摘要
传统上将小兴安岭霍吉河钼矿床归类为斑岩型钼矿.通过对矿区地质特征的研究,即矿区无斑岩体、矿体围绕隐爆角砾岩呈环状出露、石英细脉-网脉状和浸染状矿石结构、成矿年龄明显晚于赋矿围岩形成时间等,认为该矿床是透岩浆成矿作用的结果.早中生代伊春-延寿花岗岩岩基带上相伴的大型—超大型钼矿是典型的透岩浆成矿作用的产物,是岩基后成矿作用.
Traditionally,the Huojihe molybdenum deposit in Xiaoxinganling Mountains is classified as porphyry type.With study on its geological characteristics such as non-porphyritic mass,orebodies circling around the cryptoexplosive breccia,veinlet-network and disseminated structures of quartz and the metallogenic age obviously later than forming time of host rock,it is believed that the deposit is formed by transmagmatic mineralization. The large-super large molybdenum deposit associated with the Early Mesozoic Yichun-Yanshou granitic batholith belt is a typical product of post-batholith metallogenesis.
