摘要
红旗岭镍矿区是我国岩浆岩型铜、镍硫化矿床的主要矿化集中区之一,以往勘查中只在1号岩体中发现中型铜、镍矿床,在7号岩体中发现大型铜、镍矿床,目前在3号岩体深部发现了厚大镍、钴矿体.对3号岩体岩石学特征、岩体微量元素特征、岩体稀土元素地球化学特征等方面进行分析,对矿床成因进行了探讨.认为该岩体矿石与镁铁-超镁铁质岩具同源性,矿床属岩浆深部熔离分异成因,并发生就地熔离和重力分异.
The Hongqiling nickel orefield is a significant concentrated mineralization zone of copper-nickel sulfide of magmatic type in China. Previous exploration has found middle-sized copper-nickel deposit in No. 1 rock body and large scaled copper-nickel deposit in No. 7 rock body. Presently, a large and thick nickel-cobah ore body is discovered in the deep of No. 3 rock body. With studies on the lithology, microelements and REE geochemistry of the rock body, the genesis of the deposit is discussed. It is concluded that there is an affinity between the ore rock body and the mafic-uhramafic rock. The deposit is genetically formed by deep magmatic liquation and differentiation.
