The helium isotopes composition of hydrothermal fluids at the Lucky Strike vent field has been determined by mass spectrometry. [ super(4)He] end-member concentration is in the 1.2 x 10 super(-5)-2.6 x 10 super(-5) cm super(3) STP/g range and the super(3)He/ super(4)He ratio, R, is 8.13 plus or minu...
