摘　　要：通过对铁列克特金矿的地质特征观察与分析,并对矿体中的石英进行流体包裹体研究发现:铁列克特金矿的流体包裹体有三种类型:纯液相流体包裹体、气液两相流体包裹体、气液固三相流体包裹体,其中气液两相流体包裹体占有大多数,但是含子晶的流体包裹体较少,未发现含有CO_2的流体包裹体.测温可知均一温度在105~347.2℃,主要集中在130~220℃之间,冰点的温度为-0.5~6.7℃之间,计算得出的盐度在0.53~10.24Wt%NaCl.eqv,流体密度为0.6~1.0g/cm^3.运用Flincor软件计算获得流体包裹体的压力为5~28bar.其流体特征与浅成低温热液金矿趋于一致.Based on the observation and analysisof the geological characteristics of Tieliekete golddeposit and the study on the quartz with fluid inclusions in ore body, we have foundthat three types of fluid inclu- sionsexisted in Tieliekete golddeposit： pure liquid fluid inclusions, gas-liquid two-phase fluid inclusions, gass- liquid-solid three-phase fluid inclusions. Gas-liquid two-phase fluid inclusions occupiedthe majority fluid in- clusions, but less fluid inclusions containing child crystal andno fluid inclusions containing CO2.Temperature test shows that the completely homogeneous temperatures are in 105 - 347.2 ~ ,mainly in 130 ~ 220 ℃, freez- ing temperatures are in -0.5 --6.7℃. The calculated salinityis in 0.53 - 10.24 Wt% NaCl.eqv and the fluid density is in 0.6 - 1.0g/cm3. Using Flincor software we calculatedthat the pressure of the fluid inclusions is in 5- 28bar. The fluid characteristicsin Tieliekete gold deposit tends to be uniform with epithermal gold deposits.
