摘要
通过野外踏勘采样,室内对样品进行流体包裹体研究,了解其成矿流体的温度以及盐度,并利用所测定的数据来圈定热晕和盐晕,以此阐明矿床的成因和演化,建立成矿模式,对西藏跃进沟铜多金属矿床进行了深入研究.结果表明,跃进沟铜多金属矿床成矿早期流体包裹体均一温度较高,变化范围为400～430℃,主要成矿期包裹体均一温度明显降低,变化范围为250～370℃.成矿热液的盐度范围为7.0%～20.0%,可以得出该矿床为中高温中等盐度的热液型矿床.
Based on the samples from the geological field and the inside fluid inclusion, the metallogenic temperature and the salinity of the fluid are obtained,, and by using the surveyed data the delimitated saline and the thermol blooming can be deduced which illuminate the ore genesis and evolution, and a metallogenic model is built for the further researches on Yuejingou copper polymetallic deposit in Tibet. The results show that the homogenization temperatures of fluid inclusion is higher, ranging from 400℃ to 430℃ in the early period, and lower in the later period, ranging from 250℃ to 370℃. And the salinity of hydrothermal deposits of hydrothermal deposits is from 7 per cent - 20 per cent, which shows the mineral deposit should be of mid - high temperature and middle salinity hydrothermal deposit.
