| 摘 要： | 小寺沟、轿顶山矿化是由中等盐度的流体侵位于浅部脆性岩石、通过较为迅速的沉淀机制形成的,指示轿顶山具有寻找类似小寺沟斑岩型矿床的潜力;寿王坟矿床的形成与低盐度的流体侵位于深度较大、韧性程度较高的围岩中,与较长时间的渗透交代作用方式有关,不具备形成斑岩型矿床的某些必要条件。研究结果为有关矿区成矿预测提供了矿床成因学方面的论据。

| Abstract: | This contrast study reports the investigation of fluid inclusions of three ore deposits
from Shouwangfen-Xiaosigou region. These results together with other features of ore
geology reveal that Xiaosigou and Jiaodingshan mineralization were formed by the medium-
salt-content fluids which entered the brittle rocks in the shallow level by way of a quick-
depositing mechanism, which indicates that there is a potential area in Jiaodingshan where
a deposit like Xiaosigou Cu-Mo deposit of porphyry may be discovered. But Shouwangfen
mineralization was formed by low-salt-content fluid which entered the ductile rocks in the
deep level by way of a long-time permeation and replacement mechanism, which does not
possess those conditions that are necessary to form the porphyry type deposit. The under-
standing of fluid characteristics and their geological meaning may provide the evidence of
ore-forming genesis for metallogenic prognosis of the studied ore field. |
