Hydrothermal Fluxes along the Mohns Ridge - Implications for Mineral Resources at Ultraslow Spreading Ridges
By RB. Pedersen, T. Barryere, E. Reeves, A. Stensland, I. Thorseth, T. Baumberger
Venting on ultraslow spreading ridges is far more abundant then previously predicted, and the discrepancy between observed and predicted vent field density may imply that non-magmatic heat sources are
