Chemical and mineral compositions of hydrothermal sulfide deposits from the Lucky Strike hydrothermal field, Mid-Atlantic Ridge

Bathymetric position of these structures varies by approximately 100 m. Investigation of chemical and mineral compositions of hydrothermal ore occurrences led to the conclusion that the initial high-temperature ore-bearing solution ascending toward the surface became unstable and experienced phase separation beneath the ocean floor.

The phase separation was responsible for bathymetric control of hydrothermal ore formation within the field.
