The release of the brines was attributed, again, to melting by localized volcanic heat sources.
Metal fractionation between magmatic brine and vapour, determined by microanalysis of fluid inclusions.
The highly concentrated nature of the brine had two other consequences.
Thus brines expelled at a later time might have been both magnesium-rich and saline.
The brine is cooled by an external cooling unit.
The density of the brine in the reservoir was measured using a hydrometer accurate to 0.0005 g ml-1.
The brine was pumped from a reservoir tank and the flow rate measured using a flow meter.
They are used in the solar evaporation of the brine.
