Dec. 7, 2020 —A team of researchers understands more about the melting of the Greenland ice sheet. They discovered a flow of hot rocks, known as a mantle plume, rising from the core-mantle boundary beneath central ...
Jan. 7, 2021 —黄石热区generati是众所周知的ng supereruptions in the geologic past that are far more explosive than historic examples. The origin and sustained longevity of the hotspot is less ...
July 11, 2022 —By analyzing noble gas isotope data, a scientist determined that the ancient plume mantle (the deep part) had a water concentration that was a factor of 4 to 250 times lower when compared with the ...
Nov. 22, 2021 —Volcanic gases are helping researchers track large-scale movements in Earth's deep interior. Scientists have discovered anomalous geochemical compositions beneath ...
Feb. 17, 2021 —Geologists have developed a new theory about the state of Earth billions of years ago after examining the very old rocks formed in the Earth's mantle below the ...
Jan. 14, 2022 —Researchers have demonstrated in the lab how well a mineral common at the boundary between the Earth's core and mantle conducts heat. This leads them to suspect that the Earth's heat may ...
Aug. 30, 2022 —Scientists discover that a potential 'diamond factory' may have existed at Earth's core-mantle boundary for billions of ...
Feb. 6, 2023 —Scientists have discovered a new layer of partly molten rock under the Earth's crust that might help settle a long-standing debate about how tectonic plates move. The molten layer is located ...
Sep. 26, 2022 —The transition zone between the Earth's upper and lower mantle contains considerable quantities of water, according to an international study. The research team analyzed a rare diamond formed ...
Dec. 22, 2020 —Scientists present important new constraints showing that plate tectonics started relatively slow, although the early Earth's interior was much hotter than ...
