Abstract
One of the major causes of change in the chloride/boron ratio across a geothermal reservoir is the volality of boron. Analysis of boron in separated steam and water from fluids discharged by Wairakei and Ohaaki-Broadlands wells together with some published data have enabled the relationship of boron distribution between vapour and liquid with temperature to be defined. log (boron in vapour/boron in liquid) = -0.947 x log (density of liquid/density of vapgur) + 0.0547 (density of liquid/density of vapour) . While volatility of boron can explain the creation of shallow boron rich waters, other mechanisms are needed to explain the formation of boron deficient waters.
