The strains of a continental breakup

Every now and then in Earth's history, a pair of continents draws close enough to form one. There comes a time, however, when they...

Plate tectonics without jerking

The earthquake distribution on ultraslow mid-ocean ridges differs fundamentally from other spreading zones. Water circulating at a depth of up to 15 kilometres leads...

Why do intracontinental basins subside longer?

Intracontinental basins like the North German Basin, the West Siberian Basin, the Barents Sea or the Congo Basin are large depressions of the Earth’s...

Oxygen atmosphere recipe = tectonics + continents + life

Earth scientists from Rice University, Yale University and the University of Tokyo are offering a new answer to the long-standing question of how our...

Continental drift created biologically diverse coral reefs

Nowhere today is the biodiversity of corals and reef-inhabiting fish higher than in the tropical waters around Indonesia and its neighbouring countries in Southeast...

Supercontinent rift formed bizarre Bunbury rocks

Bunbury beachgoers may be unsettled to learn that the refreshing, blue stretch of water off the port city was preceded by a huge lava...

Researchers define links within two supercontinents

A University of Wyoming researcher contributed to a paper that has apparently solved an age-old riddle of how constituent continents were arranged in two...

Ancient rocks of Tetons formed by continental collisions

University of Wyoming scientists have found evidence of continental collisions in Wyoming's Teton Range, similar to those in the Himalayas, dating to as early...

Breakthrough in continuous monitoring of CO2 leaks from storage sites could...

Fukuoka, Japan - Carbon capture and storage projects rely on effective monitoring of injected CO2. However, the high number of necessary surveys makes this...

New gravity dataset will help unveil the Antarctic continent

A unique dataset of gravity anomalies has been released for Antarctica representing a significant step forward in the investigation of the largest ice-covered continent...

Scientists detect deep carbon emissions associated with continental rifting

Scientists at the University of New Mexico conducted research to effectively study carbon emissions through fault systems in the East African Rift (EAR) in...

Chinese continental shelf of exotic origin collided with continental China 100...

It has been axiomatically accepted that the basement of a continental shelf is the offshore extension and geologically part of the same continental lithosphere....

How do continents break up?

When the western part of the super-continent Gondwana broke up around 130 Million years ago, today's Africa and South-America started to separate and the...

Fragment of continental crust found under south east Iceland

An international team, including researchers at the University of Liverpool, have shown that south east Iceland is underlain by continental crust. The team found that...

Scientists discover elusive secret of how continents formed

An international research team, led by a Virginia Tech geoscientist, has revealed information about how continents were generated on Earth more than 2.5 billion...

Questions of continental crust

Geological processes shape the planet Earth and are in many ways essential to our planet's habitability for life. One important geological process is plate...

Mysterious Midcontinent Rift is a geological hybrid

An international team of geologists has a new explanation for how the Midwest's biggest geological feature -- an ancient and giant 2,000-mile-long underground crack...

Hottest lava eruption linked to growth of first continents

A collaborative research team has discovered an important link between the eruption of Earth's hottest lavas, the location of some of the largest ore...

Earth’s breathable atmosphere a result of continents taking control of the...

Scientists investigating one of the greatest riddles of Earth's past may have discovered a mechanism to help determine how oxygen levels in the atmosphere...

Asymmetric continental margins and the slow birth of an ocean

When South America split from Africa 150 to 120 million years ago, the South Atlantic formed and separated Brazil from Angola. The continental margins...
