We cautiously conclude that deep mantle materials might have been involved during the formation of the Songduo eclogites.doi:10.1007/s12583-019-1226-9Zhaoli LiKey Laboratory of Deep-Earth Dynamics of Ministry of Natural ResourcesJingsui Yang
Volcanism of the Abu group is believed to be caused by upwelling mantle diapirs, and is is related to subduction of the Philippine Sea Plate. The volcanic group is part of the southwestern Japanese arc, which lies subparallel to the Nankai trough. The erupted magmas of Abu are mainly ...
It is located at the junction between the eastern and northern volcanic rift zones in the area where the present-day center of the mantle hot spot beneath Iceland is thought to be. Bardarbunga has had about 300-400 eruptions during the past 10,000 years which includes only 23 eruptions ...
What makes the seismic surface waves so important to researchers is that they provide information about the structure of the Martian crust. Seismic body waves, which travel through the planet’s interior during a quake, have so far provided insights into Mars’s core and mantle, but have reveal...
Golden-mantled ground squirrels), small ground squirrels found in forested areas throughout the Western United States, can easily be confused with chipmunks. The top picture compares the Golden-mantled ground squirrel (in the front) with a striped faced chipmunk in the background. Chipmunks also...
[#insert3] Measurements of its gravity field tell us that the rock and metal sank to form a core about the size of our Moon, with a mantle and crust of ice floating above it. [#insert4] In addition, the Galileo spacecraft discovered that Ganymede has a magnetic field, the [#high...
6/2/2016 - A shocking discovery by scientists shows that the Earth's mantle is moving ten times faster than originally thought, as reported by the Daily Mail. The revelation, which has taken researchers by complete surprise, came after the first comprehensive survey of the Earth's mantle. ...
Mostdiamondsform under extreme pressure and at very high temperatures, typically at depths of over 140 kilometers inside Earth's mantle. On average,diamond formationoccurs over periods of 1 to 3.3 billion years, until they are surfaced through deep volcanic eruptions of a rare type of magma cal...
Heard Island is the top of an active stratovolcano on the Kerguelen Plateau in the southern Indian Ocean, about 4000 km southwest of Western Australia. Part of Australian territory, along with McDonald Island to the west, Heard is one of Australia's two currently active volcanoes. The volcano...
