Recovery of rocks that originated in Earth's mantle could reveal secrets of planet's history

The recovery of a long section of mantle rocks from the Mid-Atlantic Ridge, led by the International Ocean Discovery Program, is a major achievement that will enable studies of the mantle's role in life's origins, volcanism, and global elemental cycles. Analysis reveals higher melting than expected, with implications for magma formation and ocean floor volcanism, as well as insights into olivine reactions with seawater that produce hydrogen, potentially fueling early life. This work was conduc..

Scientists obtain deepest rock sample from Earth's mantle

Scientists drilled a record-breaking 4,160-foot hole in Earth's mantle at the Atlantis Massif, recovering a 2,907-foot core sample that reveals mantle rock composition, including olivine and orthopyroxene, and their reactions with seawater to release hydrogen and form methane, which may have supported microbial life and the origin of life on Earth; the sample also shows extensive evidence of melting and melt migration in the upper mantle.
