摘要

摘要: 新疆和静县大山口金矿床成矿流体地球化学特征为:成矿流体属K⁺-Na⁺-SO₄^2--Cl^--CO₂型;具有低盐度和低密度特点;成矿温度:早期为219℃,主成矿期为298.28℃。成矿热液具有以岩浆热液为主的特点。该金矿属于受控于韧性剪切带内的以岩浆热液为主的贫硫化物型金矿床。

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.
