Salinity of fluid inclusions in jadeitites – Does it depend on depths?

Abstract

Major components and salinity of fluid inclusions in jadeitites were examined. The fluid inclusions consist of H₂O ± CH₄. The salinity is 7-8 wt% NaCl equivalent in the quartz-free jadeitites and is typically about 5 wt% NaCl equivalant in the quartz-bearing jadeitites. This result suggests that salinity of fluid decreases with depth in subduction zones.
