摘要： 鹿鸣钼矿床位于小兴安岭-张广才岭成矿带中南部.钼矿体产于二长花岗岩与花岗斑岩的接触带内，钼矿化主要载体为石英脉，呈脉状、网脉状分布于矿体的内部.研究了主要含矿石英脉体中流体包裹体的特征，结果表明:包裹体相态类型主要为气液两相，矿床的成矿温度峰值分别为400，220℃，盐度为19%~144%，成矿压力平均为18MPa，成矿深度为09~28km，成矿流体成分富含CO2，H2O，CH4等多种气态组分，以及Na+，Ca2+，SO2-4，Cl-液态组分；矿床初始流体来源于岩浆热液，成矿后期受大气降水的混入.矿床成因类型应划归为与中酸性侵入岩浆活动有关的中高温斑岩型钼矿床.

Abstract: The Luming deposit lies in the southcentral block of the Xiaoxingan MountainsZhangguangcai Mountain polymetallic belt. Its major orebodies are hosted in the contact zones of the monzonitic granite and granite porphyry. The Mo ores occur in the quartz vein and distribute in the orebody with veinlet and stockwork shapes. The characteristics of the ore fluid inclusions trapped in quartz were studied deeply. The results showed that fluid inclusions in minerals are mostly vaporliquid (aqueous twophase) inclusions. The peak value of the homogenization temperature are 400， 220℃， respectively. The salinity of the fluid inclusions varies in 19%~144%. The average mineralization pressures are 18MPa， wheres the oreforming depths are in the range of 09~28km. The gas composition of the oreforming fluid are mainly CO2， H2O and CH4. Liquid composition are mainly Na+， Ca2+， SO2-4， Cl-. The fluid is mainly derived from the magma water， and a minor part from meteoric water mixed in the later. It is concluded that the Luming porphyry Mo deposit should be of hightomodtemperature hot liquid origin relevant to the acidintermediate intrusive magmation.
