that Earth scientists have been trying to understand for many years: how is oceanic crust that has been subducted deep into the Earth recycled back into volcanic rocks?
By Steinhoefel, Grit Hegner, Ernst; Oliver, Grahame J H Abstract: Major- and trace-element data and Nd isotope compositions for granitoid samples from the Grampian Highlands in Scotland show a systematic evolution in the composition of their sources in the course of the Caledonian Orogeny.
Earth -- in geology and astronomy, fifth largest planet of the solar system and the only planet definitely known to support life. Gravitational forces have molded the earth, like all celestial bodies, into a spherical shape. However, the earth is not an exact sphere, being slightly flattened at the poles and bulging at the equator. The equatorial diameter is c.7,926 mi (12,760 km) and the polar diameter 7,900 mi (12,720 km); the circumference at the equator is c.24,830 mi (40,000 km)....
