Sampling of the active alpine fault in New Zealand reveals extreme hydrothermal conditions
Aug 31, 2017 (SPX)
To investigate fault strength and heat generation in the Alpine Fault, the Deep Fault Drilling Project (DFDP) was commissioned. "The primary motivation of the D...
Data mining finds more than expected beneath Andean Plateau
Aug 28, 2017 (SPX)
"When crust from an oceanic tectonic plate plunges beneath a continental tectonic plate, as it does beneath the Andean Plateau, it brings water with it and part...
Ancient Earth's hot interior created 'graveyard' of continental slabs
Aug 23, 2017 (SPX)
For the most part, today's subducting slabs can only sink so far, to about 670 kilometers below the surface, before the mantle's makeup turns from a honey-like ...
How continents were recycled
Aug 23, 2017 (SPX)
Priyadarshi Chowdhury and Prof Dr Sumit Chakraborty from Ruhr-Universitat Bochum, together with Prof Dr Taras Gerya from the Swiss Federal Institute of Technolo...
Russian scientists have analyzed the process of rock destruction
Aug 23, 2017 (SPX)
The scientists have established that the stages of the deformation process are essentially different in the character of defect accumulation inside rocks. Dmitr...
Hot spot at Hawaii? Not so fast
Aug 21, 2017 (SPX)
Hot spots are areas where magma pushes up from deep Earth to form volcanoes. New results from geophysicist Richard Gordon and his team confirm that groups of ho...
World's largest volcanic range may lurk beneath Antarctic ice
Aug 16, 2017 (SPX)
Researchers from the University of Edinburgh remotely surveyed the underside of the ice sheet for hidden peaks of basalt rock, like those of other volcanoes in ...
New plate adds plot twist to ancient tectonic tale
Aug 16, 2017 (SPX)
The Malpelo Plate, named for an island and an underwater ridge it contains, is the 57th plate to be discovered and the first in nearly a decade, they said. They...
Scientists discover new tectonic plate
Aug 14, 2017 (UPI)
Scientists discovered the microplate -- which they've dubbed "Malpelo" -- while analyzing the movements of what they believed to be the convergence of a trio of...
ASU geoscientists find explanation for puzzling pockets of rock deep in Earth's mantle
Aug 03, 2017 (SPX)
These pockets, lying roughly 2,900 kilometers (1,800 miles) below the surface, have been known for many years, but previously lacked an explanation of how they ...
Conductivity measurements to help scientists map water in Earth's mantle
Jul 26, 2017 (UPI)
Earth is the only planet in the solar system to develop plate tectonics and large liquid water oceans on its surface. Planetary scientists believe the distribut...
Strength of tectonic plates may explain shape of the Tibetan Plateau
Jul 25, 2017 (SPX)
The new findings are published in the journal Nature Communications. Even from space, the Tibetan Plateau appears huge. The massive highland, formed by the conv...
Scientists shed light on carbon's descent into the deep Earth
Jul 21, 2017 (SPX)
This study, published in Nature Communications, offers an explanation of carbon's descent into the deep Earth. "The stability regions of carbonates are key to u...
The mysterious bend in the Hawaiian-Emperor chain
Jun 14, 2017 (SPX)
The cause for this bend has been heavily debated for decades. One explanation is an abrupt change in the motion of the Pacific tectonic plate, the opposite mode...
Neutrons zero in on the elusive magnetic Majorana fermion
Jun 12, 2017 (SPX)
A research team led by the Department of Energy's Oak Ridge National Laboratory has confirmed magnetic signatures likely related to Majorana fermions - elusive ...
ASU-led scientists discover why rocks flow slowly in Earth's middle mantle
Jun 07, 2017 (SPX)
Shim and his research team combined X-ray techniques in the synchrotron radiation facility at the U.S. Department of Energy's National Labs and atomic resolutio...
The birth and death of a tectonic plate
May 25, 2017 (SPX)
In fact, this region represents the single greatest geophysical hazard to the continental United States; quakes centered here could register as hundreds of time...
What goes down, must come up: Stirring things up in the Earth's mantle
May 15, 2017 (SPX)
The new findings suggest that the mantle does not flow ubiquitously, as has been previously thought - and that it is instead divided into two very large domains...
Deep-seated tectonic genesis of large earthquakes in North China
May 10, 2017 (SPX)
In the past 50 years, Chinese seismologists have carried on the large-scale deep geophysical exploration and research, obtained the detailed crustal and upper m...
New theory on how Earth's crust was created
May 09, 2017 (SPX)
Conventional theory holds that all of the early Earth's crustal ingredients were formed by volcanic activity. Now, however, McGill University earth scientists D...
