平邑磨坊沟金矿床矿物包裹体特征及与成矿阶段的关系

Characteristics and Evolution of Ore Inclusions in Mofanggou Gold Deposit

摘要:

对磨坊沟金矿床流体包裹体进行了测试研究 ,结果表明主要成矿阶段的温度为 1 2 0～360℃ ,包裹体盐度在 0 .35 %～ 2 0 .6%之间 ,压力在 1 .73× 1 0 5～ 44.1 8× 1 0 5Pa之间 ,密度为0 .80～ 1 .0 9g/cm3。推测该矿床形成深度为 5 0 0～ 1 0 0 0m ,成矿流体来源于岩浆水和大气降水。

Abstract:

Fluid inclusions of Mofanggou gold deposit are tested and studied. As the result showed, the temperature of fluid inclusion in major ore-forming period is 120～360℃, salinity 0.35%～20.6%, pressure 1.73×10 5～44.18×10 5Pa, and denseness 0.80～1.09g/cm 3. It is inferred that the forming depth of this deposit is 500～1000m, and ore-forming fluid is from magmatic water and hydrothermal water.
