Hydrothermal fluids of seawater salinity in ophiolitic sulphide ore deposits in Cyprus

Abstract

Freezing points of fluid inclusions in vein quartz intergrown with sulphides from ophiolitic cupriferous pyrite ore deposits in Cyprus indicate a hydrothermal fluid of seawater salinity, and confirm the hypothesis of metal transport in hot seawater. It is therefore suggested that the economic potential of oceanic crust layer 2 is probably negligible.
