A section of the mantle of land under Oman is seen less warmly, as researchers may have been the first “Ghost Pluming with no obvious volcanic activity above.
The mantle plumes are mysterious upwings of molten stone believed to send heat from the border of the core of the land surface, away from the edges of tectonic plates. There are a dozen or as examples considered to occur under the middle of the continental plates – for example, under the Yellowstone and the East Africa Rift. “But all these cases where there is a volcano on top,” says Simone Pidia In the King Fahd University of Petroleum and Minerals in Saudi Arabia. Oman has no such volcanic clues.
Choose first came to the suspect there was a plumes under Oman “serbizing” after he began to analyze the new seismic data from the region. He monitors the speed of the waves made with distant earthquakes slowly in a cylindrical area under eastern Oman, which indicates rocks less strong than high temperatures.
Other independent measurements of seismic appeared key boundaries where the minerals deep in the soil changes the stages of a hot plume. These measurements suggest that the plume lasts more than 660 kilometers under the surface.
The presence of a plume can also explain why the region continues to increase the high-time tectonic compression – a geological process in which the ground crust is crusted. It also suits the models of what causes the transfer of moving on Indian tectonic plate.
“If we have a lot of evidence, we are more convinced that it is a plume,” says Select, leading the geologic part of the “Dani Plume” next to his son.
“It can” have a plume when there, as Saskia goes In imperial College London, the addition of study is “full”. However, he pointed the narrow plumes harder to find out.
If there is, however, the presence of a “space used in the robe of the relatively thick stone layer under Oman suggests that there is something else,” we are convinced. “
If there are many other secret plumes, it may mean more heat from the core that directly runs mantle by mantle through the mantle by the more slowly encounter, saying to go. “It has implications, potential, for evolution of land when we get a different estimate of how much heat from the mantle.”
