29 Αυγ 2023 · Mantle plumes originate at depths near the core−mantle boundary (~2,800 km). As such, they provide invaluable information about the composition of the deep mantle and insight into...
12 Αυγ 2024 · When seawater reacts with mantle rocks beneath the Earth’s surface, it can produce hydrogen and methane, which bubble back into the ocean through hydrothermal vents.
15 Αυγ 2024 · A recent 1268-meter drill core into Earth’s mantle from the Mid-Atlantic Ridge has revealed new insights into its mineral composition and processes, challenging existing geological models and underscoring the role of deep-sea drilling in scientific discovery.
8 Αυγ 2024 · Examining the composition and dynamics of Earth’s upper mantle—the largest layer of Earth’s interior—can reveal its biogeochemical effects on the marine system. However, it is situated 6 to 70 km below Earth’s surface and is challenging to study.
8 Αυγ 2024 · Scientists using an ocean drilling vessel have dug the deepest hole ever in rock from Earth's mantle - penetrating 4,160 feet (1,268 meters) below the Atlantic seabed - and obtained a large...
8 Αυγ 2024 · In the middle of the North Atlantic Ocean, geologists have burrowed 1268 metres below the seafloor – the deepest hole drilled into Earth’s mantle yet.
Earth's mantle, to we surface-crawlers, is frustratingly out of reach. At its thinnest, Earth's crust is 6 kilometers (3.7 miles) thick. We do have the tools to drill down pretty deep from the continental surface – as evidenced by the mind-blowing 12,262-metre deep Kola borehole in Russia – but the continental crust is a lot thicker than ...
