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^-, SO₄^2- and F^- showed relative high concentrations among detected anions.
