Carbon fixation by basalt-hosted microbial communities
Frontiers in Microbiology, 2015 Oceanic crust is a massive potential habitat for microbial life on Earth, yet our understanding of this ecosystem is limited due to difficulty in access. In particular, measurements of rates of microbial activity are sparse. We used stable carbon isotope

Subduction Initiation by Plume‐Plateau Interaction: Insights From Numerical Models
Geochemistry, Geophysics, Geosystems, 2020 It has recently been demonstrated that the interaction of a mantle plume with sufficiently old oceanic lithosphere can initiate subduction. However, the existence of large lithospheric heterogeneities, such as a buoyant plateau, in proximity to a rising ...

The MoHole: A Crustal Journey and Mantle Quest, Workshop in Kanazawa, Japan, 3–5 June 2010 [PDF]
Scientific Drilling, 2010 Drilling an ultra-deep hole in an intact portion of oceanic lithosphere, through the crust to the Mohorovičić discontinuity (the ‘Moho’), and into the uppermost mantle is a long-standing ambition of scientific ocean drilling (Bascom, 1961; Shor, 1985 ...

Crustal structure across the eastern North American margin from ambient noise tomography
Geophysical Research Letters, 2017 Passive tectonic margins, like the eastern North American margin (ENAM), represent the meeting of oceanic and continental material where no active deformation is occurring.

Increased metamorphic conditions in the lower crust during oceanic transform fault evolution [PDF]
Solid EarthOceanic transform faults connect the segments of active spreading ridges that slide past each other. In a classical view, transform faults are considered conservative, where no material is added or destroyed.

Mechanism of crustal extension in the Laxmi Basin, Arabian Sea
Geodesy and Geodynamics, 2015 Continental rifting and magmatism has been extensively studied worldwide as it is believed that continental rifting, break up of continents and associated magmatism lead to genesis of new oceanic crust.

EARTH CRUST IN OCEANS AND STRIP ANOMALIES OF MAGNETIC FIELD
Геологія і корисні копалини Світового океану, 2019 Examples of the isolation and interpretation of the strip anomalies of the magnetic field of the oceans are considered. Data were used on the eastern edge of the Pacific Ocean over most of the western coast of North America and on the Knipovich Ridge at ...

Mafic High‐Pressure Rocks Are Preferentially Exhumed From Warm Subduction Settings
Geochemistry, Geophysics, Geosystems, 2018 The oceanic crust that enters a subduction zone is generally recycled to great depth. In rare and punctuated episodes, however, blueschists and eclogites derived from subducted oceanic crust are exhumed.

Frontiers in Microbiology, 2019 One of the most promising planetary bodies that might harbor extraterrestrial life is Mars, given the presence of liquid water in the deep subsurface. The upper crust of Mars is mainly composed of >3.7-billion-year-old basaltic lava where heat-driven ...
