Continuous exhumation of mantle-derived rocks at the Southwest Indian Ridge for 11 million years

The sea floor at the easternmost Southwest Indian mid-ocean ridge is smooth, unlike that at other mid-ocean ridges. Sonar imaging and analysis of rock samples show that the sea floor here is composed almost entirely of sea-water-altered mantle rocks that have been brought to the surface by large faults on both sides of the ridge axis over the past 11 million years.

Fluid-assisted grain size reduction leads to strain localization in oceanic transform faults

Deformed mantle rocks exhumed by oceanic transform faults recorded fluid-assisted ductile deformation at high temperatures and pressures, corresponding to the root of the fault. This deformation mechanism controls deep faulting at plate boundaries.

Heterogeneous Earth’s mantle drilled at an embryonic ocean

Integrated Ocean Discovery Program Expedition 402 drilled two in-situ long mantle sections in the Tyrrhenian Sea, revealing that retention of large quantities of melts at mantle levels delayed the birth of an ocean basin.

Thermal effects of pyroxenites on mantle melting below mid-ocean ridges

Pyroxenite—recycled, subducted material—beneath mid-ocean ridges cools the mantle, suppressing melt extraction and crust formation, according to geochemical analyses of samples taken from the Mid-Atlantic Ridge.

Deep mantle earthquakes linked to CO₂ degassing at the Mid-Atlantic Ridge

Deep mantle earthquakes (10–20 km) are reported beneath the Mid-Atlantic Ridge, likely triggered by CO₂ degassing in mantle melt. This highlights a link between melt behavior and earthquake mechanisms, offering insights into deep mantle processes.

Abiotic formation of condensed carbonaceous matter in the hydrating oceanic crust

Thermodynamic calculations suggest that condensed carbonaceous matter should be the dominant product of abiotic organic synthesis during serpentinization of the oceanic crust at Mid-Ocean Ridges. Here the authors report natural occurrences of such carbonaceous matter formed during low temperature alteration.

Extreme mantle uplift and exhumation along a transpressive transform fault

Earth’s crust diverges and extends along mid-ocean ridges. Analyses of gravity and seismic data from the equatorial Atlantic show that propagation of ridge segments can compress the crust and create sufficient uplift to create small islands.

Life in the hydrated suboceanic mantle

In the roots of the ocean crust, mantle-derived rocks are progressively hydrated by hydrothermal circulation. Raman spectroscopic analyses of hydrated rocks sampled from the ocean floor reveal accumulations of organic matter, which point to the hydration process as a possible energy source.
