Synorogenic hydrothermal origin for giant Hamersley iron oxide ore
Oxygen isotopes and fluid inclusions from veins and ore indicate that oxidizing fluids at temperatures >200 °C and locally up to 400 °C were involved. Regional circulation of hydrothermal fluids, including heated surface water, through reduced banded iron formations occurred during or soon after the Ophthalmian orogeny.
