Melting in the mantle in the presence of carbon: Review of experiments and discussion on the origin of carbonatites

T Hammouda, S Keshav - Chemical Geology, 2015 - Elsevier
Carbon emission at volcanic centers requires a constant balance between output (mostly by

Deep electrical imaging of the ultraslow-spreading Mohns Ridge

SE Johansen, M Panzner, R Mittet, HEF Amundsen… - Nature, 2019 - nature.com
More than a third of mid-ocean ridges have a spreading rate of less than 20 millimetres a
