摘要
通过矿体脉石英中原生流体包裹体研究,表明纳日贡玛铜矿具有典型的斑岩型铜矿流体包裹体地球化学特征.研究表明:纳日贡玛斑岩铜矿成矿温度为246～300 ℃,具高盐度特点,w(NaCl)为31.3%～42.2%,且其矿体均产于高盐度包裹体分布范围内.成矿流体属岩浆水和大气水的混合流体,具沸腾特征.
Primary inclusions in quartz veins show the Narigongma copper deposit has fluid inclusion geochemistry that is typical of porphyry copper deposits. Ore-forming temperatures at Narigongma were 246℃ to 300℃. Salinity is high ranging from 31.3 to 42.4 wt%. The ore-forming fluid is a mixture of magmatic and meteoric waters and has the character of ebullition.
