| 摘 要： | 本文对产于太古代深变质岩中的水晶屯石英脉蚀变接触带型金矿床的脉石英进行了稀土元素调查,结果表明该矿区含金石英脉存在两种稀土元素分布型式,它们可能分别与两次不同性质的地质作用相联系,具有向右缓倾型稀土分布曲线的石英脉有较大的成矿潜力。

| Abstract: | Shuijingtun gold deposit is at 26 km east of Zhangjiakou city in the north part of Hebei
Province. The mineralization belongs to the type of altered guartz vein, developed in the high
degree of metamorphic rocks. Through the analysis of REE for the quartz veins in different di-
rections and positions. two types of REE patterns are obtained. The orebody and the quartz
veins gold-rich have lower REE contents and smaller ratio of LREE/HREE, which is very
close to that of Luojiaying porphyritic granite surrounding the district and suggests the pouible
original relationship between them. However, the quartz veins of NW-SE direction have very
high REE contents, large LREE/HREE ratio and steep curves, which is consistant with the
migmatized granite and the light-coloured granulites near the district, and suggests their rela-
tionship in origin. Therefore, the REE features can be used as an important indicator for the
exploration of gold in this region. |
