Abstract

Abstract

The characteristics of fluid inclusion in Dashankou gold deposit, Xinjiang, belong to K⁺-Na⁺-SO₄^2--Cl^--CO₂ type.The salinity and density are all low degree.The ore-forming temperature of No.1 stage is 219.92℃ with pressure 22.14×10⁵ Pa, and the main ore-forming stage is 298.28℃ with pressure 27.98×10⁵ Pa.Thus the deposit belongs to low-middle temperature system.The fluid origenates mainly from magmatic water, or may be mixed with a small quatity of other source of waters.The gold deposit belongs to poor-sulfide type gold deposit and is controled by shear zone.
