Gold colloids occur in black smoker fluids from the Niua South hydrothermal vent field, Lau Basin (South Pacific Ocean), confirming the long-standing hypothesis that gold may undergo colloidal transport in hydrothermal fluids. Six black smoker vents, varying in temperature from 250 degrees C to 325 degrees C, were sampled; the 325 degrees C vent was boiling at the time of sampling and the 250 degrees C fluids were diffusely venting. Native gold particles ranging from
