Summary: A major high-T hydrothermal area has been located in the Mid-Atlantic Ridge rift valley approx 25 km south of the Kane Fracture Zone. The vent field consists of a wide area (40 000 m2) of dark hydrothermal deposits, numerous sulphide chimneys and mounds, some up to 11 m high, and high-T 'black smoker' vents. Ten shallow holes, the first ever drilled in an active submarine hydrothermal area, recovered friable, unconsolidated Fe, Fe-Cu and Zn sulphides and several large fragments of massive sulphide, mainly chalcopyrite. The greater thickness and freshness of the sulphide deposits and association of an unusual biological community of smaller and more mobile organisms are the main differences of the Snake Pit deposits from the East Pacific Rise ones.
