摘要
Bulk volatiles and ions and stable isotope compositions of inclusion fluids in quartz of altered granitoids from Damoqujia gold deposit were studied in order to reveal gold ore fluid evolution and to trace its possible sources. It was showed that bulk inclusion fluid volatiles were dominated by H2O and CO2, with small amount of CH4, C2H6, H2S, N2 and Ar2. K+ and Na+ are the dominant cations in inclusion fluid with minor Ca2+ and Mg2+. Cl-, SO42- and F- showed relative high concentrations among detected anions.
