| 摘 要： | 鹿鸣钼矿床是小兴安岭—张广才岭成矿带上典型的特大型斑岩型钼矿床,矿体主要产于早中生代早期中细粒似斑状二长花岗岩内,矿化类型以细脉浸染状矿化为主。根据矿物共生组合及脉体穿插关系将鹿鸣钼矿床划分为4个成矿阶段:黄铁矿-石英阶段(Ⅰ),石英-辉钼矿阶段(Ⅱ),绿泥石-辉钼矿-石英阶段(Ⅲ),石英-碳酸盐阶段(Ⅳ)。成矿流体包裹体有3类:A型气液两相包裹体(L+V),B型含子晶三相包裹体(L+V+S),C型气相包裹体(V)。不同阶段流体包裹体的成分、均一温度、盐度等特征显示成矿流体由早阶段的高温、高盐度的H_2O-CO_2-NaCl体系逐渐演变为晚阶段的低温、低盐度的H_2O-NaCl体系。氢氧同位素特征显示成矿早阶段以岩浆水为主,随成矿演化有不同程度大气水的加入。根据矿床产出特征、矿物共生组合和流体包裹体特征,认为流体的沸腾作用和CO2等气相组分大量逸失是成矿流体形成矿床的主要因素。
