12 Αυγ 2024 · Made of mostly solid rock, the mantle is typically inaccessible, as it sits between the crust and core. But at some places deep in the oceans, the parting of tectonic plates causes the mantle...
6 Μαΐ 2019 · This is the Kola Superdeep Borehole, the deepest manmade hole on Earth and deepest artificial point on Earth. The 40,230ft-deep (12.2km) construction is so deep that locals swear you can...
The Kola Superdeep Borehole SG-3 (Russian: Кольская сверхглубокая скважина СГ-3, romanized: Kol'skaya sverkhglubokaya skvazhina SG-3) is the deepest human-made hole on Earth (since 1979), which attained maximum true vertical depth of 12,262 metres (40,230 ft; 7.619 mi) in 1989. [1]
At certain places, tectonic activity churns mantle material into the crust, from whence we can take it. But drilling a deep hole at the bottom of the ocean at a tectonic boundary heated by volcanism, as you might imagine, is far easier said than done.
one deep hole has been drilled into ocean crust in the latest phase of operations (Hole U1473A drilled to ~790 m below seafloor at Atlantis Bank on the Southwest Indian Ridge in 2015–2016).
8 Αυγ 2024 · WASHINGTON, Aug 8 (Reuters) - 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...
8 Αυγ 2024 · A record-breaking expedition to drill into rocks at the bottom of the Atlantic Ocean has given scientists their best glimpse yet of what the Earth might look like underneath its crust.
