摘要
通过对庞家河金矿内多条花岗斑岩地质特征及展布特征的详细研究和分析认为,花岗斑岩不仅是本区金矿成矿提供了热源条件,还是重要的金源提供者和容矿围岩。矿体主要分布是花岗斑岩的内外接触带附近。花岗斑岩可以作为本区找矿的重要标志之一。
Through detailed research and analysis of the pangjiahe gold deposit in a number of geological characteristics of granite porphyry and the distribution characteristics of the thought, not only is the granite porphyry gold metallogenic area provided heat conditions, is an important ore provider and Jin Yuan. The ore body is mainly distributed near the inner and outer contact zone of granite porphyry. Granite porphyry can be regarded as one of the important signs of ore prospecting in this area.
