Earth's scorching core is not a loner — it has been caught mingling with other, underworldly layers. That's according to a new study that found the innermost part of the planet leaks some of its contents into mantle plumes, some of which eventually reach Earth's surface. This discovery ...
Ambient noise tomography strikes GG as something that might be considered worthy. At a minimum, it rescued EarthScope from promises made that could not otherwise have been kept. Slow-slip/tremor in subduction zones seems a worthy discovery as the community tries to see… ...
The wall mounted electrical boiler comprises a water heating tank connected to independent domestic hot water and central heating networks. It consists of a coil submerged in the tank for the direct heat exchange with the tank water which is then widened to form a reheat chamber with an immersed...
There is no "direct" proof of subduction. No experimental objects have been placed to measure it and no land masses have ever been oberved moving towards each other. [*] So the question arises: is there an alternate theory? And what does this theory reveal about "doomsday"?
Just found the current balance: 0.2 GtC/year deposit as carbonate, 0.03 GtC recycled via (subduction) volcanoes and 0.17 GtC/year recycled via rock weathering, thus practically in balance. During the Cretaceous, deposits were much higher and less rock exposed to weather, thus mor...
, it is the long chain that is the aleutians that come to mind. however, in eastern alaska there is a range of volcanic and tectonic mountains called the wrangell-st. elias range . isolated from the aleutians, they volcanoes might be related to the subduction of a small tectonic terrane...
Subduction, the term used for rocks from Earth's surface descending into the mantle, takes oxygen-rich material from the surface into the deep mantle as an integral component of plate tectonics. Experiments show that increase in oxygen concentration at the core-mantle boundary could causetungstento...
“Subduction, the plunging of one plate under the other, is the basic way in which mountain chains are formed,” said Van Hinsbergen. “Our research provided a large number of insights, also about volcanism and earthquakes, that we are already applying elsewhere. You can even predict, to a...
