Solid Earth Carbon Degassing and Sequestration Since 1 Billion Years Ago

Geochemistry, Geophysics, Geosystems
Solid Earth CO2 outgassing, driven by plate tectonic processes, is a key driver of carbon cycle models. However, the magnitudes and variations in outgassing are poorly constrained in deep‐time.

MORPHOSTRUCTURE OF ATLANTIC’S BOTTOM AND MEDIUM ATLANTIC RIDGE

Геологія і корисні копалини Світового океану, 2019
The purpose of the study is to characterize the morphostructure and geology of Atlantic's bottom and the Mid Atlantic Ridge using generalized and new data. The basis is the bathymetric map of the Atlantic 1971, according to research data of the Institute

The carbon isotopic signature of the upper mantle is heterogeneous

Communications Earth & Environment
Knowledge of the carbon isotopic (δ13C) signature of the mantle source region of mid–ocean ridge basalts, is key to understanding carbon cycling on a planetary scale.

Active Plume, Abandoned Ridge, or Ancient Slab? olivine‐Hosted Melt Inclusions Record the Mantle Melting Conditions Below the East Pacific Revillagigedo Archipelago, Mexico

Geochemistry, Geophysics, Geosystems
The voluminous active volcanoes of the Revillagigedo Islands of Socorro and San Benedicto in the east Pacific Ocean exhibit hotspot geochemistry. However, the presence of a deep mantle plume has not been seismologically confirmed.
