Unprecedented: Scientists drill into Earth's mantle and extract record-breaking amount of rock.

Scientists have drilled nearly a mile beneath the ocean floor at an underwater mountain in the middle of the Atlantic Ocean, reaching a "tectonic window" where the rocks of the Earth's mantle have been pushed close to the surface. This is a record-breaking achievement by the ocean drilling vessel JOIDES Resolution, although the scientists did not technically drill into the mantle, and the hole isn't the deepest ever drilled beneath the ocean floor.

"Geologists Retrieve Historic Samples of Earth's Mantle Through Deep-Sea Drilling"

Geologists aboard the JOIDES Resolution ship have drilled down to 1,000 meters below the sea floor to collect mantle rock samples from beneath the Lost City Hydrothermal Field. The samples are expected to provide new insights into the composition and structure of the mantle, as well as processes that take place within it. The team has already sampled mantle rock that has never melted into magma, but some geophysicists argue that the samples show signs of seawater influence and should be termed deep crust rather than mantle.

"Breakthrough: Scientists Extract Historic Mantle Samples Through Earth's Crust"

Geoscientists aboard the JOIDES Resolution drilling vessel have collected pieces of Earth's rocky mantle from a mile beneath the North Atlantic ocean floor at an underwater mountain called Atlantis Massif. Although they did not drill into the mantle, they did recover the deepest mantle rock ever, getting samples from as deep as 4,157 feet. The samples can provide direct evidence for how ocean crust differs in composition from the upper mantle, better estimates of “the global composition of the bulk Earth,” and help researchers better understand how magma melts, flows, and separates.
