| 中文摘要: |
| 本文通过对黔北桑木场地区铅锌矿流体包裹体特征的研究，结果表明，流体包裹体均一温度在130℃210℃之间，存在130℃150℃与170℃210℃两个峰值区间；含盐度较高，均值在839%2181%；密度主体在100105 g/cm3，显示铅锌矿成矿流体具中低温度、高等密度、高盐度特征 。并研究认为区内铅锌矿与MVT型铅锌矿关系密切，具两期热液活动。 |
| 英文摘要: |
| Based on the study of fluid inclusion characteristics of lead-zinc deposits in Sangmuchang area, northern Guizhou, the results show that the homogenization temperature of fluid inclusions is between 130℃210℃, and there are two peak ranges of 130℃150℃ and 170℃210 ℃. The salinity is high, with an average value of 8.39%21.81%. The density of ore-forming fluids is 1.00 g/cm31.05 g/cm3, indicating that the ore-forming fluids of lead-zinc deposits are characterized by low temperature, high density and high. It is considered that the lead-zinc deposits in this area are closely related to MVT type lead-zinc deposits and have hydrothermal activities of two period. |
