Researchers studying ocean transform faults,
<p>•This study reports widespread mineral carbonation of mantle rocks in an oceanic transform fueled by magmatic degassing of CO<sub>2</sub>. </p> <p>•The findings describe a previously unknown part of the geological carbon cycle in transform faults that represent one of the three principal plate boundaries on Earth. </p> <p>•The confluence of tectonically exhumed mantle rocks and CO<sub>2</sub>-rich alkaline basalt formed through limited extents of melting characteristic of the St. Paul&rsqu...
