Two types of hydrothermal massive sulfide fields were discovered in the Mid-Atlantic ridge (MAR) in the last twenty years. The first type associates with basalts and includes the TAG, Snakepit, Broken Spur, Lucky Strike and Krasnov hydrothermal fields. The second type is related to ultramafic rocks and represented by the Logatchev, Rainbow and Ashadze hydrothermal fields. In 2007 a new, probably, the largest cluster of hydrothermal massive sulfide field on the MAR (Fig. 1), related both to basaltic and ultramafic rocks, was discovered at 13°31'N of the MAR (Beltenev et al., 2007).
