摘要
在分析矿区内含金黄铁矿脉的产出特征以及镜下特征的基础上,应用水压致裂的原理来解释矿化细脉的成因,并结合控矿构造的演化,进一步阐述超高压流体的保持与释放机制,重新认识了成矿初期阶段中形成的自形粗粒黄铁矿与金富集之间的关系。
Based on the analysis of the occurrence characteristics of gold bearing pyrite veins in the area and its microscopic characteristics, the paper explained the origin of mineralized veins using the principle of water pressure caused fracturing and further discussed the mechanism of holding and releasing super pressure fluid, combined with the evolvement of the ore controlling structure, recognizing the relation of idiomorphic coarse pyrite formed at the initial ore forming stage with gold enrichment.
