Survey reveals mineral rich fault lines
The Geological Survey of Western Australia has confirmed that the remains of a small continent, about the size of Japan, is embedded in central Western Australia.
Understanding the forces that shape the Earth
Subduction is the process occurring where the Earth's tectonic plates meet - and one plate slides beneath the other, taking surface material to its interior. This process leads to a large variety of phenomena ...
New model of Earth's interior reveals clues to hotspot volcanoes
Scientists at the University of California, Berkeley, have detected previously unknown channels of slow-moving seismic waves in Earth's upper mantle, a discovery that helps explain "hotspot volcanoes" that ...
Out of Africa? New bamboo genera, mountain gorillas, and the origins of China's bamboos
African mountain bamboos are something of a mystery, as nearly all bamboos are found in Asia or South America. Hidden away up mountains in the tropics where they provide food for gorillas, just as China's ...
Geoscientists discover hillslopes can reveal geographic activity below
Rising mountains, cooling oceans prompted spread of invasive species 450 million years ago
New Ohio University research suggests that the rise of an early phase of the Appalachian Mountains and cooling oceans allowed invasive species to upset the North American ecosystem 450 million years ago.
Africa's ups and downs
The East African Rift is an area where two tectonic plates are moving apart, making it a region of high geological activity, home to a number of volcanoes.
Newly discovered flux in the Earth may solve missing-mantle mystery
It's widely thought that the Earth arose from violent origins: Some 4.5 billion years ago, a maelstrom of gas and dust circled in a massive disc around the Sun, gathering in rocky clumps to form asteroids. ...
The case for alien life
Only one planet has been proven to support life: Earth. But evidence is mounting that we are not alone. Biogeochemist Ariel Anbar and astrophysicist Steven Desch, professors in ASU's School of Earth and Space ...
Melting in the Afar helps scientists understand how oceans form
Lavas from the Afar Depression in Ethiopia, where three tectonic plates are spreading apart, have given scientists a new insight into how ocean basins form.
Earth from Space: Peruvian landscape
The foothills of the Andes mountains near the southern coast of Peru are captured by the Kompsat-2 satellite.
Study reveals ancient jigsaw puzzle of past supercontinent
A new study published today in the journal Gondwana Research, has revealed the past position of the Australian, Antarctic and Indian tectonic plates, demonstrating how they formed the supercontinent Gondwa ...
Location of upwelling in Earth's mantle discovered to be stable
A study published in Nature today shares the discovery that large-scale upwelling within Earth's mantle mostly occurs in only two places: beneath Africa and the Central Pacific. More importantly, Clinton Conrad ...
New 'embryonic' subduction zone found
(Phys.org) —A new subduction zone forming off the coast of Portugal heralds the beginning of a cycle that will see the Atlantic Ocean close as continental Europe moves closer to America.
