摘要
吉林红旗岭地区是我国岩浆型铜镍硫化物矿床的主要矿化集中区之一。在区内已发现的镁铁质-超镁铁质岩体中,有的含有铜镍矿床或铜镍矿化,有的则不含矿。通过本区含矿与不含矿岩体的形成时代、岩石组合、橄榄石矿物成分、岩石化学成分和微量元素组合特征的对比,建立起镁铁质-超镁铁质岩体含镍性的评价标志,为隐伏岩体和新发现岩体含矿性的评价提供了理论依据。
Hongqiling area in Jilin province is one of the major metallogenic areas of magmatic Ni-Cu sulfide deposits in China. There are about 50 mafic and ultramafic intrusions in this area. Among them some hosts the Ni-Cu sulfide deposits, but some does not. Based on the comparison of rock-forming ages, rock assemblages, olivine composition and trace element association between the Ni-bearing and Ni-barren mafic and ultramafic intrusions, the assessment index of ore-bearing potentiality of the intrusions have been set up.
