Highly saline fluid inclusions in Chamundi granite, South India

Fluid inclusions in minerals and rock represent a potentially valuable source of information about the composition and density of fluids present during the formation and evolution of rocks. Our preliminary studies on Chamundi granite have indicated presence of highly saline inclusions (up to 50–60 w...

Description
Summary:Fluid inclusions in minerals and rock represent a potentially valuable source of information about the composition and density of fluids present during the formation and evolution of rocks. Our preliminary studies on Chamundi granite have indicated presence of highly saline inclusions (up to 50–60 wt.% Nacl equivalent) as well as low-salinity inclusions (8 to 22 wt.% NaCl equivalent). Data on temperature of homogenization suggest that they represent remnant fluids of magmatic origin trapped in minerals.
