Figure 1. Location of active and inactive hydrothermal fields and sulfide mineralization in the northern part of the Mid-Atlantic Ridge. Hereinafter, latitudes and longitudes are given in degrees (to the first decimal place). Topographic base, from satellite altimetry data [Smith and Sandwell, 1997]. Earthquake epicenters, from CNSS Earthquake Composite Catalog.
1-2 hydrothermal fields: 1 - active (with proper names) and 2 - inactive; 3 - sulfide mineralization; 4 - hydrothermal alteration; 5 - metalliferous sediments; 6 - methane plume; 7 - area with potential for sulfide mineralization and/or active hydrothermal fields; 8 - earthquake epicenter.
