内蒙古宁城热水金矿闪长岩脉特征及其控矿规律

The Characteristics and ore-controlling regularity of the diorite-dyke in Resui Gold Deposit of Ningcheng,Inner Mongolia

通过对热水金矿床闪长岩脉的地质特征、岩石化学、稀土元素配分特征的分析与讨论 ,认为热水金矿床的金矿化与闪长岩脉有着亲密的时空与成因联系 ,对金矿化起到了主要的控制作用 ,而并非为前人所提出的与河落堡花岗岩体有关 ,并根据脉岩控矿的新认识提出了进一步找矿与勘探的方向。

According to the analysis of the geological,petrochemical,rare-earth-elements characteristics of the diorite-dykes in Resui gold deposit,this article considers that it has close relationship between the diorite-dyke and the gold metallogenesis in the gold deposits.Thus,it draws different conclusion from the former researchers.Furthermore,some suggestions are raised to help the mining exploration and resource prediction works.
