Abstract—During the 50th cruise of R/V Akademik Mstislav Keldysh, on the south slope of the Atlantis massif
(30°07N; the Middle Atlantic Ridge), an inactive hydrothermal field named the Lost Village was discovered.
This new field was formed of light carbonate rock and was located near the active Lost City hydrothermal field.
The mineralogical associations of these fields were studied. A conclusion about the participation the ocean
water in the changing of the carbonate composition of the inactive hydrothermal field was reached.
