杜荒岭金矿床产出于石英闪长岩中,矿化类型分爆破角砾岩筒型及放射状裂控蚀变岩型。流体包裹体研究表明,两类矿石石英中主要发育含NaCl子矿物三相、气相—富气相及气液二相等3种类型的原生流体包裹体。测温结果显示,包裹体均一温度总体为256.8~450℃,盐度S(NaCl)为31.9%~44.2%,反映了成矿流体为一类中高温、高盐度不均一的热液体系,具明显的浅成岩浆来源特征。
The Duhuangling gold deposit is produced in quartz diorite, mineralized fractured breccia tubular and radial fissured altered rock. Fluid inclusion studies show that three types of primary fluid inclusions including three phases of NaCl minerals, gas-rich phase and gas-liquid two phases are mainly developed in two types of ore quartz. The results of temperature measurement show that the homogenization temperature of inclusions is 256.8-450 ℃, and the salinity S (NaCl) is 31.9% ~ 44.2%, which indicates that the ore-forming fluid is a kind of hydrothermal system with medium-high temperature and high salinity heterogeneity. Clearly magmatic source characteristics.
