| 中文摘要: |
| 探讨康定县三碉金矿床的流体包裹体特征，分析成矿流体的性质，有助于该区成矿条件的认识。通过使用显微冷热台检测该矿床流体包裹体样本的温度，得到该矿床的均一温度、冰点数据，分析其成矿物理化学条件。结果显示，样品的均一温度集中在140~320℃之间，部分样品的均一温度接近500℃；盐度w（NaCl， eqv）集中于6.79%~35.30%之间，部分样品的盐度w（NaCl， eqv）已达56.06%；密度在0.9935~1.7004 g/cm3之间变化，平均值为1.136 g/cm3。由此表明，三碉金矿床的成矿流体具有中高温度、中高盐度、中高密度等特征，地幔流体和地壳流体均参与了成矿。 |
| 英文摘要: |
| This paper discusses the characteristics of fluid inclusions in Sandiao gold deposit, Kangding County, and analyzes the properties of ore-forming fluid, which will help to understand the metallogenic conditions in this area. Micro cold and hot platform is used to measure homogenization temperature and freezing point of the deposit. Data are obtained and processed to analyze the physical and chemical conditions of the deposit. Homogenization temperature of samples is generally in range of 140℃-320℃, and those of some samples close to 500℃, the salinity in range of w(NaCl, eqv)=6.79% to 35.30%, and those of some w(NaCl, eqv)=56.06%, the density varies from 0.993 5 g/cm3 to 1.700 4 g/cm3 with the average value of 1.136 g/cm3 suggesting that ore-forming fluid of Sandiao gold deposit is characteristic of medium high temperature, medium high salinity and medium high density and mantle fluid and crustal fluid are involved in the mineralization. |
